DESCKIPTIONS OF TWO NEW SPECIES OF SYNAPTERPES. 

 By Hugh C. Fulton. 



Read IZlh March, 1908. 

 Synaptekpes (Zoniferella) bicingulatus, n.sp. Fig. 3. 



Shell imperforate, subfusiform, glossy, thin, dark green, with two 

 whitish spiral bands on body-whorl, the upper one ascending the 

 spire just above the suture; apex smooth, obtuse, yello wish- white ; 

 whorls 6^, slightly convex, slowly increasing, last about half the 

 length of the whole shell, lightly striatulate, somewhat puckered 

 at the suture; aperture subovate, outer bands showing through; 

 peristome quite thin ; columella subtruncate, white, slightly expanded 

 in the middle, entering deeply. Alt. 20, maj. diam. 8 mm. 



Hab. — Ecuador. 



Judging from the figure and description (T have not seen a specimen), 

 this species is near S. alhohalteatus, Dkr., but readily distinguished 

 by its different form and banding. 



The dark-green in the type-specimen is replaced in another by 

 a yellowish-brown colour. 



Synapterpes (Zoniferella ?) PiLSBRYi, n.sp. Figs. 1, 2. 



Shell narrowly umbilicate, rather thin, glossy, areuately striated; 

 lower whorls covered with narrow spiral bands of various shades of 

 green alternating with several conspicuous narrow whitish bands ; 

 apex smooth, whitish, obtuse ; whorls nearly 8, moderately convex ; 



'X»>^' 



aperture subovate, outer bands visible within ; peristome thin ; 

 columella almost straight, whitish, moderately thickened, and very 

 slightly expanding up to the point of insertion. Alt. 26, maj. diam. 

 11 mm. 



E'ah. — El Congo, Quilachao, Cauca, Colombia. (Messrs. Paine & 

 Brinkley.) 



This striking new species is closely allied to the Zoniferella group 

 of species placed under the genus Synapterpes, Pils. (=: Oxycheilus, 

 Albers, and Orphnus, auct.), in Tryon's Man. of Conch., vol. xviii 

 (1906), p. 227.
