Lambrus hoplonotus , var. longioculis, Miers, tom. cit., p. 23, pi. v. fig. 6, 1879. 
South of New Guinea, 28 fathoms, lat. 9° 59' 0" S., long. 139° 42' 0" E., Station 188 
(a female). 
This variety is best distinguishable by the subspiniform tubercles of the branchial 
regions.

Parthenopoides, Miers, Journ. Linn. Soc. Lond., tom. cit., p. 672, 1879. 
Carapace often crowded, subtriangulate, with the posterior margin nearly straight, 
and produced at the postero-lateral angles over the bases of the ambulatory legs. 
Chelipedes rarely spinose and of moderate length (rarely exceeding two and a half times 
the length of the carapace).

must, I think, be included in this subgenus.
