left figures) or losing very few whorls (two right figs.) in the adult 

 stage; widest at the upper third; white. Whorls 2526, rather 

 strongly convex, the first four smooth, the rest regularly and closely 

 striate, the striae nearly straight, strongly oblique, about as wide as 

 the intervals. Last half whoi 1 free and deeply descending, sharply 

 striate. The free part is cylindrical and forms about one-fifth of the 

 total length of the shell. Aperture circular, oblique, with broadly 

 flaring, trumpet-like peristome. Internal axis very slender and 

 gyrate.

This charming species is related to B. brooksiana, but differs by 

 the less swollen shape, more numerous whorls and shorter " neck " 

 of the last. Moreover, the last whorl is cylindrical in U. torreana, 

 but in U. brooksiana it has a conspicuous basal keel. Specimens of 

 U. brooksiana are figured, pi. I, fig. 5, for comparison with the new 

 species. By the want of a basal keel and the convex whorls, B. 

 torreana is more nearly related to B. turcasiana, a far smaller 

 species. Named in honor of my friend Dr. C. de la Torre. 



The figured types have been deposited in the collection of the 

 Academy of Natural Sciences.

BRACHYPODELLA (GYRAXIS) RAMSDENT, n. sp. PI. I, fig. 2. 



The shell is very slender, the greatest diameter contained 12 or 13 

 times in the length, whitish, slightly shining, widest at about the 

 upper fourth, composed of about 25 whorls, adult shells usually hav- 

 ing lost a few. The whorls are convex, and the last five or six have 

 a rounded ridge (or basal carina) above the suture, and a slight con- 

 cavity above the ridge. The last half whorl is free and descends 

 spirally in a long " neck," the basal carina prominent on the upper 

 half of the neck, but gradually disappearing, leaving it nearly cylin- 

 drical near the aperture, which is triangular-rounded, oblique, and 

 very small. Sculpture of rather irregular, very oblique striae ; the
