93. Callisfa alternata has a very different aspect from the ordinary C. circinata : Tint 

 several of the Pacific s'.k-Us atiiliate more naturally to the West ludiantLTiu. 

 99. C. affinis, C. tortuosa, and C. cancinna appear to be one species. 



100. Sir E. Belcher is confident that he dred^^ed C. pekchiulis, in deep water, ofi S. 

 Bla'9. 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. a-enifera, Sby. 

 It has been named V. siigilUda by Rve., Conch. Ic. sp. 43. 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 fiiscnlineata. 

 T. grata takes the place of the Califomian T. staminea, which is .sometimes 

 erroneously given as a synonym, and is not stramuiea, as often quoted. 



113. It appears that GoulJia (^Thetis, C. B. Ad., olim, non Sby. nee II. & A. Ad.) is 

 congeneric with '■ Circe'' minimn, not with the Astartids. Prof. Adams's 

 frush 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. variam, from Cape St. Lucas, have also the internal 

 ligament, and must rank under Crassatella until that genus has been natrntdly 

 divided. 



lis. Lazaria CaUfortiica. A well-marked group of species from the West Coast. 



\2l. The purple and orange specimens, here treated as the adolescent state of Chuiua 

 3fexCcana, are certainly the Ch. echinata of collections, and may pos.-iibly 

 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. 



1216. This is the Chama Baddiana of C. B. Ad., and probably distinct. 



1-34. The specimens of Cardium (jnmiferum in Mus. Cum., from St. Thomas, W. I., 

 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. S. 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, &c. 



137. Codaliia 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 L. hella, Conr., S. Diego. 



150. The Lucina orbella of Qio\AA, = Sphcerella tumida, Conr., MS., is the northern 

 form ; uniformly larger and smoother than Diplodonta semia.tpera. This 

 last is fully confirmed from both oceans. 



152. " Felania" serricata appears congeneric with 31iltha, H. Sc A.. Ad., = Jlittrea, 

 Gray, the type of which (3/. CIdldrvni) is a (iulf species. 



154. Lasea rubra. Mr. J. G. Jeflrevs does not consider tne Brit. Mus. specimen 

 identical with the British. The MediteiTanean specimens are much more 

 unlike. A colony of fre.sh shells from a buiTow at Cape St. Luciis, when 

 examined, under the microscope, side by side with Ilfraconibe .specimens, did 

 not present even varietal ditierence". The species also appears on the Cali- 

 fornian and Japan coasts. Similar and perhaps conspecific forms are 

 found on most coa.sts : among them is Poronia Petitiana, Chen. Conch. 111. 

 p. 2, pi. I. 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 TvlUnnja 

 166. This is almost certainly = -4«0f/oH^rt glauca, Val. 

 168. Dr. Dunker renamed this shell M. Aduniiianm, P. Zi S. Nov. 1856. 



177. The subgenus Adula may be enlarged to include this and other nestling 



? Lithophaf/i, which often adhere by byssus, like Mmliofa. 



178. Liosolemi* u amXii dis inct from Mi/filiiiieria,w\i'w]\ appears simply an aber- 



rant form of Lyonsia. Other " Lithophaiji" probably rank with it.
