Centr. Am. [The Pacific shells should rank with species 22, if sup- 
posed distinct. The fig. is 24, not 23.] 
. Dione exspinata, Rve. Centr. Am. Distinct, if the others are; like seméla- 
mellosa, without spines. [Appears to be C. rosea,jun. The fig. is 23, 
not 24, |} 
Dione circinata, Born. Mazatlan, Mus. Cum. [without authority.]=V. 
28, a, b, rubra, Gmel.,+ V. Guineensis, Gmel.,+ C. alternata, Brod. [f. 28 repre- 
sents alternata; the other figures appear to be from West Indian spe- 
cimens, though that ancient locality is not mentioned. Several of the 
reputed West Coast shells are, however, of the typical form and colour. | 
Dione unicolor, Sby.,= Chione badia, Gray, = Cyth. ligula, Anton. W.Columbia. 
Dione prora, Cony, ‘Cape St. Lucas, Xantus, California; Carpenter.” 
[A very distinct form among the thin inflated species ; only yet found at 
the Sandwich Is., vy. no. 45. 
. “(Mus. Smithsonian Institute of N. America.) This shell, from Cape St. 
Lucas, Xantus, California, proves to be the Dione prora (Cytherea prora, 
Conr.) of our preceding plate.” [Mr. Sowerby’s figure well represents 
the unique specimen from Cape St. Lucas, which was taken alive by Mz. 
Xantus. The quotations in Conch. Ic. would lead to the inference that 
“ Xantus ” was regarded as that part of “ California” in which Cape St. 
Lucas is situated. Both the external and internal characters require 
that a separate name be given to the shell, which stands as Callista pol- 
hearis, Annals Nat. Hist. vol. xiii. p. 312.) 
Cytherea consanguinea, C. B. Ad. Mus. Cum. Apparently a small spe- 
cimen of a variety of C./eta. [Panama, Differs from C. deta in inter- 
nal characters. | 
. Dione pannosa, Sby.,= Cytherea lutea, Koch,+ Callista puella, Cpr. Chili, 
Peru, Mazatlan. [No authorityfor Mazatlan. The name pwella given 
to the Cape St. Lucas specimens was intended as varietal ; although 
Mr. Cuming regards the Peruvian and Peninsular forms as distinct. It 
is not known along the Central American coast. 
» Circe nummulina, Lam. “Central America.” [Probably not from the 
American seas. Admiral Sir E. Belcher is, however, confident that he 
dredged many well-known E. Indian forms in deep water, off San Blas. } 
. Cytherea. In this genus are grouped the Trigone ; besides the typical species, 
= Meretriz, Gray. 
. Cytherea crassatelloides, Conr. “ Bay of California.” [Not known geogra- 
phically. The shell is not found in the Gulf, being a most characteristic 
Californian species. San Francisco, 8. Diego, &e. 
. Cytherea radiata, Sby., + C. gracilior, Sby.,= V. Salangensis, D’Orb.= T. By- 
ronensis, Gray. Salango and Xipixapi, 9 fms. sandy mud, Cuming. 
. Cytherea nitidula, Lam. Mediterranean. [The figures and descriptions of 
Sby. and Rve. well represent specimens from Cape St. Lucas, Xantus. 
Perhaps not identical with Lam.’s species. | 
. Tapes grata, Desh. Philippines. [May stand as 7. Deshayesit, if it be con- 
ceded that Say’s V. grata ranks best with Tapes. | 
. Solarium granulatum, Lam. Mexico. 
. Solarium verrucosum, Phil. W. Indies. ?=/S. granulatum, var. 
. Solarium placentula, {[ Rve.=placentale,| Hds. Bay Magdalena, 7 fms., Belcher. 
. Solarium quadriceps, Hds. Panama. Young state of same type as sp. 7 and 8, 
“from same locality (Pan., Mex., W.I.),” but grows much larger. [The 
Texan shells in Mus. Smiths. are as large as those from Cape St. Lucas : 
the variations on each coast are coordinate. |
