Dcscrijjtions of several neio Species of Thelyphonus : by 

 Arthur G. Butler, F.L.S., F.Z.S., &c. 



PLATE V. 



Mr. Whiteley having lent me some Theh/plioni from 

 Birmah, I have carefully reexamined the specimens in the 

 Collection of the British Museum, the result of which has 

 been to convince me that the species of this genus are less 

 subject to variation than I supposed them to be when I 

 wrote my Monograph. The following species therefore 

 remain to be described as new : — 



1. Thelyphonus Psittacinus, n. sp., fig. 2. 



Allied to T. Rufimanus (fig. 1), but at once distinguish- 

 able from the greater size and less dentated character of 

 the clieliceres. 



Same colours as in T. Rnfimanus, excepting that the 

 basal joint of cheliceres and the abdomen are blacker 

 below. 



Cephalothorax with the sides slightly more parallel, 

 abdomen with stigmatiform depressions rather better 

 marked, legs slightly more robust, otherwise as in T. Rufi- 

 manus ; cheliceres more minutely and sparsely tuberculose, 

 first joint broader in front, terminal spines longer, second 

 joint broader, the inner tooth more widely separated from 

 the others, third joint longer, the spinous inner edge 

 rounded off, fourth joint altogether larger, its process and 

 inner edge not dentated ; chela3 altogether larger and more 

 than twice as broad, the inner edge below the fixed finger 

 projecting towards the process of fourth joint, fixed finger 

 much shorter, moveable finger broader, longer, and more 

 curved at the end. 



Length of cephalothorax and abdomen, 1 inch, 11 lines. 



Silhet (Stains forth). 4 specimens. B.M. 



We have 11 examples of the allied T. Rufimanus in 

 various stages of growth : T. Psittacinus is in Mr. W. 

 Wilson Saunders's Collection from K India.
