 CoxEe pale. 



Habitat. Brazil. Smith collection. 



PARADAMCETAS P., 1885. 



Cephalothorax moderately high, convex, a little dilated at 

 dorsal eyes ; cephalic part a little inclined. Quadrangle of eyes 

 about one-fifth wider than long, a little wider behind than in 

 front, occupying one-half of the cephalothorax. Anterior eyes 

 in a straight row, middle twice as large as lateral, middle 

 touching, lateral subtouching. Eyes of second row very small, 

 nearer the lateral than the dorsal eyes. Dorsal eyes as large as 

 the lateral, in a row as wide as the cephalothorax at that place. 

 Lip a little longer than wide.

In the female the cephalothorax has a small, semi-circular 

 region behind the dorsal eyes which falls but little below the 

 plane of the cephalic part, and from this there is c^uite an 

 abrupt slope to the lower border. In the male the distinction 

 between the two inclinations is not so clearly defined, the effect 

 being rather a gradual slope from the dorsal eyes. Falces ( $ ) 

 as wide as first row of eyes, three times as long as face, hori-
