Lophomicippa, gen. nov. 
(Adgos, crest, in allusion to the legs; Micippa, a generic name.) 
Carapace suboblong, high, rounded behind; front broad, almost vertically 
deflexed. LEye-stalks long, corneae large, oval, chiefly ventral in position ; 
eyes filling the orbits, the margins of which are for the most part entire, 
the broad basal joint of the antenna bidentate. Antennae exposed, 2nd and 
3rd joints small. 
Buccal cavity widened anteriorly. Merus of outer maxillipeds broader 
than the ischium, its external angle expanded, and its internal angle notched 
for the insertion of the palpus. 
Chelipeds of adult 9 slender, feeble, shorter than the carapace. Legs 
diminishing rapidly in length, the merus joints broadly expanded, forming 
together a deep, continuous border around and below the sides of the cara- 
pace and concealing the chelipeds. 
This genus unites the most striking characters of Micippa Leach’ of the 
Indo-Pacific, and Hemus A. Milne Edwards’ of tropical America. 
It has the carapace of the former and the legs of the latter. The orbits 
of Micippa are more tubular, while the carapace of Hemus is strongly nar- 
rowed in front and the second and third joints of the antennae are very 
large.
