308. Lithixhmm, .«p., includes Z. aristatua, M. 1713, Z. attenuatus, M. 173, and 



Z. 'fplamula, j{m., M. 175. 



309. Modiolti Kvmifitsca, C. B. Ad., = .V: i?ra=j7»en«s, M. 171. More like the Atlantic 



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



Zealand, is pronounced con.specific by Mr. Cuminp.

 432. C'ardiuni planicoMutum, V. B. Ad., may be a worn valve of Hemicardia hian- 



ffulata, but more resembles a ballast specimen of the W. Indian 7/. media,

450. Gmddia Pacijica, M. 110^ does not belong to the Professor's genus, but is a 



form of Crassatella. 



451. Cxfrena maritima. " The discoverv of Cyrente in brackish water is a fact of 



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

 466. Teliina felix. The affiliation of this shell to Striyilla fucata, Gld., ]\IS., was 



doubtless due to an accidental eiTor in labelling. No. 47(3 is the same 



species, dead. 

 468. Teliina pudla. Resembles T. felix, not ??puella, M. 59. 

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



Indian specimens. 

 473. Teliina vicina, CR. AA.,=versicolor, C. B. Ad., MS. on label. Larger than 



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



are varieties of lletcrodonax bimaadatus. The Panamic shells resemble 



the Lower Califomian, which are Psainviubia Pacifica, Conr. 



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



478. Saxicara tenuis, Shy., C. B. Ad., H. and A. Ad., = 'Petncola tenuis, H. and A.
