 very inadequate.

TELLINIDAE. 



TeUina sp. undet. 



? Tellina pimicea Born, Gabb. Trans. Amer. Philos. Soc, xv, 1873, p. 248. 

 An imperfect internal cast in a hard rock, no. 2788, resembles this 

 species in outline but is more convex. It was not labelled, but may 

 possibly represent Gabb's T. punicea. No specimens were found 

 under that name in the collection. 



Tellina (Eurytellina) n. sp. 



A weakly grooved left valve, which has been broken into several 

 pieces and repaired, apparently belongs to an undescribed. species. 

 It is no. 3200 A. N. S. P. 



Tellina alternata Say. 



Tellina alternata Say, Gabb, Ti'ans. Amer. Philos. Soc, xv, p. 248. 

 There is a set of T. alternata in the collection labelled ''U. S." 

 possibly from Santo Domingo or Costa Rica, but without Gabb's 

 MS. label. We cannot, therefore, confirm or reject Gabb's record. 

 This and T. punicea are the only species mentioned bj^ Gabb which 

 we have not been able to trace in the collection. 



Tellina minuta Gabb. Text-fig. 46a, b. 



Tellina (Peronceoderma) minuta Gabb, Trans. Amer. Philos. Soc, xv, 1873, 

 p. 249. 



The shape is subcircular rather than "suboval". Left valve 

 without lateral teeth, and a little plumper than the right. Exter- 

 nally there are very fine, evenly spaced concentric lines with flat 

 intervals, much as in T. alternata except that the sculpture is very 

 fiat and superficial. It is quite thin, and the internal impressions 

 are faint. 



Length 5.5, alt. 4.75 mm. 



Type no. 2789 A. N. S. P.
