occurs on the outer margin, nearly parallel with the peristome, its 

 upper termination bent slightly forward ; on the parietal wall is 

 a low bifurcated entering fold, its lower arm terminating close to tlie 

 peristome, descending abruptly, its upper arm shorter, descending 

 gradually. Diam. maj. 21, min. I8*5nim. ; alt. 10 ram.

Type in the British Museum, presented by Major A. J. Peile, R.A. 



The new species is nearest to P. rexans, but is smaller and more 

 distinctly and coarsely granulated, almost beaded. It diifers further 

 in having a white peristome, in having the upper fold parallel with, 

 instead of transverse to, the peristome, in the fold on the basal margin 

 being oblique, in the junction of the basal and outer margins being 

 more acute, in tlie straight parietal margin, and finally m the bifurcate 

 entering parietal fold. The aperture in sliape resembles more that 

 of Lahyrinthus triplicata^ ^lart. 



Neocyclotus Peilei, n.sp. 



Shell somewhat narrowly umbilicated, depressed turbinate, more 

 or less striated transversely, the striae being intersected by otber 

 striae descending obliquely forward, thus forming coarse granules 



arranged in quincunx, except in a few scattered places where 

 a portion of either set of striae is continuous, in some instances even 

 forming zigzag lines, while near the peristome the oblique striae 

 tend to disappear and the granules become obsolete. Whorls 5,
