[= Apalone mutica calvata (Webb, 1959); fide, Meylan, 1987:92]

Webb, 1959, Univ. Kansas Publ. Mus. Nat. Hist. 11(9):519, pls. 13–14.

Paratype: USNM 7655 (alcoholic juvenile, CL 59 mm), Monticello, Lawrence County, Mississippi, collected by Helen Teunison, date unknown, cataloged 1872 (see “Remarks”).

Type Locality: “Pearl River, Roses Bluff, 14 miles northeast Jackson, Rankin County, Mississippi.”

Other Type Material: Holotype: UIMNH 31071. Paratypes: KU 47117–19; TU 13473, 16682, 17301, 17302.1(2), 17303.4 (5), 17304.3(4), 17305, 17306.

Etymology: The name calvatus is derived from the Latin calvus, smooth or bald, and refers to the skin surface of the carapace.

Remarks: A metal tag and an early paper tag attached to USNM 7655 were both mistakenly labeled 7652; USNM 7652 is the catalog number of two eggs of “Trionyx [= Apalone] ferox.” However, locality and collector information on an original parchment label attached to the specimen coincides with the catalog record for USNM 7655. A new catalog tag labeled USNM 7655 has been affixed to this specimen.
