CRUSTACEA OF THE MEEGUI ARCHIPELAGO. 39 



mian regions and the inflected sides of the carapace are smootli ; 

 the latter are hairy on the posterior half, above the bases of the 

 legs. As regards the shape and structure of the outer foot-jaws, 

 this species fully agrees with Myom. granulosa. 



The anterior legs greatly resemble those of Myom. granulosa, 

 bat they are everywhere completely smooth, though sparsely 

 punctate. They are as unequal as in that species, the right leg 

 in all the specimens being largest. The upper margin of the 

 arm, which is fringed with short hairs, does not present a small 

 acute spine at its distal end. The internal angle of the wrist is 

 slightly prominent, rounded and obtuse. The larger hand is but 

 little shorter than the greatest width of the cephalothorax and 

 about twice as long as high. In the shape of the palm and of 

 the fi.ngers, and in the armature of the latter, this species closely 

 resembles Myom. granulosa. The ambulatory legs of both species 

 are very similar to one another, the three terminal joints being 

 rather hairy.

Menippe BumpTiii, Fabr., inhabits the Bay of Bengal and the 

 neighbouring seas, being recorded by Fabricius from the coast 

 of Tranquebar, and by Heller (as Menippe Belangeri) from the 

 Nicobar Islands, whereas the above described specimen was col- 

 lected by Mr. J. A. Kruyt on the coast of Atjeh (Sumatra). 



Genus Mtomenippe, Silgendorf. 



The genera Menippe and Myomenippe stand greatly in need 

 of revision, much confusion being still found in the synonymy 

 of their species. The genus Myomenippe chiefly difi"ers from 

 Menippe by the external antennae being quite excluded from the 

 orbits, the inferior margin of which is united with the upper 

 margin, as in the genus Euruppellia, Miers.
