1872.] MAJOR GODWIN-AUSTEN ON NEW INDIAN SHELLS. 517 



Had. I found this species high up on Hengdan Peak, 7000 feet 

 on the Munipur boundary, among dead leaves in forest. I have 

 placed the last two species iu the subgenus Harpalus of Albers, after 

 comparison with H. grateloitpi, Pfr., from Luzon, and H. guineen- 

 sis, Jones. In Subulina the notch is hidden and rounded ; and to 

 this should, perhaps, belong Benson's genus Spiraxis (properly a 

 West-India form). I have an undescribed species from the Nicobar 

 Islands, found by Mr. Perd. Stoliczka, and provisionally named 

 Spiraxis ; but in the form of the aperture it is precisely similar to 

 H. munipurensis, as well as in its other characters. 



The genus Spiraxis of Benson differs iu the form of the aperture 

 from the above, and is a far more solid shell, if Sp. houghtoni be 

 taken as the type. In this last species we find an approach in some 

 of its characters to Achatina casiaca, Bs.* 



7. Hrlicarion (Hoplites?) croceus, sp. nov. (Plate XXX. 

 fig. 9, 9 a.) 



Shell very flat, rudimentary, oblong, thin, horny, transparent, pale 

 yellow-green, -with a longitudinal band of dark green, most intense 

 on the outer margin, extending from near the pale-coloured apex to 

 the edge of the peristome ; spire very short, apex flatly curved ; 

 peristome membranous, very thin, transparent ; within the single 

 body-whorl the colour is pale milky with some blue reflections. 



Diam. major 0'75, minor 0*35 inch. 



Animal is of a fine bright saffron-yellow colour ; when contracted it 

 has a richer gamboge tint ; mantle mottled with pale yellow ; a 

 narrow edging of yellow extends round that portion of the mantle 

 covering the shell ; another narrow band extends from the posterior 

 left side of the mantle towards the anterior left side, fining out and 

 terminating about § inch from the edge. Prom the posterior right 

 side a short line of yellow extends as far as the respiratory orifice ; 

 outside edge of foot very pale yellow, and almost white below ; ex- 

 tremity of foot truncate, with a gland as in H. gigas. Length of 

 animal 2| to 3 inches ; tentacles pale yellow, - -45. 



This very handsome species is very abundant during the height 

 of the rains in the valleys below Cflerra Poonjee ; and in the living 

 animal the small portion of shell not hidden by the mantle-lobes is 

 of a jet-black colour. 



8. Helicarion (Hoplites?) theobaldi, sp. nov. 



Animal of a pale yellowish dull grey, under surface of foot pale 

 light yellow.- The mantle-lobes completely cover the shell; a white 

 stripe extends from the posterior side forward along the edge of the 

 left lobe; and a like narrow white stripe from the hinder part of the 



* I may mention that the type of A. casiaca in Benson's collection is a shell 

 I obtained in the Niiga Hills, but never in the KMsi. The form in the latter 

 western locality is very distinct, much larger, more solid, and has not the well- 

 marked brown epidermis of A. casiaca. The KMsi species is much closer to 

 A. obtusa, W. Bit'., and requires figuring and describing ; this I hope to do on a 

 future occasion.
