Antennular peduncle as in Arde indicus (Coutière, Alpheidae Mald. and Laccad. Archip. 

 1905, p. 864, Fig. 134a). Second article one and a half as wide as long, a little shorter than 

 the visible part of the first, third article as long as the two preceding taken together. Stylo- 

 cerite acute, reaching to the middle of median article, vvith the outer margin slightly bent. 

 Outer antennular flagellum with 6 articles before the bifurcation and but a little longer than 

 the peduncle; i st article very short, following a little longer or just as long as thick. 



Carpocerite stout, slightly longer than the antennular peduncle, a little more than twice 

 as long as thick ; flagellum rather slender, tapering. The scale of the scaphocerite is rather 

 broad, a little longer than the antennular peduncle, with the outer margin very slightly curved 

 and ending in a rather strong terminal spine which is twice as long as broad at its base. 



External maxillipeds as in Athanas, penultimate joint rather short, terminal joint pointed, 

 4-times as long as broad at its base. 



There is but one cheliped, the right, present. Ischium tolerably slender, almost 3-times 

 as long as thick in the middle and becoming thicker at the distal extremity. Merus a little 

 more than one and a half as long as the preceding joint, its outer face about twice as long 

 as broad in the middle ; this face rather rapidly widens from the proximal extremity to the 

 middle and appears, near the carpal articulation, but a little less broad than in the middle. 

 The upper margin is unarmed at the apex, but the lower bears in the middle 3 slender 

 S-like shaped and movable spin u les, nearly of equal length, and that measure about 

 one-sixth the length of the merus ; between the acute, dentiform, distal extremity and the third 

 spinule one observes 2 or 3 setae ; the distal margin that articulates with the carpus, shows 

 a small, triangular notch, situated a little nearer to the lower than to the upper margin. 

 Infero-internal margin unarmed. Carpus short, about as long as the ischium, cyathiform. The 

 chela is turned outward, the dactylus even slightly directed downward. The chela is one and 

 a half as long as the merus and the fingers are just as long as the palm; of the palm, 

 which is one and a half as long as wide, the outer (upper) and the inner (lower) margin are 

 entire, the latter carinate, but one observes on the upper (inner) surface a small, oblique 

 gr 00 v e, just behind the articulation of the dactylus. The fingers which are also distinctly 

 compressed, shut close together and the pointed tips are crossing one another ; the dactylus 

 appears a little less broad than the other finger, its cutting-edge is very finely denticulate 

 from the articulation to near the tip, but the cutting-edge of the immobile finger is entire. 



Second legs as in the genus SynalpJieus. Merus 5-times as long as wide and nearly as 

 long as the carpus. First segment of the carpus 3,6-times as long as thick distally ; following 

 segments, taken together, 1, 3-times as long as the first, the second, the third and the fourth 

 are equal, slightly broader than long, each measuring one-fourth the length of the first; fifth 

 segment a little more than half as long as the first. Chela slightly more than twice as long as 

 the fifth segment, fingers as long as the palm. 



Ischium of the three following legs with a small, movable spinule near the base. 

 Measurements of the third legs: merus 2; carpus i; propodus 1,33. The merus is unarmed 

 at the distal extremity of the lower margin and 3,7-times as long as wide. Carpus unarmed, 

 3,1-times as long as thick distally. Propodus also of a stout shape, 4,66-times as long as wide,
