CHAPODA, GExV. NOV. 



The cephalothorax is rather high. From its highest point 

 at the dorsal eyes it slants plainly in hoth directions, more 

 markedly behind than in front ; after the fir.st half the thoracic 

 slope is still more abrupt. There is a large post-ocular de- 

 pression. In the female the sides of the cephalic part are ver- 

 tical, but in the male, where the cephalothorax is higher, they 

 widen from above below, botli in cephalic and thoracic parts. 

 The narrowest point is at the front end, and the widest behind 

 the dorsal eyes. The quadrangle of the eyes is a little wider 

 in front than behind, is one-fifth wider than long, and occupies 

 about two-fifths of the cephalothorax. The anterior eyes are 

 large and form a plainly curved row ; the middle eyes are close 

 together and are plainly less than twice as large as the lateral, 

 which are a little separated from them. The second row is 

 half-way between the first and the third. The third row is not 

 quite so wide as the cephalothorax at that place. 



In general appearance, and in the enamelled surface of the 

 integument, this genus resembles certain species of Amycus. 

 The cephalothorax, however, is not so high, and the lateral 

 eyes of the first row are relatively larger. It is still closer to 

 the following genus, Helorus, but the spiders are smaller, with 

 the cephalothorax lower and the quadrangle of the eyes nar- 

 rower in proportion to its length.
