Hum 1)1011(1, iiu'usuii'd IVoiii llie [\[m of the tiil)erck"s lo the vt;nlral tind anterior 

 margins respectively, and as deep as the femur; Hie joint is, looked al from in 

 front, from the base of the stalk to near the summit of the tubercle almost circular; 

 it is here distinctly rounded and gradually sloping towards the lip of the trochanter. 

 The femur, which has a fairly long, not very well marked stalk, is 25 longer than 

 broad and a little shorter and narrower than the tibia; the anterior outline is 

 from the base of stalk in the proximal two thirds slightly convex, almost straight 

 and then a trille concave; the posterior as well as the dorsal surfaces are not very 

 abruptly convex beyond the stalk and then very slightly so; the joint is distinctly 

 broader in proximal third. The tibia, which is 28 longer than the extremely 

 long and slender stalk, is 23 longer than broad; the anterior margin is beyond 

 the rather shallow notch of the stalk evenly and rather distinctly convex; the 

 posterior margin has, beyond the prominent condylus and separated from it by 

 an incision, a rather low, but elongate basal elevation, which through a shallow 

 concavity blends into the fairly well marked convexity of the joint i)roper; both 

 the ventral and dorsal margins are beyond the stalk, which is very abruptly 

 delined, almost oval as far as the former is concerned, or circularly convex basally. 

 The hand, which is a little longer than the tibia and almost 1-2 broader, is shorter 

 than the trochanter, 2-1 longer than broad, 19 longer than deep and IS longer 

 than finger; the chela is 32 longer than broad; the lateral outlines are beyond the 

 stalk fairly abruptly convex and then moderately so; the ventral and dorsal ones 

 are perpendicular on the stalk and then almost straight. 



Coxae. — The fourth pair of the coxae are triangular and enlarged towards 

 the extremity, being almost twice as long as broad ; the posterio-interior corner is 

 rounded, and the hinder margin is almost twice as long as the inner. 



Legs. — The hairs seem to be as in Ch. plebejus n. sp. (cf. p. 187) and a 

 "tactHe" is present at the base of the fourth pair of tarsi; the legs are very short 

 and clumsy. The trochantin of the first pair is wider than the femur proper; the 

 femur of the fourth pair of legs is 22 longer than deep ; the tibia of the lirsl pair 

 of legs is much (r2) longer than the tarsus, which is 41 longer than deep; the tarsus 

 of the fourth pair of legs is only a trifle (1"1) longer than the femur is deep. 



Colour. — The palps are reddish brown, and so is the head, but a little 

 lighter; the rest of the body is yellowish.

Leg 1: femur 0594 (0225), trochantin 0-135; tibia 0414 (0135); tarsus 0333 

 (0-081) mm.

 (0-108) mm. 



Material. — The Danish Galathea Expedition has collected a single male 

 at Nankovry, one of the Nicobars.
