lobe is well marked and has the edges rugose, almost tubereulate. The frontal lobe 
suture is distinct, as are also the corneal lenses. ‘The antero-lateral margin is less 
concave and the antero-lateral ‘‘angle’’ rounded and serrate. 
Pedunele of uropod half as long again as telson; rami as in female, save for 
an extra inner spine on first joint of endopod. 
Length 4 mm, 
Loc. Tasmania: off Babel Island, 0-50 metres (type male, ‘‘Warreen”’ 
Station 29, Jan., 1939). New South Wales: 5 miles off Eden, 60 metres, on mud 
(type female, K, Sheard, submarine light, Dee., 1943) ; Ulladulla, Brush Island, 
45 fath., in fine silt on flathead grounds (D. Rochford, Jan,, 1945). Types in 
South Australian Museum, Reg. No. C. 2337 and 2688. 
The type male, which is illustrated, has clear-cut large reticulations on the 
hinder part of the sides, but in another male (Brush Island) the edges run together 
to form irregular ridges as noted for the female. Evidently the somewhat irregular 
curinae consistently found in thig situation in such species as costata, turgida and 
lata are so derived. 
QYNODIASTYLIB STRUMOSA Sp. NOY. 
Ovigerous female. Integument moderately calcified and brittle; the surface, 
apart from the major tumidities, is slightly irregular and finely granulate; with 
seattered pellucid spots on thorax and most of pleon, while in certain lighting 
there is an effect of short irregular raised lines on carapace. 

Fig. 35. Gynodiastylis strwmosa, type female; lateral view 
und cephalothorax from above (x 28). 
Carapace relatively small, not quite two-sevenths of total length of animal 
and as long as pedigerous somites and first pleon somite together; it is half as 
long again as deep, somewhat depressed and widest across branchial regions, which 
are considerably inflated; there is a tumidity on each side below the frontal lobe, 
the surface of which is rounded and slightly elevated; below the dorso-lateral 
tumidity the side is concave, and inferior. to the depression is an elongate swelling, 
traversed by a low longitudinal ridge, not. very well defined; the rear of the
