330 LAND AND FRESHWATER 



given off at a short distance from the head of tlie penis. The 

 Bpermatheca is a globose sac on a long thin duct. The dart-sac is 

 globular, short, sessile near the generative aperture, and in trans- 

 mitted light there was an indistinct appearance of a short pointed 

 dart within it (fig. 1 e). The radula (fig. 1 h) was not got out in 

 a perfect state (I had only one specimen to deal with), so only the 

 central and admedian were left, all the marginals had gone. The 

 centre tooth is very small and simple, no side cusps ; the admedian 

 present a bluntly rounded inner tooth with a very minute cusp on 

 the outer side very similar to Catludca 2r)jrrhozona, Phil., Pilsbry, 

 Man. Conch, pi. 65. fig. 7. The jaw (fig. 1 //) is arched and made 

 lip of a great number of elongate narrow plates, about 20, twice 

 as many as in jiijrrhozona, Man. Conch, pi. 65. fig. 8.

Nevill, Haud-list, 1878, p. 66 (under Patula), recorded it from 

 Simla and Murree. Two specimens from Chur, near Simla, coll. 

 P. Stoliczka (this is the Chor Mountain) ; in his emended copy he 

 distinguishes these as sub-var. sinistrorsa, it may possibly be a 

 distinct species, " These are both sinistral specimens. Hutton in 

 his original description records the strange tendency of this form 

 to become reversed ; it is interesting that Dr. Stoliczka, after so 

 many years, was able to confirm the observation ! " On the other 

 hand I collected a considerable number at Mussoorie, yet have never 

 seen a sinistral example — the same applies to the collection lately 

 received from that hill-station. 



Theobald, J. A. S. P. 1881, p. 47 {Valhnin), records it from 

 Tundiani, near Murree, as not rare. 



For some 30 years I have been in hopes of getting living speci- 

 mens or specimens preserved in spirit of this small species, of 

 ■which the generic position was quite unknown. It is plentiful on 

 the limestone rocks at Mussoorie during the rains, in certain 

 localities, and I am at last greatly indebted to my brother-in-law, 

 Major Stratford W. Robinson, P. A., who being there last summer 

 (U)ll) responded to my request to look for the smaller species of 

 shells. They arrived folded up in blotting-paper, and I was in 

 hopes some of thom might still be alive — however, there was no 

 result after placing them in water in a warm place. I then put 

 them to soak, and although the animals softened out I could not 

 find a radula. Finally, however, in one example after it had been 

 six weeks in water in a glass tul)e, I was able to get both radula 

 and jaw, and am able to give the following description and suggest 

 its relationship.
