PYLOCHELES PARTITUS, new species. 



The frontal line of the carapace is made up of a .short, straight line, 

 in the middle ending in a short, sharp tooth. This is followed l)y an 

 angular sinus, with a slightly carinate margin. This sinus ends at the 

 outer line of the eye. Its teriuinus is marked by a small spine. 

 Beyond this point the margin is straight for the width of the antenna, 

 and runs diagonally back to where it rounds into the side. The eye- 

 stalks are stout, straight to the middle, where they expand to the 

 moderately dilated cornea. 

 The eye scales are simple 

 rounded plates. The pe- 

 duncles of the antennuhe 

 are nearly twice as long 

 as the eyes; the terminal 

 segment and the greater 

 part of the much longer 

 preceding segment ex- 

 tending beyond. The 

 peduncle of the antenna 

 reaches the base of the 

 cornea. The acicle is 

 straight on the inner side, 

 its margin being in line 

 with the point of the ter- 

 minal. A little below 

 this spine, on the outside, 

 is another spine, which 

 forms a fork with it. At 

 an equal distance below 

 this is a third spine of 

 equal size. Between this 

 and the base the margin is 

 concave. The armature 

 of the inner margin con 



sists of a comb of twelve or thirteen sharp spinules, which stand per- 

 pendicular to the axis of the acicle. 



The middle area of the anterior portion of the carapace is spool 

 shaped and is bordered by bunches of bristles; the sides of this portion 

 are cut by irregular depressions. The posterior portion is calcified. 



The chelipeds are bent downward as in Cancellm; the anterior mar- 

 gin of the carpus is raised in the form of a spiny crest, the spines 

 forming a continuous row with those of the hand; the summit of the 

 crest is armed with six spines divided into groups of three by a deep 

 notch; the largest spine is the third from the notch on the outside; the
