nulata does not seem to resemble very closely tliat of i2, nigrocincta, 

 which has an apparently continuous broad yellowish-white band 

 down the middle dorsal line ; but in the specimen with distended 

 abdomen the anterior margins of the segments are also seen to be 

 coloured. The red-brown colour of the rest of the abdomen is 

 deeper on the ventral surface, the difference between the two 

 shades being sudden and sharp. A regular dark band along the 

 ventral abdominal surface seems common to many species of Bhax. 

 Simon describes the anal segment in B. annulata as black : in 

 a,, nigrocincta the prevailing colour of the segment is olive- 

 green ; it is covered with minute wart-like protuberances^with 

 white tips. 



Of other characters employed by Simon * for the classification 

 of these animals, I may mention that the ocular tubercle is oval 

 and transverse, the eyes are small, and the interval between them 

 is somewhat larger than the diameter of the eyes themselves.

This species differs in several important points from the fore- 

 going. "While the " head " and chelicerse are of the same colour, 

 the anterior edge of the former is marked by a pure white line, 

 hardly distinguishable from the white articulating membrane of 

 the mandibles, which shows very conspicuously at their bases. 

 The thoracic segments behind the "head" are pure yellowish 

 white, as are the legs, which latter have no trace of the black 

 rings characteristic of the Grundacul and the Yellore species 

 {B. annulata^ Simon, and 5. nigrocincta, n. sp.). The pedipalp 

 and the first pair of legs are, however, tipped with purplish 

 brown, and have a broad band of the same round the femur. 

 The colouring of the abdomen, again, is different from that of 

 any Bliax of which I have been able to find a description. The 

 dorsal surface is purplish brown without any median white band : 

 the colour gets lighter laterally till the ventral surface is quite 

 light, but spotted with darker patches so arranged as to appear 

 to be the remains of the dark band of colour so common on the 

 ventral surface in this genus. The anal segment is dark purplish 

 black round the anus itself, while its anterior margin is yellowish 

 white. The segment preceding the anal segment is entirely
