NO. 1210. SYXOPSIS OF NORTH AMERICAN TELLINID.E—DALL. 305 



Telllna hodegeiisis^ and may bo identical. It is said to be found in 

 Japan and China, but 1 have seen no spcciiiKMis from that rogion. 

 Dunkcr also docs not cite the species from fJai)aii, and it may bo that 

 Deshaycs's name was founded on a Galifornian specimen wrongly 

 labeled as Asiatic. 



TELLINA (PERONIDIA) SANTAROS^ Dall, igoo. 



Santa liosa, San Miguel, and Santa Barl)ara Islands, of the Santa 

 Barbara group, California. 



This form, which may prove a special race of TelUna hodegensis, is 

 thinner. Hatter, less Hexuous behind, with the part of the disk in front 

 of the umbonal ridge of the left valve with the concentric sculpture 

 suddenly obsolete; the color whiter, with translucent venulations of a 

 radial tendency. Adult specimens look very different from Telllna 

 Ijodtycnsl)^ of the same size. 



Genus STRIGILLA Turton. 

 STRIGILLA FUCATA Gould, 1851. 



Lower California, south to Panama. 



Strlgilla costtdifera Morch, 1861; StrigiUa carnaria Carpenter, 1856, 

 not Liniucus, 1758; Sf/'igt'lla m hi lata Carpenter, 1856, not of Gould, 

 are s^'nonymous. In color, in minuter details of sculpture, and in the 

 presence or absence of a smooth radial streak on one or both valves, 

 these shells are notably inconstant. Nuttall (erroneously?) reported 

 this species from Santa Barbara, California. A posterior thickened 

 ray or two, internally, are often developed. 



STRIGILLA SINCERA Hanley, 1844. 



Cape St. Lucas to Panama. 



Sfi-hjilla dlsjuncta Carpenter, 1856, is said b}" Carpenter (1861) to be 

 identical. The species is posteriorly produced, white, and grows to a 

 large size. 



STRIGILLA CICERCULA Philippi, 1846. 



Gulf of California to Panama. 



Strigllla imtga Morch, 1861. Strlgilla iiiterrupta ^lorch, 1861, Stri- 

 giUa ervilia Philippi, 1816, StrigiUa dichotorna Philippi, 1846, and 

 Strlgilla insifoTniis Phili]Dpi, 1816, ex parte, not of Linnteus, 1758, 

 are synonymous. This form is the analogue on the Pacific coast of 

 the West Indian StrlgUla jjlslforinlx. 



STRIGILLA LENTICULA Philippi, 1846. 



Cape St. Lucas to Central America. 



Strigllla serrata Morch, 1861, seems identical. This species is the
