702 MESSRS. G, \V. AND E. G. PECKHAM ON [NoV. 21 , 



2 . Length 5. Length of cephalothorax 2*1. Width of 

 cephalothorax 1*8. 



Legs, c? 2 , 1,4, 3, 2; first pair much the stoutest and longest, 

 especially in the male. 



The falces of the male are long, longer in some specimens than 

 in others, and horizontal. Their inner edges are parallel for about 

 one-half their length and then diverge ; at this point is a tooth, 

 which points forward and crosses the one on the opposite falx. 

 The fang is long and slender and is slightly curved at the 

 extremity. Those of the female are vertical, parallel, and mode- 

 rately long and stout. The sternum is rather long, and is widest 

 in the middle. The maxillas are nearly twice as long as the 

 labium. The labium is longer than wide. 



The colour of the male is bronze-brown. A snow-white band 

 on each side extends throughout the whole length of the cephalo- 

 thorax and abdomen, the cephalothorax having a dark line around 

 the lower margin. The eyes of the first row are surrounded by 

 white hairs. The falces are bronze, slightly rugose above, with a 

 band of white hairs along the outer side of each. The fangs are 

 black. The first legs are bronze above and blackish below, and 

 are thinly covered with Avhite hairs. The other legs are light 

 yellowish brown. 



The female has the cephalothorax and abdomen thickly coA-ered 

 with a mixture of white, red, and yellow hairs. On the anterior 

 part of the abdomen are two pairs of black dots, and across the 

 posterior part, halfway between the middle point and the spinnerets, 

 is a transverse black band. The legs are yellowish brown, the first 

 pair being the darkest and having some short white hairs.

S . Length 3. Length of cephalothorax 1*5 ; width of cephalo- 

 thorax 1. 



2 . Length 3*7. Length of cephalothorax 1*7; width of cephalo- 

 thorax 1*3. 



Legs, c? 1) 4, 3, 2, $ 3, 4, 1, 2 ; almost equally stout in both 

 sexes. 



The cephalothorax is high, the highest point being at the dorsal 

 eyes ; it is widest in front. The cephalic part is strongly 

 inclined for\A-ard and projects over the loMer margin, the sides and 

 clypeus slanting inward. The thoracic part falls a little in the 

 anterior two-thirds and then drops abruptly behind ; the lateral 

 slopes of this part are slightly rounded out. Tne quadrangle of 

 the eyes is one-fourth wider than long, is plainly wider in front 

 than behind, aud occupies a little less than one-half of the cephalo- 

 thorax. The four anterior eyes are close together and form a 

 curved row ; they are not very unequal in size, the lateral being 

 about two-thirds as large as the middle eyes. The front face of 

 the cephalothorax is so inclined that the eyes of this row look 

 downward. The second row is plainly nearer the third than the 

 first row, and the eyes are placed on the sides of the cephalothorax.
