NO. 2135. NEW PHILIPPINE CRABS— RATHBUN. 531 



dactjdi of last three legs fringed with hair on inner edge. Dactyli 

 broader in their distal half than in hartschi, and horny tip shorter. 



The three spines of the first abdominal somite are larger and more 

 distant than in hartschi. The chief spine on the epimeral plates cor- 

 responding to the third and fourth trunk legs is larger than in 

 hartscM.

Carapace longer than broad, cervical groove A^ery deep, surface 

 covered with spines, interspaces smooth. The rostrum projects well 

 be^^ond the general outline and is strongly constricted between the 

 base of the lateral horns and the lobe of the inner margin of the 

 orbit; the median of the three slender horns is more than twice as 

 long as the lateral horns; all the horns are arched upward. The 

 hepatic region bears one large spine, against which the eye is re- 

 tractile, and several small spines and spinules. The gastric region 

 has a large curved median spine; behind it there is a transverse 

 groove, after which there is a much smaller median spine. Cardiac 

 region traversed by a broad, smooth groove through the middle, on 

 either side of which there is a large spine. Two spines on the pos- 

 terior border of the intestinal region and an ill-defined row margins 

 the branchial region; the posterior of these is largest and most 

 elevated. 



Eyes large and oval. The antennae fall short of the end of the 

 rostrum; basal joint spinulous, last joint of peduncle longer and 

 slenderer than the preceding. Outer maxillipeds similar to those in 

 the preceding species, the two principal joints spinous. 



Chelipeds not much stouter than the legs in either sex, spinous, 

 and hairy. In the male the superior length of the palm is nearly 

 twice the height and same length as dactylus ; in the female the palm 

 is narrower than in the male and is shorter than dactylus. Legs 

 very long and slender; first pair four and two-thirds times length
