552 REPORT 1863. 



375. CJiiton pulchellm, along with Ischnochiton Elennms, and ?vor. expressus. 



376. Chiton Stokesii. Sent as C. patulus by Mr. Cuming. 

 377-379. Probably vars. of Anomia tennis (non lampe). 



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

 as O. Panamensis. 



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



Columbiensis. 



383. Ostrea, sp. ind. c?, more like the Gulf Mex. shells than O. Virginica, M. 212. 



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



phila, M. 214. 



386. Spondylus, s^.jPlicatulapenicittata, M. 210. 

 393, 394. Perna, sp. a, 6, = 7. Chemnitzianum. The Jamaica conspecific shells are 



labelled " bicolor, Ad." 

 396. Pm>m tuberculosa, C. B. Ad., probably = P. maura, jun. 



398. Lithodomus, sp., includes Z. aristatus, M. 176, Z. attenuatus, M. 173, and 



Z. ?plumula, jun., M. 175. 



399. Modiola semifusca, C. B. Ad.,=7J/. Braziliensis, 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, J/ytf. multiformis [= Adam- 

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



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



M. 121 b. 



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



407. Chama echinata. C. B. Ad., ? Mexicana, ]\m.,+Buddiana, jun 

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



419. Arcapholadiformis Sarbatiagradata, var. 

 422. Area shnilis, scarcely a variety of A. tubercidosa, 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 H. media. 



435. Venus ?amathusia, C. B. A.d., = Anomalocardia subimbricata, M. 113 



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

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



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



form of Crassatetta. 



451. Cyrena maritima. ll The discovery of Cyrena 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. Donax 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^Z). carinatus, Mus. Cum. hodie, and type, teste Hanl.,=i>. culminahis, 



M. 72. 



459. Tel/ina cognata Psammobia casta, Eve., teste Cuming. 

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



doubtless due to an accidental error in labelling. No. 476 is th" e same 



species, dead. 



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

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



Indian specimens. 

 473. 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 Heterodonax bimaculatus. The Panamic shells resemble 



the Lower Califorman, which are Psammobia Paci/ica, Conr. 



477. Petricola cognata. Perfect specimens are P. pholadiformis, teste Cum 



478. Saxicava tennis, Sby., C. B. Ad., H. and A. Ad.,='Petricola tennis, 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. 43. 



483. Cumingia, sp. c, = M. 45, and, if not described, may stand as C. Adamsil 



484. Cuminyia, sp. rf, = M. tablet 107, p. 31.
