chelicerae. The female, however, differs from that of 0. marmorea 

 in having the vulva neither redder nor smoother than the surround- 

 ing blackish matt integuments, and with a conspicuous longitudinal 

 oval groove in front. The male differs in the armature of the cheli- 

 cerae (see fig, jc). There are two teetli on the ventral margin of the 

 fang-groove, placed close together one behind the other at the base 

 of the fang, the anterior being much larger than the posterior ; and 

 there is a large obtusely conical tubercle much nearer the base. 

 The dorsal margin bears two widely separated teeth with a more 

 or less obsolete denticle in. front of the proximal one, much as in 

 the male of 0. marmorea.

The following is a list of the principal descriptions of species 

 recorded from the Oriental Region and of some of those found on its 

 borders. Several of them have, however, already been relegated 

 to the synonymy of common and widely distributed species (see 

 synonymy of the species in the collections under consideration) 

 and it is possible that others will have to follow them. On the 

 other hand several species originally described as Meta or Tetrag- 

 natha have had to be transferred to Leucauge, and it is possible 

 that others may have to follow these also, descriptions of a num- 

 ber of which from places borderhig on the Oriental Region have 

 been given bv Thorell in his •' Ragni di Selebes " (1877), " Ragni 

 di Amboina '"' (1878) and " Ragni Aiistro-Malesi" (1881).
