NEW SPECIES OF SCOliriONS FROM INDIA. 263 



Tho ;;(Muis Slonochirus is now to tlio fauna of Hindustan. Ilitliorto 

 it lias been represented by a single speoies {S. sarasinorum)^ described by 

 Karsch, from Coylou (Berlin Eiit. Zoitschr., XXXVI, ]). 305, pi. xii, 

 fig. 80, 181)2). Tho last-named spooios is unknown to me, but judging 

 from Karsch's dosoripticn and figure, it may be distinguished from 

 S. politus by its shorter fingers and broader hand, the movable digit 

 being, according to the figure, less than twice the length of tho hand- 

 back, and the hand is wider than, or at least as wide as, the brachium. 

 Again, in the tail of S. sarasinorum tho length of tho 2nd sogmont is 

 much less than the width of the 4:th. Moreover, nothing is said in 

 tlio description given by Karsch of tho granulation of the carajjace 

 and dorsal plates of tho abdomen which is so noticeable in S. poliiuts.
