Pectines furnished with 13 — 15 teeth. 



Length about 30 mm. 



Locality.— Bhopal, Central India {Surgn.-Lieut.-Col. Dane). 



Eecoo-nisable by the following characters : — (1) the fifth segment of 

 the tail is short and stout, its width and height being nearly half its 

 length ; in the other Indian species the width and height are only 

 about one-quarter of the length ; (2) the movable digit is only a little 

 longer than the hand-back instead of about twice the length ; (3) the 

 superior terminal keel of the third segment terminates in a long 

 upstanding spine.

$ . Closely allied to the cosmopolitan I. maculatusj but differing in 

 the following particulars :-— The black bands on each side of the pale 

 anteocular patch on the carapace converge anteriorly and meet in 

 the middle line on the anterior border of the carapace. The hands 

 and digits of the chelse may be described as fuscous, but mottled 

 with yellow, whereas in I. maculatus the hands are yellow, spotted 

 black externally, and the digits are of a uniform brownish- red tint. 

 Correlated with this distinction in colour is an important character 

 connected with the pectines, these organs being armed with 15-16 teeth, 

 and having the base of the shaft produced into a semicircular rounded 

 prominence much resembling that which is seen in the allied South 

 American genus Tityus. So far as I am aware this feature is found 

 in no other species of the genus Isometfus. The male of this form 

 is unfortunately not yet known,

Coloured like P.fulvipes, with reddish-yellow legs and vesicle, but 

 allied to P. bengalensis in the form and sculpturing of the hand of the 

 chelce and in most other characters appertaining to the trunk and
