 '377-^19. l\'ohAh\y V-AV&. oi Awmia tenuis (non lampe). 



380, 381. Ostrra, sp. iud. a and h, a peculiar corrugated species, which may stand 

 as O. Panamensis. . -r^ i \ 



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



Columhiensis. ^ tt- • • tit mo 



383. Ostrea, sp. ind. (7, more like the Gulf Mex. shells than O. lirgimca, M. 21J. 



384. Ostrea, sp. ind. e, may stand as O. a?«a/-a. The " small var." is O. concha- 



phila, M. 214. 

 S86. Spondi/liis, !i\x, = Plicat.uIa penicillaf a, M. 210. 

 393,394. iWna, sp. a, b, = I. Chemnitzianum. The Jamaica conspecific shells are 



labelled '' bicolor, Ad." 

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



398. Lithodomm, sp., includes L. aristatus, M. 17G, L. attemiatus, M. 173, and 



L. ?plu7mila, jun., M. 175. 



399. Modiola semifusca, C. B. Ad., = M. Braziliens{s,M. 171. More like the Atlantic 



shells than are those from 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 1= Adam- 

 siamts, Dkr.], M. 108, several vars., and Adula cinnumomea, var. M. 177. 



405. Chama Btiddiana (in poor condition) = C7t. {ffrmdosa, var.) fornicata, 



M. 121 h. 



406. Chama ?corrtigata, small valve ; large one ? = Ch. Mexicana, reversed. 



407. Chama echina'fa, C. B. Ad., ? = Mexicana, lmi.,-\-Buddiana,'ym. 

 414. Area Yavicnloides, C. B. Ad., appears a young Scajiharca. 



419. Area pholadiformis = Barbatia c/radata, var. 



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



432. Cardium pkmicostafum, C. B. Ad., may be a worn valve of Ilemicardia bian" 



rjidata, but more resemble^ a ballast specimen of the W. Indian H. media. 

 435. Venus ?amathusia, C. B. Ad., = Anojnalocardia subimbricata, M. 11-3 

 4-36. Venns diseo7-s=Tapes f/rafa, M. 110, var., + T. histrionica, M. 109. 

 442. Venns, sp. b,= Cliione nuejiUata, live. ( = ? crenifera, M. 105). 



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



form of Crassatella. 



451. Ci/rena maritima. " The discovery of Ct/rence 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. Donox rostratus, C. B. Ad. (non Gld., MS., and from it Cpr. in M. Appendix, 



p. 549), teste type-v<'ilve=Z). carinatus, Mus. Cum. olim, and from it M. 71 ; 



non D. carinatus, Mus. Cum. hodie, and type, teste Hanl., = i>. culminatus, 



M. 72. 

 459. Tellina cognata = Psanmiobia casta, Rve., teste Cuming. 

 465. Tellina felix. The alTiliation of this shell to Strigilla fucata, Gld., MS., was 



doubtless due to an accidental en-or in labelling. No. 476 is the same 



species, dead. 

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

 471. Tellina simidans. The type-valve exactly accords with the Professor's W- 



Indian specimens. 

 473. Tellina ricina, C. B. Ai., = versicoIor, C. B. Ad., MS. on label. Larger than 



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



are varieties of Jleterodonax bimaculatus. The Panamic shells resemble 



the Lower Californian, which are Psammobia Pacijica, Conr. 



477. Petricola cognata. Perfect specimens are P. j)holadifonnis, teste Cum. 



478. Saxicava tenuis, Sby., C. B. Ad., H. and A. Ad., =' Petricola tenuis, H. and A. 



Ad. Gen. pp. 349-441, and better accords with the latter genus. 

 479, 482. Cumingia coarctata = lamellosa, var. M. 42. 

 480, 481. Cumingia trigonularis, M. 4;3.
