146 AGARDHIA. 



but possesses 10 whorls, the first eight of which are even more 

 cylindrical 'than in the type form, and more compressed, the 

 last two being in proportion stouter and more convex, im- 

 parting to the spire a remarkably emaciated appearance. 



"Types of the variety and subvariety are in the Indian 

 Museum, Calcutta, also in collections of M. M. Bourguignat 

 and Coombe Williams" (Nevill).

' ' This I for some time considered a distinct species ; at any 

 rate it is a well-marked, constant variety. It was not rare, 

 in deposit B only, and often in such perfect preservation that 

 it looked as if the animal had only just been extracted. Spire 

 slightly convex, much like that of var. plagiostoma, but more 

 pupiform, that is more tumidly swollen, not so attenuately 

 contracted. Whorls 8 to 9, the last two proportionally more 

 swollen and convex, the last not compressed at its base (in 

 this unlike all the preceding), very translucid, so much that 

 the columella can be traced sometimes nearly to the apex; 

 smooth, shining, no trace of the oblique sculpture character- 

 istic of the preceding ; the aperture is not unlike that of var. 

 plagiostoma, though less contracted, equally oblong, as broad 

 below as above — that is with the margins parallel; the pari- 

 etal fold considerably less vertical than in the type form; 

 the columellar one similarly straightly transverse, the palatal 

 ones, as seen through the back of the last whorl, seem to me 

 much the same ; the outer margin is less straight than in any 

 of the preceding forms — that is to say, is more pinched in at 

 the callous tooth and is consequently more arcuate above and 

 below; the columellar one considerably less oblique, above 

 scarcely twisted, at base more gradually rounded. Long. 4%, 

 diam. (vix), l 1 /^ mm.

"This form, I believe, will eventually prove to be distinct 

 from its allies found on the other side of the headland, as is 

 the case with species of Clausilia, and Powiatias; as, however, 

 I only found, in deposit D, a single specimen (the preceding 

 forms not being found there at all), I do not feel justified at 

 present in describing it as a distinct species. 



A short, tumid, pupiform variety, with only 7 whorls, more 

 convex and increasing more rapidly than in any of the pre-
