Plate XVI., Figs. 6—6d. 



S . Length varying from 3.2 to 4.5. Length of cephalo- 

 thorax of the larger variety, 2 ; width of cepbalo- 

 thorax, 1.7. 



Legs, 1423 ; first pair stoutest and much the longest. 



9 . Length, 4.6. Length of cephalothorax, 2 ; width of 

 cephalothorax, 1.7. 



Legs, 4123. 



The anterior end of the abdomen overlaps and lies close 

 upon the posterior end of the cephalothorax. The falces of the 

 female are vertical, rather long, and moderately stout. In the 

 male they are obliquely directed forward and are long and 

 strong, with very long, curved fangs. At the proximal end is 

 the pointed, vertical apophysis, common to the males of this 

 genus, and on the under side of each falx is a curved apophysis, 

 or horn, visible only from below. The palpi of the male are 

 slender and greatly elongated. 



In the male the cephalothorax, falces, palpi and first legs 

 are bronze, with a thin covering of white hairs. There are two 

 black spots on the eye region and the eyes are surrounded by 

 black rings. The abdomen is also bronze, with a line of chev- 

 rons in brown down the middle of the dorsum. The lower 

 sides are black, and three black bands come up on each side 

 on to the dorsum. There is a snow-white band of hairs 

 around the anterior end, and a pair of white spots near the 

 posterior end. The second, third and fourth pairs of legs are 

 brown. 



The female has the cephalothorax bronze with the black 

 spots on the cephalic part, and around the e5^es, as in the male ; 

 but the covering hairs are yellow rather than white. The legs, 

 palpi and falces are brown. The integument of the ab- 

 domen is pale brown with a darker herring-bone stripe down 

 the middle, some dark bands coming up over the sides, and 

 four distinct, black spots on the dorsum. 



We have numerous individuals from jNIandeville, Mon- 

 eague, and Kingston, Jamaica.
