ducts. The ovary is exogenous. The ova are large and heavily 

 charged with yolk and measure from 1*5 to 2 mm. in their longest 

 diameter. The uterine embryos are of all ages and do not possess 

 a trophic vesicle. 



In the male the testes are tubular ; the vesiculae seminales 

 are of very large size and occupy the greater part of the body- 

 cavity between the tenth and thirteenth pairs of legs. The un- 

 paired part of the vas deferens is of enormous length, reaching 

 in one specimen as far as the fifth leg, in another to the inter- 

 space between the seventh and eighth pairs. The spermatophore 

 is very long and is provided with a horny cap in front. The 

 accessory glands of the male consist of convoluted tubes which 

 open separately in front of the anus. Of crural glands there is a 

 single pair in each of the legs preceding the genital opening. 



The skin pigment is slowly extracted by alcohol. Living 

 specimens were dorsally of a deep raw umber brown colour with 

 the ends of the antennae and the tips of some of the primary 

 tubercles pale buff. Ventrally the animal was entirely pale. 



The specimens were all found in the vicinity of Rotung, on 

 the banks of the Dihang river, living under stones at altitudes 

 varying from 1200 — ^2500 feet.
