364 REV. O. V. CAMBRIDGE ON NEW SPIDERS. [JuUC 5, 



with brown ; the caput is strongly marked, mottled, and suffused 

 with deep yellow-brown ; the thorax has a fine submarginal line, 

 as well as some converging lines and other markings, of the same hue. 

 The height of the clypeus is equal to half that of the facial space. 

 On the caput are a few shortish bristly hairs. 



The eyes of the hind-central pair are much wider apart than 

 each is from the lateral eye on its side ; the same proportionate 

 separation is observable, though not to the same degree, in the 

 eyes of the anterior row. The fore-centrals are the smallest of 

 the eight. 



The leffs are of a pale dull yellowish hue, with a few obscure blotches 

 of white, and more or less marked and spotted with blackish brown. 



The falces are similar in colour to the cephalothorax, thinly 

 mottled and marked with dark yellow-brown. 



The waxillce and labium are pale whitish yellow-brown. 



The sternum is similar to the falces in colour ; its central portion 

 deep yellow-brown. 



The abdomen is thinly clothed with hairs and a few short 

 bristles ; its colour is a dull whitish yellow tinged with brownish, 

 somewhat speckled and marked with yellow-brown and deep 

 black-brown ; some of the deeper markings are lineate and oblique, 

 others, towards the hinder part, are transverse ; a small elevation 

 halfway between the fore extremity and the beginning of the hinder 

 slope is marked with a somewhat curved, transverse, geminated spot, 

 forming probably a characteristic central abdominal marking. The 

 underside has a broad longitudinal central baud suffused with sooty 

 brown, deepest along its margins. 



An example of this curiously formed Spider was received from 

 Mr. Mausel Weale, by whom it was found in Caffraria. It is 

 evidently allied to Monastes, Luc. ; but a consideration of its 

 abnormally formed caput and some other characters have induced 

 me to found a new genus upon it.
