is curved downward ; the middle eyes of this row are a little 

 less than twice as large as the lateral, and the second row is 

 nearer tlie third than the first row. 



The legs are weak, and of a very pale brown color. The 

 first legs are the stoutest, and, in some specimens, are much 

 darker colored than the others. 



We have numerous individuals of both sexes and of A'ari- 

 ous ages. 



M. Simon sends us this species, marked simply " Brazil." 

 We have it also in the Smith collection from Chapoda. 



The beetle-like .shell which characterizes this species is not 

 acquired until the spider is two-thirds grown.

The cephalothorax is low and flat, and is about one-third 

 longer than wide. It is widest opposite the dorsal eyes. The 

 cephalic and thoracic parts are on the same plane. The cephalic 

 part occupies two-thirds of the cephalothorax. The thoracic 

 part is narrowed on the sides and above to a Vjlunt point, and 

 does not fall until near the posterior border. 



The quadrangle of the eyes is about as long as wide, and 

 is wider behind than in front. The anterior eyes are close 

 together in a curved row. The middle are twice as large as 

 the lateral. The second row is nearer the first than the third. 

 The third row is as wide as the cephalothorax at that place. 

 The eyes of this row are further from each other than from the 

 lateral borders. 



This genus is characterized by the very long cephalic part, 

 and the low, flat cephalothorax. The type is C. cheliferoides
