Actumnus obesus Dana, Crust. U. S. Expl. Exped., I, 244, 1852; pi. xiv, fig. 3, 1855. 
In most respects our specimens agree with Dana’s description and figures. Dana says, “Antero- 
lateral margin arcuate, almost entire, very faintly four-lobed, lobes minutely denticulate.” In his 
figure 3a no lobes are indicated. His type was considerably larger than the specimens in hand, 
which show plainly the 3 marginal lobes separated by narrow incisions. The point of each lobe or 
tooth is at its anterior end, and is marked by a little longer granule or spinule; the teeth project 
beyond the general marginal line only by the length of this spinule. The areolations are a little more 
plainly marked than in Dana’s figure.

Honolulu reefs (Miers, Alcock). 
This subspecies or variety, as also areolatus (noted by Alcock), has a very fine scurf-like pubescence 
on the upper surface of the chelipeds. This must be borne in mind in using Alcock’s key to the Indian 
species of Trapezia.
