Mr. W. G. Mazyck. of Charleston. South Carolina, on Sullivans Island. 

 Charleston Harbor. The species occurs in the Antilles, where it has 

 received the name of TeJlina schrammi from Recluz, but a compari- 

 son with specimens from the Gulf of California does not show an}' 

 distinctive characters.

Shell solid, white, rounded, triangular; the anterior end a little 

 longer, rounded in front, the posterior shorter, slighth' Hexuous. 

 bluntlv pointed; surface sculptured with rather distant, very thin, 

 sharp, little elevated lamella?, the interspatial surface hnelv radially stri-

Ti/j)c.—^o. 91465, U.S.N.M.; collected at Bermuda by the late 

 Dr. G. Brown Goode. 



The nearest ally of this species, and which has probably often been 

 confounded with it, is the shell we have identified with the Tdlhia 

 mera of Say, from which it difiers as we have stated in a previous note 

 in this paper (p. 2!M)). 



TELLINA (ANGULUS) FLAGELLUM new species. 

 (Plate 11, fig. 6.) 



Shell small, polished, white, yellowish or rosaceous, with a single 

 dark red ray extending backward from the umbo parallel with the 

 umbonal ridge; valves moderately convex, elongated, pointed, and 

 slightly flexuous Ijehind, sculptured with fine regular concentric 

 grooves with slightly wider interspaces; hinge of Angidus^ the approx- 

 imate lateral broad and strong; pallial sinus long, rounded behind, not 

 reaching the anterior adductor scar, and wholly confluent below. 

 Lon. 9, alt. 5, diam. 3 mm. 



Ty2)e.—Ko. 108.531. U.S.N.M.; dredged by the U. S. Fish Commis- 

 sion, SE. of Cape San Koque, Brazil, in 20 fathoms; bottom tempera- 

 ture 79° F. , at station 2758. 



A species, externalh' very similar. fro»i Port Jackson, Australia, 

 was described l)y Sowerby in 1868, under the name of TeUino miifas- 

 ciata, but he states that it has no lateral teeth. The present species is
