carpus of the chelipeds : the clactyli are nearly straight. The 
posterior pair of legs are very short. 
The pleon of the female covers the whole of the narrow 
sternum between the legs ; the distal half is slightly broader 
and is medianly very prominent, the prominence broken by 
transverse, jagged ridges, which extend to the margins, and 
on the last segment have a radiate arrangement. In the 
male the pleon is very narrow, especially the distal half, the 
sternum showing a deep excavation between its last segment 
and the base of the buccal frame. 
Length of carapace, 19 mm. 
Breadth of carapace, 25 mm. 
Length of cheliped, 30 mm. 
Dredged by Dr. Verco, Investigator Straits, 20-30 fms. 
Types in Adelaide Museum. 
I am in doubt whether this species should not be placed 
in the genus Fartheno'pe, Fabricius, but its complete agree- 
ment with Thyrolavihrus, as presented by Miss Rathbun, has 
decided me here.
