6G CRUSTACEANS OF THE 



middle of the outer surface. On the middle the gra- 

 nules have but a diameter of ^/^ mm., near the 

 upper margin and at the base of the immobile 

 finger they are a little larger, being '^j^ mm. 

 broad. Under a lens I observe moreover a close micro- 

 scopic granulation on the whole outer and inner surface 

 of the palm, as also on the lower border on which the 

 larger granules are absent. 



The outer surface of the immobile finger shows a longi- 

 tudinal furrow near the lower margin and a shorter one 

 at the base of the teeth, and the granulation disappears 

 gradually towards the obtuse tip (Fig. 2'*'); this finger 

 bears just in the middle a strong conical tooth, on either 

 side of which two smaller teeth are observed. The strongly 

 curved dactylus is granular at the base and bears two rows 

 of impressed puuctures; this finger is also bluntly pointed 

 and is armed with 7 or 8 low, obtuse teeth. The left 

 hand is considerably smaller, its horizontal length 

 measures indeed only two third of the greatest breadth of 

 the cephalothorax and this hand is a little more than 

 twice as long as high. The fingers are almost as long as 

 the palm and more sharply pointed at their tips. The immobile 

 finger carries five incisiform teeth that gradually decrease 

 in size, the dactylus is less curved, distinctly grooved and 

 its teeth are also incisiform, but lower than those of the 

 index. The outer surface of the palm is rather uniformly 

 covered with granules, all of about the same size, ^4 ^t^- 

 broad, and between these granules one observes under a 

 lens the microscopic granulation. The lower border of this 

 hand is a little concave in the middle. The wrist and the 

 arm agree with those of the other leg, also with regard to 

 the granulation. 



The short ambulatory legs resemble those of Menippe 

 Panope. Their joints are smooth on the outer surface, 

 only a little punctate, but their anterior margin is finely 

 granular ; the margins are a little hairy, mostly those of 

 the terminal joints that end into sharp horny claws.
