250 ANADENUS. 



A. SCHLAGINTWEITI, Heyneinaim. PI. 59, fig. 61. 



Apparently externally very similar to A. altivagus but smaller, 

 but differs slightly in dentition and shell. Color of animal ash- 

 gray or blackish. Length (in spirits), 45 to 60 mill. 



Shell 11 mill, long, 7'5 mill, broad ; massive, thick, flat. 



Himalayas, to an alt. of 13,420 feet ; probably living on fungi. 



" In the young animal the back part of the mantle has a black 

 spot which runs in a point in front and encloses a small space, 

 which is brighter than the rest of the mantle ; the sides of the 

 mantle are black-spotted, and down the sides of the body runs a 

 black stripe, which towards the back is sharply marked out, but 

 towards the sole is shaded off; the top of the back is again some- 

 what darker.

Animal large ; mantle apparently finely papillate in life ; foot 

 above very coarsely wrinkled, rounded at extremity ; a very 

 narrow pedal margin ; respiratory orifice behind the middle of 

 the right margin of the mantle ; the eye-tentacles appear to be 

 very large at the base ; mantle, viewed from above, rather circu- 

 lar in form ; sole with wide central area.
