PALAEMON PILIMANUS. 181 



65 mm. and 50 mm. loug respectively; of the larger leg 

 the arm is measuring 14 mm., the wrist 15 mm. and the 

 whole hand 27 mm., the palm which is compressed in pro- 

 portion of 3:4, having a length of 18 mm. — The 

 measures of the other leg are respectively: arm ll'/gj 

 wrist 12, hand 20 mm., of which 12 mm. for the palm. — 

 According to the description of Mr. Heller (it may be 

 allowed to say that the figure does not agree with the 

 description), the carpopodite should be almost as long as 

 the palm. The other legs do not reach the extremity of 

 the scale of the external antennae. 



The male specimen , collected by Mr. Bleeker , has a length 

 of 75 mm.; the rostrum projects scarcely beyond the pe- 



9 

 duncle of the internal antennae , and is — dentate ; the 



two posterior teeth of the upper margin are placed on the 

 cephalothorax , but the first tooth has the same situation 

 as in the male of Bezoeki. The second pair of legs have 

 a length of 60 and 46 mm. respectively; the measures of 

 the larger leg are as follows : arm 13 mm., wrist 14 

 mm., whole hand 27 mm., the palm measuring 19 mm., 

 the fingers being comparatively shorter than in the specimen 

 of Bezoeki ; the palm is also somewhat broader. The arm 

 of the other leg measures 10 '/g mm., the carpopodite 1 1 '/s mm., 

 the hand 19 mm., of which 12 mm. for the palm, the 

 fingers being also a little shorter. In a female specimen , 

 of a length of 65 mm., the second pair of legs measure 37 mm. 

 and 31 mm.; the rostrum agrees entirely with that of the 

 male specimen of the same locality. The arm of the larger 

 leg measures 8 mm., the carpopodite also 8 mm., the hand 

 14 mm., and the palm 8 mm.; the measures of the small 

 leg are respectively 6'/2, 7, 10 and 6 mm. 



The fingers are closely united to one another and are 

 armed only in the larger leg with very rudimentary teeth.
