Callianassa Leach 1814

"This species is recorded by Milne-Edwards from Martinique, but I am unable to find any difference between our Maldive specimen and his description. Milne-Edwards gives no figure, but a comparison will be made more easy by that in the accompanying plate." (Borradaile, 1904)

"The specimen is small and the carapace very soft, so that the lines on it are not easily seen. Fig. 12.5, on p. 691 above, is from the New Britain specimen, and shows well the two longitudinal lines — linea thalassinica and linea anomurica which, by a very rare exception, are here found together." (Borradaile, 1904)

"A Callianassa with the eyestalks short, flattened, pointed, with the cornea on the outside; the rostrum sharp, reaching to the end of the cornea; no antennal tooth on the carapace; the segments of the abdomen about equal, but the first rather shorter, and the second rather longer than the rest; the third joint of the antennular stalk longer than the others, as long as the flagella; the third maxillipeds with the ischiopodite and meropodite broad, but the last three joints narrow; the palm of the great chela as broad as, and about twice as long as, the wrist, both wrist and palm sharp-edged above and below, scantily hairy except on the fingers, the lower edge of the palm .saw-like within at the base, that of the ischiopodite and meropodite with strong curved teeth; the telson as long as the sixth abdominal limb." (Borradaile, 1904)

"Taken between tide-marks at Goidu, Goif'urfehendu Atoll." (Borradaile, 1904)

"Taken between tide-marks at Goidu, Goifurfehendu Atoll." (Borradaile, 1904)

"Taken between tide-marks at Hulule, Male Atoll." (Borradaile, 1904)

"Length of the single specimen: 19 mm." (Borradaile, 1904)

Callianassa is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus (C. candida, C. tyrrhena and C. whitei) have been split off into a new genus, Pestarella, while others such as Callianassa filholi have been moved to Biffarius.
