 USNM 21012; 2 smaller paratypes USNM 612315. "The examples 

 in USNM 21012 are either too large or too small, but the figure in 

 the Expedition Shells, which exaggerates the rotundity of the 

 aperture, may have been drawn from the largest one" (H. B. Baker, 

 1941, B. P. Bishop Museum Bull. 166, p. 250). 3 paratypes MCZ 

 169077 ex NYSM 268, original no. G 2625. The largest shell in 

 the NYSM 284 [268] seems to fit Gould's dimensions for Orpiella 

 casca most closely; the second biggest specimen is a Tanychlamys 

 from India; paratype MCZ 156369 ex C. B. Adams coll.; 3 paratypes 

 MCZ 161286 ex Peabody Museum, Salem, Mass.; 2 paratypes
