NO. 2044. NEW PHILIPPINE CRABS— RATHBUN. 81 



is less convex in the distal half than in plicatum, so that the segment 

 is wider distally than in that species. 



Color. — In alcohol the carapace is blotched, and the legs finely 

 mottled, with dark on a light ground. 



SESARMA (PARASESARMA) MOLUCCENSE JAMELENSE, new subspecies. 



Type-locality. — Pomt Jamelo, Luzon, in river; taken in 20-foot 

 seme; July 13, 1908; 2 males, 2 females (1 male is type). 

 Type.— Cut. No. 45917, U.S.N.M. 



Dimensions. — Type male, length of carapace 10 mm., width 

 between antero-lateral angles 11.3 mm., width between postero- 

 lateral angles 10.8 nun., width of front 6.6 mm., length of propodus 

 of cheliped below 7 mm., same above 3 mm., height of same 4 mm., 

 length of merus of thu-d leg 7.7 mm., width of same 3.4 mm. 



This form differs from typical moluccense de Man,i m havmg the 

 carapace a little narrower m proportion to its length; in the front 

 also naiTower in proportion to the width between the antero-lateral 

 angles; in the 9 or 10 tubercles on the upper margm of the movable 

 finger bemg obliquely transverse mstead of longitudmal, each 

 tubercle trending forward or distally toward the uiside of the finger, 

 as in S. lenzii de Man.^ 



As in the typical species, the carapace is widest at the anterior 

 angles; the surface of the front bears an elongated transverse tubercle 

 near the lower margin on either side of the middle, and a round 

 tubercle underneath the outer corner of the postfrontal lobes of the 

 inner pan-; the upper margm of the arm has no subdistal spme, 

 only an obtuse tooth, the lower margin has a triangular expansion 

 with denticulate border, and a spme or sharp tooth at the angle; the 

 upper surface of the palm has two oblique pectinated ridges sub- 

 parallel to the posterior margin, the ridges bemg prolonged back- 

 ward by sunple granulated lines toward the articulation with the 

 carpus; in the female the ridges are more longitudmal; the merus 

 jomts of the legs bear a sharp spme on the upper margm; the abdomen 

 of the male is shaped as in S. lenzii.^ 



SESARMA (PARASESARMA) PANGAURANENSE, new species. 



Type-locality.— ?Sing2,uT2in River, Port Caltom, Busuanga Island; 

 December 15, 1908; 1 female ovig. 



Type.— Csit. No. 45909, U.S.N.M. 



Dimensions.— Type female, length of carapace 4.8 mm., width at 

 antero-lateral angles 6.5 mm., width at postero-lateral angles 5.6
