375. CJiiton puhMlus, along with IschnocUton Elenemis, and Pvar. expressus. 

 37G. Chiton Stokesii. Sent as C. paiukis by Mr. Cuming. 

 377-.379. Probably vara, of An mia tenuis (nou lampe). 



380, 381. Ostrea, sp. ind. a and b, a peculiar corrugated species, wHcli may stand 

 as 0. Panamensis. 



382. Ostrea, sp. ind. e, resembles O. rufa, Gld., MS. (not Lam. in Deless.), not 



C'olumhiensis. 



383. Ostrea, sp. ind. d, more like the Gulf Hex. shells than O. Virginica, M. 212. 



384. Osirea, sp. ind. e, may stand as 0. amara. The " small var." is O. concha- 



phila, M. 214. 

 380. Spondylus, s^., = Plicatula penicittata, M. 210. 

 393, 394. Perraa, sp. a, b, = I. Chemnitzianwn. The Jamaica conspecific shells are 



labelled '' hicolor, Ad." 

 396. Pinna tuberculosa, 0. B. Ad., probably=P. maura, jun. 



398. Lithodomus, sp., includes Z. aristatits, M. 176, i. attentiatm, M. 173, and 



i, ?plamula, jun., M. 175. 



399. Modiola semifusca, CB. A.A., = M. Braziliensis,M. 171. More like the Atlantic 



shells than are those fi'om Gulf Cal. A specimen, undoubtedly from N. 

 Zealand, is pronounced conspecific by Mr. Cuming. 

 400-404. Modiola, sp. ind , contains M. capax, M. 170, Myt. multiformis \_=Adam- 

 sianus, Dkr.], M. 168, several vars., and Adula cinnamomea, var. M. 177. 



405. Chama Buddiana (in poor condition) = Ch. ( ffrondosa, var.) fornicata, 



M, 121 h. 



406. Chama ?corrugata, small valve ; large one ? = Cli. Mexicana, reversed. 



407. Chama echinata, C. B. Ad., ?=Mexicana, ^xni,,-\- Buddiana, jun 

 414. Area ?amcidoides, C. B. Ad., appears a young Scapharca. 



419. Area pholadiformis=Barbatia gradata, var. 

 422. Area similis, scarcely a variety of A. tuberculosa, no. 425. 

 432. Cardium planicostatum, C. B. Ad., may be a worn valve of Hemicardia bian- 

 gulata, but more resembles a ballast specimen of the W. Indian S. media. 



435. Vemis ?amathusia, C. B. Ad.., = Ano}7ialocardia subimbricata, M, 113 



436. Venus discors= Tapes grata, M. 110, var., + 21 histrionica, M. 109. 

 442. Venus, sp. b, = Chione sugillata. Eve. ( = ?erenifera, M. 105). 



450. Gouldia Pacifica, M. 116, does not belong to the Professor's genus, but is a 



form of Crassatella. 



451. Cyrena maritima. " The discovery of Cyrence in brackish water is a fact of 



some importance to geologists,, which was duly appreciated by D'Orb " (T. 

 Prime, in Ann. Lye. N. Y. 1861, p. 314.) 

 457. Bonax rostratus, C. B. Ad. (non Gld., MS., and from it Cpr. in M. Appendix, 

 p. 549), teste type-valve=D. carinatus, Mus. Cum. olim, and from it M. 71 • 

 non^D. carinatus, Mus. Cum. hodie, and type, teste Haul.,=i). culminaius, 



459. Tellina cognata= Psammobia casta. Eve., teste Cumino'. 



465. Tellina felix. The affiliation of this shell to Strigitta fucata, Gld., MS., was 

 doubtless due to an accidental error in labelling. No. 476 is the same 

 species, dead. 



468. Tellina puella. Resembles T. felix, not ??puella, M. 59. 



471. Telliiia simulans. The type-valve exactly accords with the Professor's W 

 Indian specimens. 



473. Tellina vicina,C. B. Aa., = ve,-sicolor, C. B. Ad., MS. on label. Larger thnn 

 most W. Indian specimens, which exactly accord with the Acapuleans, and 

 are varieties oi Heterodmmx bimacidatus. The Panamic shells resemble 

 the Lower Oahfomian, which are Psammobia Pacifica, Conr 



4/7. Petrtcola cognata. Perfect specimens are P. pholadiformis, teste Cum 



478. Saxieava tenuis Shy. C. B^Ad., H. and A. AA., = Petricola tenuis, H. and A. 



A-7a .s^ -^ °- PP- '^3-f"' ^^ ^^,«'^^ =^ccords with the latter genus.
