Genus Cyphophthalmus (Joseph) . 

 Cyphophthalmus cimiciformis, sp. n. PI. XIII. fig. 3. 



Length 1| line, breadth nearly 1 line. 



Nearly the whole of this Arachnid is of a dull amber-colour, 

 the legs and falces being rather paler than the body, the fore 

 part of which (the cephalothorax) is the darkest, the colour of 

 the palpi being palish yellow ; the entire surface (including 

 the legs and falces) is completely covered with shallow punc- 

 tures, giving it a somewhat rugose appearance, with a shining- 

 look in different lights ; the under surface, as well as the legs 

 and palpi, is furnished with fine hairs ; but the upper surface 

 has few or none (perhaps rubbed off). 



The form of the cephalothorax and abdomen is oval, the 

 former, however, being of a somewhat subtriangular shape ; 

 they are only distinguishable from each other by a transverse 

 suture ; the abdomen consists, on the upperside (which with the 

 cephalothorax is considerably convex), of eight segments, of 

 which the last is divided into two roundish caudal prolongations. 

 The segmental plates of the underside, which is much more 

 flattened than the upper, are similar in number ; the posterior 

 one contains the anal orifice, which is of a transverse oval 

 form and a little prominent ; the inferior segmental plates are 

 quite separate from the superior (see fig. 3, c), the latter form- 

 ing a strong projecting lateral marginal ridge : in front of and 

 adjoining the foremost inferior segment is a small, subtri- 

 angular, dark reddish-brown corneous plate, the fore side of 

 which is free ; this plate is no doubt the covering of the 

 genital aperture, which, as far as concerns the external appear- 

 ance, is probably similar in both sexes. Immediately in front 

 of this is a small sternal point, at which the basal joints of 

 the legs meet ; directly in front of this, between the basal 

 joints of the first pair of legs, are two pairs of very small, but 

 prominent, white maxillary organs ; the foremost pair of 

 these is the largest ; the hinder extremities of the basal joints 

 of the second pair of legs are a little prominent, and appear to 

 subserve the part of a labium, and to form the hinder boundary 

 of the mouth. These maxillary organs seemed to be inde- 

 pendent of the ordinary maxilla?, i. e. the basal joints of the 

 palpi ; but the mouth-parts are so crowded together behind 

 the basal joints of the first pair of legs, that, without very 

 careful and skilful anatomy, their structure and position can 

 scarcely be ascertained. The spiracles (two in number) are
