375. Chiton pulchellus, along with Isehnochiton Elenensis, and Pyar. eapressits. 
376. Chiton Stokesit. Sent as C. patulus by Mr. Cuming. 
377-379. Probably vars. of Anomia tenis (non lampe). : 
380, 881. Ostrea, sp. ind. a and 4, a peculiar corrugated species, which may sland 
as O. Panamensis. ‘ 
382. Ostrea, sp. ind. ¢, resembles O. rufa, Gld., MS. (not Lam. in Deless.), not 
Columiiensis. ae S Ses 
383. Ostrea, sp. ind. d, more like the Gulf Mex, shells than O. 7 irginica, M. 212. 
384. Ostrea, sp. ind. e, may stand es O. amara. The “small var.” 1s O. concha- 
phila, M. 214. 
386. Spondylus, sp.,= Plicatula penicillata, M. 210. : . ; 
393, 394. Perna, sp. a, b,= 2. Chemnitzianun. The Jamaica conspecific shells are 
labelled “ beeolor, Ad.” : 
395. Pinna tuberculosa, C. B, Ad., probably=P. maura, yun. ¥ 
398. Lithodomus, sp., includes L. aristaius, M. 176, L. attenuatus, M. 175, and 
L. ?plumula, jun., M. 175. ‘ : 
309. Modiola semifusca, C. B. Ad.,= 31. Braziliensis, M. 171. More like the Atlantic 
shells than are those from Guif Cal. A specimen, undoubtedly from N. 
Zealand, is pronounced conspecific by Mr. Cuming. : . 
400-404. Modiola, sp. ind, contains M. cazaxr, M. 170, Myt. multiformis [ =Adam- 
stanus, Dix.], M. 168, several vars., and ddula einnamomea, var. M. 177. 
405. Chama Buddiana (in poor condition)= Ch. ( ?frondosa, var.) Jornicata, 
M. 121 0. 
406. Chama ?corrugata, small valve; large one P= Ch. Mexicana, reversed. 
407. Chama cechinata, C. 3, Ad., ?= Mexicana, jun.,+ Buddiana, jun. 
414. Arca Paviculoides, C. B. Ad., appears a young Scapharca. 
419, Arca pholadiformis = Darbatia gradata, vay. 
422, Arca similis, scarcely a variety of A. tubererlosa, no. 425. 
432. Cardium planicostaium, C. B. Ad., may be a worn valve of Hemicardia bian- 
qulaia, Dut more resembles a ballast specimen of the W. Indian 2. media. 
435. Venus 2amathusia, 0. B. Ad.,= Anomalocardia subimbricata, M. 115. 
436. Venus discors= Tapes grata, M. 110, var.,4+ 7. histrionica, M. 109. 
A442, Venus, sp. b,= Chione sugillata, Rve. (=Perenifera, 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 Cyrene in brackish water is a fact of 
some importance to geologisis, which was duly appreciated by D’Orb.” (T. 
Prime, in Ann. Lye. N. Y. 1861, p. 314.) 
457. Donax rostratus, C. B. Ad. (non Gld., MS., and from it Cpr.in M. Appendix, 
p- 549), teste type-valve=D. cartratus, Mus. Cum, ol’m, and from it M. 71; 
non D. carinaius, lus. Cum. hodic, and type, teste Hanl., =D. culminatus, 
M. 72. 
459. Tellina cognaia=Psammobia casta, Rve., teste Cuming. 
465. Tellina felix. The affiliation of th's shell to Strigilla 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 ??puclla, M. 59. 
471. Tellina simulans. The type-vaive exactly accords with the Professor's W. 
Indian specimens. 
A73. Tellina vicina, C. B. Ad.,=versicolor, C. B. Ad., MS. on label. Larger than 
most W. Indian specimens, which exactly accord with the Acapulcans, and 
are varieties of Lfetercdonax bimaculatus. The Panamic shells resemble 
the Lower Californian, which are Psammobia Pacifica, Conv. 
477. Petricola cognaia, Perfect specimens are P. pholadiformis, teste Cum. 
478. Saxicava tenis, Shy.. C. B. Ad., H. and A. Ad.,= Petricola tenuis, H. and A. 
Ad. Gen. pp. 349-411, and better accords with the latter genus.
