Streptostele (Rafraya) taylori (Gibbons). 

 (Pl.'XIV. fig. 26.) 



As this little-known species has never been satisfactorily 

 illustrated, I puhlisli a figure of the type, which is in the 

 British Museum. The dentition consists of a blunt, sinuous, 

 parietal i)lait hardly visil)le in the figure, developing into a 

 sharp point a little within the aperture, and a marked })ro- 

 tuherance on the incurvation of the outer lip; the shell is 

 4*8 mm. long. 



Subgenus Gbaptostele, Pilsbry, 1919. 

 Minute shells with faint microscopic spiral sculpture. 



Streptostele {Graptostele) candelula, sp. n. 

 (PI. XIV. fig. 20.) 



Shell very small, shortly acieular, imperforate, thin, 

 smooth, glossy, nearly transparent, lacteous. Spire pro- 

 duced, sides tapering extremely gradually, apex broadly 

 rounded. Whorls 7, nearly flat, 2nd and 3rd about equal, 

 remainder very slowly increasing; all are sparsely, faintly, 

 microscopically punctate, practically devoid of transverse 

 sculpture with the exception of an occasional nearly straight 

 and vertical groAvth-line, and showing traces throughout, 

 under the microscope, of extremely faint, close, flat, spiral 

 striation of somewhat irregular prominence ; suture simple, 

 shallow, narrowly margined below. Aperture squarely piri- 

 form, broadened and rather flattened at the base ; peristome 

 simple but by no means thin ; outer lip receding infiiiitesi- 

 mally just below the suture and then advancing slightly 

 before receding markedly to the base ; columella slighlly 

 concave, margin adnately thickened, callus and dentition 

 none. 



Long. 4*1, lat. 1"2 ; last whorl IQ mm.

The type appears to be mature and, from its faint spiral 

 sculpture, to belong to Pilsbry's subgenus Graptostele. It 

 is easily distinguishable from the young of Rajf'ruya clara 

 through lacking any of the transverse striation, which shows 

 clearly just below the suture in that species.
