This species is characterised mainly by the irregular form of 

 the eyes, and the shortness of the peduncles of the antenna). 



Leucothoe nova3-hollandia3, sjj. nov. (PL XX., fig. 2.) 



Body thick. Pleon considerably shorter than the pereion. 

 Cephalon small ; first segment of the pereion very broad, tumid. 

 Eyes oval. Superior antenna) a little longer than the cephalon 

 and first segment of the pereion ; first two segments of peduncle 

 subequal — the second slightly longer than the first — the third 

 about one-third of the length of the second ; flagellum as long as 

 the last two segments of the peduncle, very slender. Inferior 

 antenna) subequal with superior ; flagellum very slender, rather 

 longer than the last segment of the peduncle. Maxillipedes with 

 a strong dactylos and well-developed squamiform plates — those of 

 the basa united together in the middle line. Anterior gnathopoda 

 large, complexly subchelate ; carpus much larger than the 

 propodos, irregularly triangular — the proximal (apical) and 

 superior angles rounded off, the iiif ero-distal angle produced into 

 an incurved pointed process, about one-half as long as the rest of 

 the segment ; propodos less than two-thirds of the length of the 

 carpus, rather longer than broad, terminating in a straight edge, 

 its dorsal border concave, ventral convex and closely applied to 

 the inf ero-distal process of the carpus ; dactylos absent. Posterior 

 gnathopoda simply sub-chelate, with a small meros, a sub- 

 triangular carpus, slightly produced at both of its distal angles ; 

 the propodos large, more than twice as long as broad, its dorsal 

 border convex in its proximal two-thirds, concave near the distal 

 end, ventral border slightly convex ; palm oblique, slightly
