In the male the whole surface of the sternum, except the seg- 

 ment belonging to the external maxillipeds, as also the ptery- 

 gostomian region and extreme base of abdomen, is finely beaded, and 

 the surface of the exognath is granular: in the female the outer border 

 of the endognath also is granular, and the basal abdominal terga. 



The exognath is not dilated in any part, and the buccal cavern is 

 narrowed in front and is at least as long as broad. 



The chelipeds in the male are less than twice, though more than 

 ]| times, the length of the carapace;" in the adult female they 

 are not much longer than the carapace. The arms are cylin- 

 drical and are roughly granular everywhere except a very small part 

 of the under and of the inner surface. The upper surfaces of the 

 wrist and hand are slightly granular along the inner half. The 

 hand is not greatly longer than broad. The fingers are as long 

 as the hand, and are strongly bent inwards, much as in PMlyra 

 globulosa, Edw. On the immobile finger in the male there is a strong 

 tooth, and on the opposed edge of the mobile finger a notch, beyond 

 which the opposed edges are denticulate. 



The abdomen of the male consists of 3 pieces, including a linear 

 basal piece and a small apical piece : on the large middle piece the 6th 

 tergum is marked by a shallow groove, and bears a stout median tooth 

 at its distal border. 



Diameter of carapace of male between 7 and 8 millim., of female 

 the same. 



Two males and four ovigerous females from the Mekran Coast, 

 25 fathoms. 



This little species bears a considerable resemblance to PMlyra 

 adamsii, Bell ; bat may be distinguished by its perfectly circular and 

 strongly convex carapace, by its short chelipeds, and by the stout tooth 

 on the abdomen of the male.

Carapace in the adult almost circular, moderately convex ; its 

 dorsal surface defined all round, behind the front, by an elegantly 

 beaded line ; its surface, to the naked eye, smooth and polished. 



The hepatic regions are defined by a slight dorsal acuminate 

 bulge, or wrinkle. 



The anterior margin of the front, which does not reach the level of 

 the anterior margin of the buccal cavern, is concave and deflexed in 

 the middle line, so as to appear somewhat bilobed, but the deflexed
