half of the lateral regions. Eyes reaching nearly to end of orbit, but 

 halfway between tips of first and second teeth. Front moderately 

 constricted, anterior edge truncate. Lower edge of orbit prominent, 

 crenulate. 



Upper half of outer surface of pahn granulate. Ambulatory legs 

 sparsely furnished with long fine hairs, most numerous on the mar- 

 gins of the fourth leg and the anterior margin of the merus of the 

 thii'd leg; a sharp subdistal spine on anterior margin of second and 

 third legs. 



Allied to M. hrevis (tIeThsty=2I. grandidierii Milne Edwards ^ 

 and to M. sulcatus Milne Edwards.^ M. hrevis lacks the row of 

 tubercles on the branchial region; the tooth at the antero-lateral 

 angle of the carapace is broader; the anterior margin of the merus 

 of the fu-st three legs is densely hairy. In M. sulcatus the eyes reach 

 beyond the carapace, the surface of the hand of the female is smooth, 

 the legs are unarmed.

Tijpe-locality. — Sandakan Bay, Borneo; in seine; March 2, 190S; 1 

 female, mature. 



Dimensions. — Length of carapace, 6 mm,; width of carapace, 9.4 

 mm.; thickness of body, 6.3 mm. 



Type.—Csit. No. 44549, U.S.N.M. 



Body very thick. Carapace very convex, short and broad, nearly 

 smooth, and naked; a broad furrow on the front is continued across 

 the gastric region; from each side of the mesogastric region a deep 

 narrow groove runs back on the branchial region to a point opposite 

 the cardiac region, where it turns outward and forward, forming a 

 loop. Orbit shallow, oblique, its upper limit indicated only by a 

 fine smooth rim as far as the tooth at the outer end; this last is very 

 obtuse-angled and bounded posteriorly by a shallow notch. The 

 orbit is on a much lower level than the apparent margin of the cara- 

 pace; this margin is partially indicated by a very fine granulated line, 

 which is present above the middle of the ocular peduncle, and also 

 about the antero-lateral angle. There is a similar granulated line 

 above the postero-lateral margin and the base of the last leg. Sides 

 of the carapace vertical and horizontally grooved. Front narrow, 

 deflexed vertically, lateral margins convergent, shghtly hollowed at 

 base of eye-stalks, extremity broadly triangular; surface smoothly 

 elevated along the sides, a circular elevation in the center of the 

 broad median furrow. Lower border of orbit finely crenulate.
