Examination of the specimens of D. australiensis Haswell shows that in this species the epipodite is present. It seems necessary, therefore, to make a new genus for this species, and such others as may agree with it in this particular. The name proposed is Dromidiopsis. Characters of Dromidiopsis, n. gen. :- 1. Bostrum triangular, with the sides not distinctly lobed. 2. Carapace slightly longer than broad. 3. Sternal furrows in the female reach the chelipeds, converge, but do not join, and end in a single ill-marked tubercle. 4. Gills phyllobranchiate. 5. Cheliped with epipodite. 6. 4th and 5th legs (last two walking-legs) subchelate. 7. Uropods present and visible in dorsal view in the angle between the 6th segment and the telson. 3.
