eight respectively, on the next seven; posterior extremity rounded,

The female differs from the male only in the posterior end of the 
abdomen, the final segment ending flatly with a fringe of hairs, and a 
pair of projecting gonopods, as in Boopia. 
Found on Macropus dorsalis (a Queensland species) in the Melbourne 
Zoological Gardens, Le Souef collection. The description and figures 
are from Le Souef’s type in our possession. 
Latumcephalum lesouefi n. sp. Figs. 2-3. 
Amongst the mounted material in the Le Souef collection was a 
slide containing three specimens of a Latumcephalum labelled L. macropus, 
from Macropus ualabatus, Victoria. We find, upon examination, that 
it is quite a distinct form, the main points of difference being in the 
shape and size of the plate covering the antennary fossa, the relatively 
broader abdomen, and distinctly wider thorax. We have named the 
species in compliment to Mr A. S. Le Souef, who is both the author of 
the genus and the collector of the species.
