process with a small acute tooth at its tip. The exopod is broader than in the two 

 preceding sjiecies. The cheliped of our single imperfect specimen is rather short and 

 stout, the ])alm comjiressed, with rows of granules on its upper edge and outer face. 

 The first pair of legs liave the merus granulated and with a stout tooth at the distal 

 extremity of its u^^per (or anterior) eJgc. The propodus and dactylus have each a few 

 serrations on the lower edge. The merus of the second and tliird pairs is granulated, 

 the granules becoming stout teeth on the upper and lower margins. The anterior crest 

 of the carpus has two 2)rominent teeth, with smaller serrations between. The propodus 

 is about two and a half times as long as broad, the upjjcr edge nearly straight, the lower 

 edge serrate. The dactylus is broad and has three or four coarse and somewhat irregular 

 teeth on its lower edge. There is no granulated ridge on the vmderside of the merus 

 of the second pair. 



The single, much injured, female specimen from which the above description is taken 

 agrees well with the description of Alcock and Anderson. The figure whicli they give, 

 however (taken from a larger specimen), diflFers in some details. The outer lobes of the 

 front are much less prominent, so that the front appears two-lobed ; the first lateral 

 tooth follows close upon the extra-orbital and is separated by a slight interval from the 

 second ; the granulation of the carapace appears to be less coarse, and mor(> restricted 

 to the prominent lobules.

A male specimen 55 mm. long is referred to this species. It is much smaller than 

 any of the specimens of A. affinis with which I have compared it, i)ut it agrees with 

 them in the characteristic points of the tuberculated eye-stalks and tlie bilobed cardiac 

 tubercle. As De Man points out, the eye-stalk carries a small tul)ercle near the tip in 

 addition to the large one at the middle of its length, and a small tubercle also lies behind 

 the bilobed eminence on the cardiac region. Our specimen has four granules on the 

 gastric region, two median and two lateral. The free part of the antenna is only a little 

 shorter than the carapace. The neck is rather longer than in tlie type specimen, and the 

 carapace as a w^hole is a little narrower. As in Miers's account, the merus of the cheUpeds 

 is " somewliat trigonous," rather than " fast cylindrisch " as De Man describes it.
