52 THE BEACHYUEA. 



Pilodius paumotensis, sp. nov. 

 PL 8, Figs. 2,ga,8 b. 



Surface covered with a thin coat of soft, downy hairs, some of which 

 are very long, and most of which proceed from fine granules. Carapace 

 | as long as it is broad, regions plainly demarcated. Front convex, with a 

 large, median U-shaped notch ; and at the outer end a small, inconspicuous 

 tooth. Margin of front and orbits granulate. The two notches in the 

 superior margin of the orbit are small ; the one on the outer side is deep 

 and V-shaped ; outer angle of orbit not prominent. Behind it, on the 

 antero-lateral margin, are 4 spine-pointed teeth ; the first is low, the other 

 three are of good size ; all have a few denticles on their sides ; the last two 

 teeth or spines are equally prominent, the carapace having the same width 

 at these points. Parallel to the posterior margin, a row of fine bead gran- 

 ules. The postero-lateral surface, over which the posterior legs fold, is naked 

 and crossed by transverse and granulated lines. The basal segment of the 

 antenna touches with its inner angle the bent-down angle of the front ; the 

 outer angle of the segment does not reach the end of the inner orbital 

 angle ; the flagellum stands in the orbital hiatus. 



Chelipeds unequal, especially in the <?. Exposed surface granulate and 

 hairy like the carapace, except the lower part of the palms, which is smooth 

 and naked. Anterior edge of arms granulate, and at the proximal extremity 

 one very short, blunt spine. A small spine at inner angle of wrist. Palms 

 stout, with convex lower margin. Basal half of dactylus rough and hairy. 

 Fingers gaping, prehensile edges with a few large teeth, tips very broad and 

 deep spoons. Ambulatory legs spinulous above. 



All the specimens in alcohol are covered on the dorsal aspect with small 

 dark color spots.

Distribution : — 



Fakarava Id., Paumotus; outer reef; Oct. 12, 1899; 3 <?, 3 ?. 



Makemo, Paumotus; reef; Oct. 21, 1899 ; 1 <J type, 1 ? (Cat. No. 32,852, 

 U. S. N. M.). 



This species has much in common with P. jmbescens Dana, 1 but differs 

 from it in having the carapace and chelipeds finely rough, instead of the
