Cephalothorax moderately high, nearly plane, a very little dilated behind 

 dorsal eyes, with sides nearly vertical in front and rounded behind; 

 cephalic part very slightly inclined; thoracic pai"t with the first half

 than long, wider behind than in front. First row of eyes straight; 

 middle eyes sub-touching; lateral one-half as large as middle eyes, and 

 a Uttle separated from them; eyes of second row a little nearer lateral 

 than dorsal eyes; dorsal a little smaller than lateral eyes, further 

 from each other than from lateral border, forming a row which is 

 narrower than the cephalothorax at that place. Clypeus a Httle more 

 than one-fourth as high as middle eyes. Falces compressed, parallel, 

 extending to inner edges of lateral eyes, ( $, ) three times as long as 

 face, horizontal, (?) as long as face, vertical; fang ( ^ ) as long as 

 falx, ( 9 ) short. Maxillee long, enlarged at extremity, ( $ ) with pro-

 excavated. Labium two-thirds as long as maxillae, nearly twice as 

 long as wide, contracted and rounded at tip. Sternum oval, one-half 

 longer than wide, scarcely i^rojecting between anterior coxae. Ante-
