long ; sole lat. 23§ millim. ; median area, lat. 10^ millim., 
thus broader than either lateral area ; lateral areas granulose. 
Anadenus modestus^ Theob. 
With the Sikkim altivagus in the British Museum is the 
small specimen referred to by Godwin- Austen (Land and 
Freshwater Moll. India, 1882, p. 54). It has the oblique 
lines on the back characteristic of section Altivagi , and also 
the flattened tail. It is 19^ millim. long; mantle 8 millim. 
long, respiratory orifice slightly posterior, i. e . 5 millim. from 
anterior border. Sole, lat. 5^ millim., median zone broader 
than either lateral. Colour dull greyish ochreous, with lateral 
black marbling on mantle (representing broken-up lateral 
bands) and black lateral bands, irregular in outline, on body. 
This is very possibly the young of A. altivagus , but it is also 
apparently Theobald'’ s modestus. Ileynemann described a 
similar form as the young of Schlagintweiti. If the young 
of altivagus is striped, no doubt the young of a species so 
closely allied as Schlagintweiti would be similar, and the 
immature slugs might be very hard to distinguish specifically. 
There can be no doubt, supposing these striped slugs are 
juveniles, that Theobald’s modestus is the young of altivagus 
or Schlagintweiti. 
Anadenus Schlagintweiti , Heyn. 
Colour grey, slightly olivaceous, becoming white beneath 
mantle posteriorly. Neck and head dark above. Sole 
narrower than in altivagus , median area approximately of 
equal width to either lateral area. Mantle 24 millim. long, 
respiratory orifice slightly anterior to middle. Back with 
flatter rugae than in altivagus , but pattern of reticulation the 
same. These notes are from a specimen in the British 
Museum marked u Coll. Schlagintweit, Simla to Sulsanpor 
[Sultanpur, in G.-A. Moll. Ind.], Himalaya,” and, apparently 
in Dr. Heynemann’s writing, u Anadenus Schlagintweiti .” 
Another specimen in the British Museum from Kulu, 
Himalaya [Schlagintweit) , is also Schlagintweiti , but has the 
sole more wrinkled and the median area narrower ; colour also 
darker, but the white below mantle conspicuous. 
A. Schlagintweiti is exceedingly closely allied to altivagus , 
but it may be a good species. It is easily distinguished by 
its different coloration.
