7o Records of the Indian Museum. [Vol. VIII, 



laterally with strong marginal ridges ; posterior margin composed 

 of two straight halves meeting in an angle of about 120°. Ventral 

 surface paler than dorsal, similarly punctured, but without 

 grooves ; sternocoxal plate armed with five strong teeth (some- 

 times four or six on one side onh^). Sternum of anal segment 

 narrower behind than in front, posterior margin more or less 

 concave. Pseudopleural processes at least as long as sternum of 

 anal segment, sometimes very slender behind, armed with 1-2 distal, 

 1-2 external, and 1-4 dorsal spinules. Tooth on inner side of femur 

 of poison-jaws strongly developed. Legs distally of a more bluish 

 tinge than the body. First pair of legs armed with i distal 

 spine on the patella, i on the tibia, 2 on the proximal tarsus, 

 and 2 at the base of the claw ; second with 2 spines on the 

 proximal tarsus and claw, with or without i on the tibia; third 

 to twentieth with 2 at the base of the claw, i, or usually in 

 many of the anterior segments 2, at the end of the proximal 

 tarsus ; anal legs with 2 at the base of the claw only ; femur 

 of anal legs with a strong dorsal tooth on the inner side at the end 

 (" eckdorn ") with 1-3 smaller teeth behind it, beneath on the 

 outer side with 3, on the inner with 2, 2-3, 3 teeth often irregularly 

 arranged. 



This species is allied to those grouped under the number 5 

 in Kraepelin's table [Revision der Scolopendriden, p. 99, in Mitt. 

 Naturhist. Mus. Hamburg, XX, 1902 (1903)]. It differs from all of 

 them, however, in combining the presence of external spinules on 

 the pseudopleural processes with the absence of longitudinal grooves 

 on the sterna. 



O. insularis, Haase. 



Kobo, 400 ft., 8-xii-ii. 



Rotung, 1,300-1,400 ft., 3T-xii-ii and i-i-12. 



This species is recorded from the Seychelles, Ceylon, the 

 Philippines, and the E. Himalayas. 



Several specimens have recently been added to the Museum 

 collection. In addition to the Abor records above noted, the 

 following localities may be given : — 



Ceylon: Kandy and Peradeniya, 1,500-2,000 ft. 



B. Himalayas: Darjiling District — Ghumti, ca. 1,800 ft. 



Assam : Mangaldai District — -Assam-Bhutan Frontier. 

 Dikrang Valley. 



Malay Peninsula : Penang. 



Individuals differ greatly one from another in man}- respects. 

 Kraepelin has pointed out that the Himalayan form differs 

 from the Ceylon one in having only two instead of two and half 

 segments of the antenna smooth and hairless. This is confirmed 

 by the specimens I have seen, the Penang specimen agreeing with 

 the Himalayan ones in this respect, but as two of the Himalayan 

 ones have two and half segments bare on one antenna I am in- 

 clined to think he was right in not giving the two forms separate
