NO. 2207. WEST AMERICAN MELANELLID MOLLUSKS—BARTSCH. 345 



I have seen the following additional specimens: 



STROMBIFORMIS BURRAGEI, new species. 



Plate 47, fig. 5. 



Shell very small, elongate-conic, polished, light yellow, with the 

 tip light brown and with a broad brown band on the middle of the 

 base. Early whorls well rounded, separated by a constricted suture. 

 The succeeding turns weakly rounded, with a very feebly impressed 

 suture, marked by exceedingly fine Unes of growth only. Periphery 

 obscurely angulated. Base rather short, well rounded. Aperture 

 broadly oval; posterior angle obtuse; outer lip thin; inner lip short, 

 decidedly curved, reflected and appressed to the base posteriorly; 

 parietal wall covered by a thick callus. 



The type (Cat. No. 267582, U.S.N.M.) was dredged in 3 fathoms at 

 the head of Concepcion Bay, Gulf of California, by the United States 

 Bureau of Fisheries steamer Albatross on mud bottom. It has lost the 

 first turn; the eight remaining measure — ^length, 2.7 mm.; diameter, 

 0.9 mm.
