80 ISCIINUBIDiE. 



Loc. Burma : Akyab ; Myanyouug, Moulmein ; Kawkareik, 

 Thagata-juva, aud Mount Mooleyit, in Tenasseriui ; Tavoy and 

 Reef Island (Feci <j- Oates); Great Coeos Island, Andainans (Oates); 

 Nicobar Islands, thence over the whole of the Iudo-Malayan 

 and Austro-Malayan area. 



Adults of this species vary much in size, some males with fully- 

 developed sexual features being only about 30 mm., the carapace 

 measuring 5, and the adult females may reach 45 mm. or more. 



Subspecies suspectus, Thorett: Horniurus australasise, Fabr., var. y. 

 suspectus, Thorell, Ann. Mies. Genova, xxvi, pp. 420 & 422, 1888. 



Differs from the Burmese representative of the typical form in 

 having the upper side of the trunk and the tail, with exception of 

 the yellowish-red vesicle, a deep greenish black, the chelae being 

 of much the same colour, and the legs, although ferruginous towards 

 the extremities, are piceous and not paler than the upper side of 

 the trunk. Total length of adult S 42 mm. 



Loc. Lower Burma: Prome (Feci) and the Pegu Hills (Bingham). 



The granulation of the carapace and terga, which Thorell relied 

 upon as a basis for this form, is not more strongly developed than 

 iu many males of the typical form. 



66. Horniurus nigripes, Pocock, Jour. Bom. N. II. Soc. xi, p. 117, 

 1897; Kraepelin, Tierr., Scorp. etc. p. 155, 1899. 



Colour a shining pitchy brown, only the vesicle yellow ; legs as 

 dark as the body, with the exception of the tarsi which are yellow. 

 Carapace smooth and punctured as in //. australasice, but with the 

 frontal border more deeply excavated and the frontal lobes more 

 square. Terga much less conspicuously punctulate than in 

 //. australasice ; sterna also scarcely noticeably punctulate. Tail of 

 about the same strength and with the same armature of dentiform 

 tubercles as in //. australasice, but the segments are very noticeably 

 shorter as compared to their length, and with the exception of the 

 above-mentioned sharp tubercles are entirely without granules. 

 Chelce as large as in 77. australasice ; humerus with granules and 

 tubercles weaker; the upper surface of brachiuin smooth and 

 punctured, crests of its posterior surface almost or quite smooth, 

 the edge of the anterior basal prominence not produced into a 

 crest bearing spiuiform tubercles; hand punctulate and granulate 

 as in If. australasice, but with its posterior external angle pro- 

 jecting much more strongly, and the area opposed to the brachiuin 

 prolonged internally so that when closed it overlaps the basal 

 prominence of the brachiuin ; in 11. australasice it falls short of the 

 prominence, the teeth of which abut against the inner edge of the 

 hand. Pectinal teeth 6 in $ . 



Measurements In mm. — Total length l)o, of tail 14, carapace 6*3, 

 underhand 6, movable finger 4*2, width of hand 3*8. 



Loc India: Paneh Mahals in Guzerat (Wallinger) ; Satna in 

 Central Provinces (Dane).
