90 COLLINGE : NON-OPERCULATE LAND AND FRESHWATER MOLLUSCS. 



Atopos rugosus, n. sp. 



PI. V, figs. 46-48. 



Colour of notum, dark green with yellowish-brown spots, granulated, 

 the extreme anterior portion of the notum is almost white, while pos- 

 teriorly the body is sharply pointed ; underside (perinotum ?) yellowish ; 

 foot-sole dirty yellow ; keel fairly well developed, yellowish brown in 

 colour. Length of notum (in alcohol) 43*5, breadth 7, height 8 millim. 

 Breadth of foot-sole 4 millim. Female generative orifice 8'5 millim. 

 from the male generative orifice. 



Hah. — Hills near Biserat, State of Jalor. 



Atopos punctata, n. sp. 



PI. v, figs. 49-52. 



Colour of notum, yellow spotted with dark blue or black, granulated ; 

 head and tentacles yellowish ; underside (perinotum ?) yellow ; foot- 

 sole yellow with closely set transverse wrinkles ; keel fairly prominent. 

 Length of notum (in alcohol) 35, breadth 4, height 4 millim. Breadth 

 of foot-sole 2 millim. Female generative orifice 7 (?) millim.* from 

 the male generative orifice. 



Hah. — Hills near Biserat, State of Jalor. 



A figure of a small piece of the notum much enlarged (PI. vi, fig. 5 2), 

 shows that the wart-like bodies vary greatly in size, as do also the blackish 

 spots.

Atopos dnihelJi, Simr. : Zeit. f. wiss. Zool., 1893, Bd. Hi, p. 600. 

 The specimen collected agrees practically in all details with the 

 description given by Simroth. The dimensions are as follows : Length 

 of notum (in alcohol) 61 '5, breadth 11, height 11 "5 millim. Breadth 

 of foot-sole 7 millim. Female generative orifice 13 millim. from the 

 male generative orifice.

Atopos laidlawi, n. sp. 



PI. V, figs. 53-55. 



Colour of the notum, dorsally yellowish-brown with small, dark brown 

 dots, finely granulated, laterally an irregular, broad, dark brown band, 

 below which the notum is drab colour, at the extreme anterior and 

 posterior ends the notum is almost white ; head dirty white ; tentacles 



* Ii is exceedingly difficult in small species like these, which have become hardened and some- 

 what brittle by immersion in alcohol, to be certain of the actual orifice.
