Our two species differ in the shape of the cephalothorax. In 
pygmsea it is high, and is plainly widest in front, the cephalic 
part being strongly inclined, and projecting over the margin, 
so that the front eyes look downward and the clypeus and sides 
slant in. In aurata it is high and convex, but the widest part 
is behind the dorsal eyes, and the sides and clypeus are vertical. 
The front row of eyes is curved, the lateral eyes rather large. 
The second row is halfway in aurata, and nearer the third row 
in pygmsea. The third row is as wide as the cephalothorax. 
The sternum is nearly round. The labium is about as wide as 
long. The falces are vertical, or inclined backward, moderately 
stout, with one tooth on the lower border. 
The genus is found in the United States, Jamaica, and Porto 
Bico (signata B., illustris C. K.).
