56 Lt.-Coloiul H. H. Godwin-Austen on the 



" This interesting form, discovered in the mountains near 

 the Bari Do-ab by J. Dojle Sniithe, Esq., F.G.S., of 

 Madhopore, and kindly eommunicated to me ])y his brother, 

 the liev. Fred. Smithe, of Churchdown, approaches more 

 nearly to the Nilgherry H. Guerini, Pfr., than to any Hima- 

 layan species. It is notable for its shorter vaulted spire, sharp 

 keel, rather open umbilicus, and sculpture. In one imperfect 

 specimen, with a higher and more rounded hive-shaped spire, 

 the keel of the penultimate whorl overhangs the anterior part 

 of the last whorl." 



We now know that //. Ouerini, Pfr., is a Thysanota in a 

 very distinct family of Land-Mollusca. The overhanging of 

 the keel of the whorl I note in these shells, and it produces 

 tlie appearance of a thread running with the suture. Theobald 

 records the finding of a large variety of this species at 

 " Aijas" (" Ajjas " on the map of Kashmir, 2 m,=:l inch), 

 in the hills east of the Walar Lake, Kashmir, measuring 

 17j X 16| X 10 mm. This shell appears to have been lost. 



The specimen Benson described measured : diam. major 

 14 mm., minor 13, axis 7 ; the one I now tigure : 12 x 11'5 X 

 5^ respectively. 



On removing the shell the visceral sac is pale-coloured, 

 sparsely and tinely spotted with black on the line of the 

 rectum. The loot is short and very narrow, indistinctly 

 divided, dark grey ; a distinct mucous gland overhung by a 

 blunt lobe, peripodial grooves, and a well-marked fringed 

 margin to the foot. There is a small but distinct and serrated 

 right shell-lobe, which would spread iurther in life ; the left 

 is a marginal band on the edge of the peristome. The genera- 

 tive organs were of great interest as they were unfolded. 

 The amatorial organ is of the usual form ; the penis retractor 

 muscle given off from a distinctly coiled caecum at the head 

 of the main penis-sheath. There is a long epijdiallus thence 

 to the junction of the vas delerens, with a long kale-sac 

 adjacent in wliich a spern)atophore had been developing. 

 Tlie sperniatheca is very long, gradually enlarging to the 

 distal tnd, and contained three spermatophores; these are of 

 tht 1} pe 1 have de.sciibeu in various species of Macroclilamys, 

 AuMeniii, &e. The flume had no large spines, but very 

 minute ones could be detected on the edges of it. This being 

 a single s})ecimen, which I have mounted in glycerine-jelly, 

 I did not like to destroy the sac of the spcrmatheca to get a 

 spermatophore out entire. In separating out the lengthened 

 genitalia of a close-wound shell such as this is, it is not easy 

 to do so without occasionally something breaking away. The 

 oviduct is peculiar, very straight up to the albumen-gland,
