HALE—AUSTRALIAN CUMACEA 431 
Pedunele of uropod narrow, a little longer than telson and two-thirds as long 
again as rami, which are equal in length; first of the two segments of endopod 
with two inner setae and three-fourths ag long as second joint, which bears three 
long inner setae and a slender terminal spine almost as long as ramus; exopod 
with a few short spines on outer margin and two unequal slender distal spines, 
one of which is fully as lone as the tamus. 
Colour creamy with the faintly pearly appearance noted in all species of the 
genus. Length 3-15 mm,

The slender respiratory siphons lie for the greater part of their length beneath 
the pseudorostrum. Probably the long setae of the peraeopods are plumose but 
with the lateral elements so fine as to escape detection in the fouled condition 
which remains even after cleaning. Some examples have the granulation of the 
carapace a little more pronounced than in others; juveniles have the posterior 
peraeopods shorter and stouter than in the adult. 
Off Brush Island this species was taken in company with tenuipes but is at 
once separated by the more slender pseudorostrum and pleon, the less slender 
posterior peracopods with longer fringing hairs, and above all by the less dilated 
first and second joints of the peduncle of the first antenna and the very different 
proportions of the uropod,
