Remarks.—Execept for a slight twisting of the dactyls P. capillatus in general 
appearance is very similar to P. setosus, but neither is the large hand propor- 
tionally so long nor are its more numerous spines nearly so strong or so distinctly 
arranged in longitudinal rows. In specimens of the same size the spines on the 
large hand of P. capillatus are only half the size of those of P. setosus. The 
large hand of P. setosus is about twice as long as wide, with more depressed 
fingers than those of P. capillatus. The large hand of P. capillatus is usually one 
and a-half times as long as wide, occasionally one and three-fourths times as long 
as wide. I have seen one specimen only in which the hand, was longer, about twice 
as long as wide; but the characteristic armature of the large hand precludes any 
confusion as to its identity. Furthermore, the triangular outer face of the small 
hand of P. setosus is more rounded and not so prominently and broadly triangular 
as that of P. capillatus, being about four times as long as wide. In P. capillatus 
the triangular outer face of the small hand is about three times as long as wide.

Characters.—Anterior portion of carapace wider than long, squarish or squat 
looking; median projection of front triangular, acute. Eye-stalks short and stout. 
Acicle typically exceeds eye-stalk but frequently falls short of it. Carpus of large 
cheliped not deeper than wide, inner and lower faces not meeting at a distinct 
angle. Small hand wider than deep, outer face oblique, triangular, more or less 
swollen. Carapace and ambulatory legs more or less hairy; dactyls moderately 
stout, about as long as propodi. 
Dimensions.—Type: length 31.8 mm. The carapace of the specimens taken 
in the Bay averaged between 6 to 9 mm. in length, the longest being about 
12 mm, long.
