In the most recent publication '' Tiie Fauna of British 

 India/' Vol. II, Molkisca, p. 211, 1914, the range of H.huttoni 

 is to say the least very remarlcable, it is apparently copied from 

 Nevill's " Hand List " of 1878, then 36 years old and thus with no 

 further advance in our knowledge. These habitats are India 

 (Simla and Landour) ; Darjiling; Kashmir; Naga Hills; Dafla 

 Hills; Shevroy Hills; Burma, Upper Salween Valley; Puppa 

 Hills near Ava ; China ; and Ponsee, Yunnan. With the exception 

 of Kashmir, I fortunately have examples of most of these.

lobes^ and thus it resembles the animal of Rahula. The extremity 

 of the foot has a small lobe above the small slit of the mucous 

 gland (text-fig. i, B), the peripodial margin is very broad with two 

 grooves above well defined. The genitalia (text-fig. i, C) were 

 well got out, the penis (/>) consists of a long sheath, the retractor 

 muscle strong and short at the end, a long epiphallus [ep] follows 

 and where the vas deferens joins there is a well-developed flagellum. 

 The spermatheca {sp) rises about half way up the free oviduct and 

 has a globose termination. This does not agree with Stoliczka's 

 figure, plate ii, fig. 7, J.A.S.B. 1873, described on p. 21, and
