Major diam. 16| mm. 



Hal}. Banks of Radha Pokri (tank), near Narrainpur, Darrang 

 District, Assam {Godwin- Austen}. 



Animal rich ochre, sparsely dappled with grey-black on the 

 mantle and tail. Length when extended 3 inches, mantle 1'3.

 The mantle quite conceals the shell and covers the animal as far 

 the head. 



[Girasia? rubra, Godwin-Austen, transferred to genus Crypto- 

 girasia, p. 204.] 



302. Girasia crocea, Godwin-Austen, Helicarion (Hoplites), P. Z. S. 



1872, p. 517, pi. 30, figs. 9, 9 a (animal crawling and shell) ; Nevill 

 (Parmarion), Hand-l. i, 1878, p. 13 ; Godwin- Austen, Mol. 2nd. 

 i, 1888, p. 223, pi. 60, fig. 2 (animal), pi. 62, fig. 6 (radula). 



Shell very thin, flat, rudimentary, horny translucent, with a 

 broad band of dark green from the apex to the edge of the mem- 

 brauaceous peristome; apex pointed and projecting, without 

 any distinct coil ; peristome convex throughout, except where it 

 approaches the apex, when it becomes concave. 



Major diam. 18, min. 8 mm. 



Hob. Valleys below Cherra Punji, Khasi Hills. Found creeping 

 on high grass near Teria Ghat (Godwin- Austen). 



Animal a fine bright saffron-yellow colour, mantle mottled with 

 pale yellow; outside edge of foot very pale yellow and almost 

 white below ; extremity of foot truncate, with a gland as in 

 Austenia gigas. Length of animal 2J to 3 inches. 



Odontophore quite peculiar. The middle tooth has three sub- 

 equal cusps, all at the extremity, the next 9 on each side have a 

 small outer cusp ; the outer teeth are throughout evenly bicuspid, 

 decreasing in size to the outermost laterals. They are thus 

 arranged : 100 . 9 . 1 . 9 . 100 (109 . 1 . 109). This is quite 

 different from any Girasia, and the only similar arrangement is 

 found in Durgella khasiaca.

p. 225, pi. 59, figs. 1-1 c (animal). 



" Animal with the right and left mantle-lobes united ; the 

 mantle appears to be slightly speckled. The shell is deeply sunk
