544A. REPORT— 1868. 
98. Callista alternata has a very different aspect from the ordinary C. circinata ; but 
several of the Pacific shells affiliate more naturally to the West Indian form. 
99. C. affinis, C. tortuosa, and C, concinna appear to be one species. 
100, Sir E. Belcher is confident that he dredged C. petechiulis, in deep water, off S. 
Blas. He has the same confidence in regard to some of the East Indian 
Circes. At this distance of time, a written locality-ticket would have had 
more authority. 
105. The hinge proves that this species is distinct from the true V. crenifera, Sby. 
It has been named V. sugillata by Rve., Conch. Ic. sp. 48. It was also 
brought by Kellett and Wood, and is allied to V. pulicaria. 
110. Among the Panama varieties of this very variable species is Venus fuscolineata. 
T. grata takes the place of the Californian 7. staminea, which is sometimes 
erroneously given as a synonym, and is not straminea, as often quoted. 
116. It appears that Gouldia (Thetis, C. B. Ad., olim, non Sby. nec H. & A. Ad.) is 
congeneric with “ Circe” minima, not with the Astartids. Prof. Adams’s 
fresh specimens of his G. Pacifica prove to have the Crassatelloid internal 
ligament, and represent one of the many remarkable forms of that group. 
117. Fresh specimens of G. varians, from Cape St. Lucas, have also the internal 
ligament, and must rank under Crassatel/a until that genus has been naturally 
divided. 
118. Lazaria Californica. A well-marked group of species from the West Coast. 
121. The purple and orange specimens, here treated as the adolescent state of Chama 
Mexicana, ave certainly the Ch. echinata of collections, and may possibly 
prove a distinct species. A large series sent from Socoro Is. by Mr. Xantus 
confirms this view ; but all the specimens seen are decorticated or incrusted. 
121. This is the Chama Buddiana of C. B. Ad., and probably distinct. 
134. The specimens of Cardiwm graniferum in Mus. Cum., from St. Thomas, W. L, 
appear exactly identical. 
136. The specimens from the Pacific coast, some of which are of very large size, 
have generally a red tinge round the inner margin; as have also the Fiji 
specimens brought by the U. 8. Expl. Exp. In other respects they exactly 
accord with the W. Indian. The Pacific shells are generally called C. 
exasperata, Rve., a name first given to the rough Caribbean variety from 
Honduras, &e. 
187. Codakia punctata. This shell also, brought by the U. S. Expl. Exp. from the 
Fiji Is., is found sparingly along the American shores, and has the same 
coloured margin. 
142. May possibly prove identical with ZL. bella, Conr., S. Diego. 
150. The Fein orbella of Gould, =Spherella tumida, Conv., Ms., is the northern 
form; uniformly larger and smoother than Diplodonta semiaspera. This 
last is fully confirmed from both oceans. 
152. “ Felania” serricata appears congeneric with Miltha, H. & A. Ad.,= Mittrea, 
Gray, the type of which (JL Childrenc) is a Gulf species. 
154. Lasea rubra. Mr. J. G. Jeffreys does not consider the Brit. Mus. specimen 
identical with the British. The Mediterranean specimens are much more 
unlike. A colony of fresh shells from a burrow at Cape St. Lucas, when 
examined, under the microscope, side by side with Ifracombe specimens, did 
not present even varietal differences. The species also appears on the Cali- 
fornian and Japan coasts. Similar and perhaps conspecific forms are 
found on most coasts: among them is Poronia Petitiana, Chen. Conch. Ill. 
p. 2, pl. 1. f. 2; Callao, not rare, Petit. ; 
156. For this species, corbuloides, and other angular forms, the name Bornia may 
be revived in a restricted sense. (A. Ad.) 
157, 158. Mr. A. Adams, who is about to make the Kelliads a special study, thinks 
that these intermediate forms would rank better with Montacuta or Tellimya. 
166. This is almost certainly = Anodonta glauca, Val. 
168. Dr. Dunker renamed this shell /. Adamsianus, P. Z.S. Nov. 1856. 
177. The subgenus Adula may be enlarged to include this and other nostling 
? Lithophagi, which often adhere by byssus, like Modiola. 
178. Liosolenus is quite distinct from Mytilimeria, which appears simply an aber- 
rant form of Zyonsia. Other “ Lithophagi” probably rank with it.
