no. sen STOMATOPOD CRUSTACEA — MANNING 25 



uropodal exopod with distal portion of proximal segment and inner 

 half of distal segment with scattered dark chromatophores ; distal 

 half of endopod dark. 



Discussion. — -These specimens agree in most details with Kemp's 

 (1913) account of the species, but differ in the following features: 

 (a) the rostral plate appears to be more elongate; (b) the branches of 

 the anterior bifurcation of the median carina of the carapace are 

 present although obscure; (c) the dactylus of the claw is curved more 

 strongly; (d) the posterior lobe of the lateral process of the seventh 

 thoracic somite is not acute but rounded; (e) the intermediate carinae 

 of the third abdominal somite and the lateral carinae of the second 

 somite are unarmed; and (f) the submedian dark squares of the fifth 

 abdominal somite are represented in these specimens by triangles. 

 Kemp noted that one specimen from Madras differed in these respects 

 from other material available to him. This species still is known too 

 poorly to determine whether or not these differences reflect normal 

 variation, or whether or not two or more species are present. 



Distribution. — Indo-West Pacific, from scattered localities be- 

 tween the Red Sea and Japan.

Holotype.— 1 9, 116.6; Baie de Tsimipaika, northwestern coast of 

 Madagascar; trawl; 15 m; muddy sand; A. Crosnier; March 1959; 

 USNM 124094. 



Description.— Eye large, cornea bilobed, set very obliquely on 

 stalk; prominent lateral projection present on each stalk; eyes ex- 

 tending to end of first segment of antennular peduncle; anterior 

 margin of ophthalmic somite obtusely rounded; corneal index 364. 



Antennular peduncle slightly shorter than carapace; dorsal pro- 

 cesses of antennular somite visible lateral to rostral plate as slender, 

 acute projections, directed anterolaterally. 



Antennal scale slender, curved, over one-half as long as carapace. 



Rostral plate subquadrate, as long as broad, margins sloping t<> 

 rounded apex; neither median carina nor median tubercle present; 

 lateral margins carinate. 



Carapace broad, anterior width more than one-half median length, 

 excluding rostral plate; anterolateral spines of carapace not extending 

 to base of rostral plate; anterior portion of median carina of carapace
