ME. E. J. MIEES'S EEVISION OF THE HTPPIDEA. 319 



In this variety the lateral lobes of the front are narrower, spini- 

 or tuberculiform, and project beyond the level of the median 

 lobes. The frontal margin in the adult is denticulated. The 

 striations of the lateral margins are smaller than in the typi- 

 cal variety, forming a very narrow marginal band. The ter- 

 minal joint of the second and third pair of legs is much more 

 strongly falcate, its distal half narrower, and its apex more 

 acute.

The characters of this variety are so marked in the adult that 

 I was at first inclined to consider it a distinct species ; but they 

 are much less evident in the young animal. Most of the speci- 

 mens I have examined are of the female sex ; but the characters 

 are not sexual, as there are adult females of the preceding variety 

 in the collection. It would appear, from the localities given 

 above, that the range of this form is equal in extent to that of 

 the typical variety. The largest specimen, that to which White 

 originally applied the name, is much larger than any other of the 

 genus which I have seen — the carapace having a length of If inch, 

 and greatest breadth of 1^ inch.

Body depressed, broad. Eront very broad, anterior margin 

 sinuated on either side of the very slightly prominent median 

 frontal lobe, which is less acute than in B. strigillatus. The 

 obliquely striated area forms a narrow marginal band on each 

 side of the carapace, and is but very little broader posteriorly. 

 Eye-peduncles short, projecting but very little beyond the penul- 

 timate joint of the antennules — which is scarcely visible from 

 above, beyond the frontal margin of the carapace. Anterior legs 

 of moderate length ; terminal joint slightly compressed, with two 

 strong oblique setose ridges on its extero-inferior surface. Ter-
