The extreme length of the carapace is nearly five-sixths the 

 extreme breadth. 



The carapace, the outer surface of the wing-like expansion of the 

 arm, the upper surface of the wrist, and the outer surface of the palm, 

 are covered with coarse tubercles, which become squamiform on the 

 posterior part of the carapace. 



The anterolateral border of the carapace is crenulate, and the 

 posterior border is finely beaded and quite unarmed. 



The clypeiform expansions are well developed, their extreme transverse 

 dimension being about two-thirds their extreme antero-posterior dimen- 

 sion: the free edge of each has about six strong teeth with beaded edges 



The pterygostomian regions have only a few scanty hairs. 



The front is emarginate, and projects well beyond the orbits, 

 forming a laminar rostrum. 



The endostomial septum extends vertically from the level of the front 

 to the level of the mouth : its anterior border is angularly convex. 



The wing-like expansion of the end of the arm is conspicuously 

 four-lobed : the crest of the palm is 6- or 7-dentate. 



Mergui, Andamans, Ceylon, Persian Gulf. 



In the young the tubercles of the carapace and chelipeds are 

 sharper and crisper, and the antero-lateral borders of the carapace are 

 sharply serrate. 



8. Galappa pustulosa, n. sp. Plate VI. fig. 1. 



Carapace subcircular, the clypeiform expansions consisting of five 

 short broad teeth, the last of which is in advance of the level of the 

 posterior border : its surface is covered with large bullous tubercles 

 arranged in seven parallel longitudinal rows : the antero-lateral borders 

 are smooth in their anterior half, crenulated in their posterior half : the 

 posterior border is bounded on either side by a faint prominence. 



The pterygostomian regions have a few scanty hairs. 



The front is sharply bilobed, its tip is not quite so broad as the 

 orbit, beyond the level of which it projects.
