Bulla clausa n. s. 



Shell small, subtranslucent, solid, of the form of B. solida (Gmelin, non 

 Brugiere), pale yellowish brown verging toward salmon color in the darkest 

 parts; surface polished, with well marked incremental lines and extremely fine 

 microscopic wavy spiral striae over the whole surface. Aperture as long as the 

 shell; wide anteriorly with a strongly arched callous white columella having a 

 groove behind it and a thin callus on the body. Apex imperforate, meeting 

 the descending outer lip with hardly a dimple. Max. Ion. 11.5; max. lat. 

 7.75 mm. 



Habitat. Florida, collector unknown, U. S. Nat. Museum, No. 55188. 



This is the only shell, except the abyssal species like eburnea and abyssicola, 

 having the solidity and characteristic form of typical Bulla which I have found 

 without an apical perforation or distinct pattern of coloration, yet it seems too 

 heavy and porcellanous to be referred to Haminea. It was probably collected 

 by Stimpson. 



Genus HAMINEA Leach. 



Haminea succinea Conrad. 



Bulla succinea Conrad, Proc. Acad. Nat. Sci. Phila., III. p. 26, pi. i. fig. 5, 1845 ; 

 Dall, Hemphill's Shells, p. 324, 1883. 



This species resembles Haminea Guildingi Sowerby, but is smaller, much 

 more slender, and whiter. It is common in shallow water on the coast of 

 Florida. A single specimen was dredged by the Blake at Station 247, off 

 Grenada, in 170 fms., ooze, bottom temperature 53°. 5 F. 



This form is quite distinct from Haminea solitaria Say. The other species 

 belonging to the region are H. antillarum Orb. (4- H. cerina Mke. 1853, and 

 H. guadelupensis Sby. in Reeve, Conch. Iconica) ; H. Guildingi Swains. (? = 

 elegans. Gray in Suppl. Wood, Index Testae); and H. Pelitii Orb. (+ H. glabra 

 A. Ad. in Thes. Conch.). 



Family PHILINID^E. 



Genus PHILINE Ascanius. 



Philine infundibulum n. s. 



In the multiplicity of species of Philine this one is best described by a com- 

 parative diagnosis. The soft parts externally are whitish, and resemble P. quad- 

 rata and P. finmarchica as figured by G. O. Sars.* It is nearest P. quadrata 

 so far as shell characters go, and belongs to the group of species which have
