^^'ith the Hikkini altivagus in the British Museum is the 

 small specimen ret'erred to by Godwin-Austen (Land and 

 Freshwater Moll. India, 1882, p. 54). It has the oblique 

 lines on the back characteristic ot 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 ])ossibly the young of A. altivagus, but it is also 

 apparently TheobakPs modistus. lleynemann described a 

 similar form as the young of Schlaghdiceiti. If the young 

 of altivagus is striped, no doubt the young of a species so 

 closely allied as ISchlagintweiti 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 Schlagintioeitiy 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 rugai than in altivagus^ but pattern of reticulation the 

 same. These notes are from a specimen in the British 

 Museum marked " Coll. Schlagintweit, Simla to Sulsanpor 

 [Sultanpur, in G.-A. Moll. Ind.], Himalaya," and, apparently 

 in Dr. lleynemann's writing, '^Anadenus Schlngintweitiy 



Another specimen in tiie Britisii Museum from Kulu, 

 Himalaya {Schlagintweit), is also Scldagintweiti , but has the 

 sole more wrinkled and tlie median area narrower ; colour also 

 darker, but the white below mantle conspicuous. 



A. Scldagintweiti is exceedingly closely allied to altivagus, 

 but it may be a good species, it is easily distinguished by 

 its difi'erent coloration.
