MOLLUSCA OF INDIA. 2"3 



Austenki. 1 have also another species from Chamba, wliich I 

 consider to be scutella. 



On page 214, Vol. I., I described and figured, with considerable 

 doubt, a species from Uri, in the valley of the Jhelum, Kashmir 

 Territory, under the title cassida. Theobald, who sent it to me, 

 in one letter refers to it as that supposed cassida after seeing the 

 Simla specimens. 



I now feel satisfied that this Kashmir shell belongs to quite a 

 different group, of which MacroMamys Jle)aiiigi may be taken as 

 the type*. It comes nearest to Parvatella austeuiana and was 

 found in company with P. aUimr/a ; both of which I notice have 

 similar fine longitudinal striation. 



The species in spirit sent me by Mr. Annandale clear up all 

 doubt as to the generic position of cassida. There are some eight 

 specimens, pale grey or flesh-colour, and recall at once Hutton's 

 excellent description of the animal of cassida in the J. A. S. Bengal, 

 which I gave in full on p. 215, Vol. I. The shells of these Simla 

 specimens are fiat on the apex, and agree with the description 

 of monticola, Pfr., and here the confusion between monticola and 

 cassida is apparent ; the type-shell Pfeilfer described as monticola 

 really came from Simla, and not Mussooi-ie ; what Huttou and 

 Benson knew as monticola came from the last-named place. 



EuAUSTsyi.?; — as a section of Austenia — was indicated by 

 Cockerell, "Notes on Slugs," A. M. N. H. (6) vii. p. 98, 18!)1 

 (description Umited), " with an amatorial organ," type sciUdla : 

 Nautilus, xii. 1898, p. 10. No donbt based on description and 

 drawings, vide Moil. Ind. vol. i. 18S8, p. 232, pi. lii. figs. 1-1 e, 

 animal figs. 1-1 a ; from Murree in the Punjab, Outer Himalaya. 



Genus Euaustenia, Godwin-Austen, Paun. Brit. Ind., Moll. 

 (1908), p. 148. 



Original description : — " Shell differs from that of Austenia gigns 

 in being more heliciform, shelly and thin. The animal has large 

 leaf-like right and left shell-lobes, which in life nearly cover the 

 whole of the shell. In the genitalia the penis has a coiled cfBcnm 

 near the retractor muscle, and is thus similar to Macrochlamys." 



I have now dissected the animals of Euaustenia from four 

 widely separated localities— Naini Tal (Plate CXXIV. fig. 2), Simla 

 (Plate CXXIV. fig. 1), Chamba, and Murree, some 480 miles from 

 east to west : they pi'ove to be closely allied. The Simla species 

 was the first to be described by Captain Hutton in 1888 as 

 Vitrina cassida, long before Vitrina monticola, 1848, Pfr. monti- 

 cola, Bs. MS., is the Mussoorie and Landour shell, which is never 

 so fiat on the apex as cassida of Simla ; Pfeitter described it, 

 adopting the same name, in the P. Z. S. 1848. scutella, Bs., is 

 another form, the shell being still flatter above and still more 

 depressed ; stoliczlcana, Nevill (Plate CXXXI. tigs. 1, 1 a), is the 



* This shell has been made the type of a new genus, Parvatella, by W T 

 Blanford, Faun. Erit. Ind., Moll. (19Ub), p. 145.
