The above list of references is a selected one, including synonyms, illustrations, summary articles, and/or those pertaining to the occurrence of the species in Georgia. The latter are marked with an asterisk. A complete list of references prior to 1948 is included in Hobbs (1948:224).

SUMMARY OF LITERATURE.—In his revision of the genus Cambarus, Hobbs (1969a) placed this crayfish in the newly erected genus Fallicambarus, and, in reviewing the members of the genus (1973a), he assigned it to the subgenus Creaserinus. Most of the literature dealing with this species is based on records of its occurrence in Louisiana, Oklahoma, Tennessee, and Texas. The few data available on its life history, habits, and habitat may be found in Hobbs (1948:228), Penn and Hobbs (1958:477–478), Penn (1959:16), Hobbs and Hart (1959:187–188), and Reimer and Clark (1974:175).

All of the references to its presence in Georgia are based on six specimens from Seminole County that were misidentified by Hobbs and Hart (1959) as Cambarus fodiens and by Hoffman (1963) as C. uhleri. Hart (1959) noted that they served as hosts to the ostracod Entocythere equicurva (= Uncinocythere equicurva). Although he did not cite a specific locality, the specimens from Seminole County were the only members of the species available to him. Uncertainty exists as to the source of the error in the identification of the same six crayfish as Fallicambarus uhleri (Hart and Hart, 1974); perhaps it was based on a tentative identification supplied to them by me. Hoffman (1963) recorded two of the same six specimens as the host of his new branchiobdellid worm, Cambarincola osceola.

An inexplicable error was made by me (Hobbs, 1973b:480) in the “Explanation of Figure 4 and Key to Species.” Couplet “k” should have read as follows:

DIAGNOSIS.—Body pigmented, eyes well developed. Rostrum without marginal spines or tubercles. Areola obliterated along part of length and consisting 38.4 to 40.4 percent of total length of carapace (45.6 to 48.0 percent of postorbital carapace length). Cervical spine small; branchiostegal spine represented at most by small tubercle; hepatic spines absent; suborbital angle obsolete; postorbital ridge without spine or tubercle. Antennal scale approximately 2.5 times as long as wide, broadest distal to midlength. Ischium of third maxilliped with heavy beard of plumose setae mesially, and lateral row of similar setae obscuring much of lateral half of podomere. Chela depressed, with palm bearing 2 well-defined rows of 6 to 8 tubercles mesially; opposable margin of fixed finger with 1 or 2 (latter rarely in Georgia) tubercles larger than others; corresponding margin of dactyl with prominent excision on basal third. Second pereiopod of male with mesial surface of carpus and palm of chela studded with dense mat of plumose setae. First pleopod of first form male with rather long bladelike central projection bearing rudimentary subapical notch, rounded apically, curved gently at about 120 degrees to shaft of appendage, and not reaching tip of mesial process; latter disposed subparallel to central projection, with eminence (“hump”) at midlength not obscuring part of central projection, tapering to rounded apex, somewhat flattened and appearing twisted. Female with annulus ventralis subspindle shaped and firmly fused to sternum; first pleopod reduced to tuberculiform rudiment.

COLOR NOTES (Figure 100).—Based on first form males from Choctaw County, Alabama.) Ground color of body and appendages olive tan overlain with black to greenish tan markings. Cephalic region with irregular small spots except for pale area along anterior part of mandibular and anteroventral branchiostegal region. Anterior triangular area and dorsomedian line of fusion of branchiostegites dark brown to black; dorsal part of latter with scattered dark spots becoming reticulate ventrolaterally over paler olive background; dark spots on caudodorsal part of branchiostegites arranged in paired linear series in line with those on abdomen. Linear series on latter, flanking pale olive median stripe, converging gently posteriorly and uniting at cephalic part of telson in dark spot. Bases of pleura with longitudinal series of dark splotches separated from more dorsal series by pale longitudinal stripe; otherwise pleura pale with small, dark, irregular splotches. Telson and uropods likewise pale olive with irregular pattern of small spots, some forming reticulate pattern. All cephalic and thoracic appendages olive with olive tan to brown splotches.

TYPES.—Holotype, morphotype, USNM 85146 (I, II), and allotype, USNM 85147 (); paratypes, USNM.

TYPE-LOCALITY.—Lower middle part of the Aransas National Wildlife Refuge, Aransas County, Texas.

RANGE.—Oklahoma and Texas eastward to Tennessee and southwestern Georgia. In the latter, it has been found in the southwestern part of the Dougherty Plain and Fall Line Hills districts. The limits of its range and that of the closely allied F. (C.) fodiens (Cottle, 1863:217) have not been accurately determined.

GEORGIA SPECIMENS EXAMINED.—I have examined only nine specimens from the following localities. Early County: (1) along Sawhatchee Creek on St Rte 273, 0.4 mi W of Cedar Springs, 2II, 25 Jun 1975, D.J. Peters, J. E. Pugh, HHH, collectors; (2) ditch 0.7 mi E of Blakely on St Rte 62, 1j, 2 Sep 1955, C. W. Hart, Jr., HHH. Seminole County: (3) Dry Creek 3.1 mi N of Iron City on secondary road, 3II, 1, 1 Sep 1955, CWH, HHH; 1I, 1, 9 Sep 1955, CWH, HHH.

VARIATIONS.—There are few variations of significance among the nine specimens from Georgia: the cephalic section of the telson bears two or three spines in the caudolateral angle; the mesial surface of the carpus of the cheliped has, in addition to the large spikelike tubercle, one to four tubercles proximal to it; the mesial surface of the palm of the chela bears six to eight tubercles in the mesialmost row and five or six in the other, frequently irregular, row. The opposable margin of the fixed finger usually supports one tubercle that is conspicuously the largest, but occasionally there are two larger tubercles that are subequal in size.

SIZE.—The largest specimen from Georgia is the first form male, which has a carapace length of 26.7 (postorbital carapace length 22.5) mm. The largest female has corresponding lengths of 20.1 (16.6) mm. No ovigerous female or one carrying young is available.
