In allotting to this species a specimen about 4 mm long, obtained 
by Mr. Bell Marley from the sponge Cerao chalinus, I am relying on 
the variability which seems to prevail in this genus. Here the second 
gnathopods, while agreeing with the particular denticulation of the 
palm previously described, are much wider at the terminal tooth, so 
that the palm is less oblique and the hind margin longer than in the 
type. Also the second joint of the third pereeopod, though wider 
proximally than distally, is devoid of the abrupt narrowing remarkable 
in the form earlier described. The principal flagellum of the first 
antenne, imperfect in the type, is here ten-jointed, with accessory of 
four instead of six joints.

CHEIRIPHOTIS WALKERI, sp. nov. Plate XIII. 
This species is distinguished from Cheiriphotis megacheles (Giles) 
by the first gnathopods, which have a well marked emargination in 
the oblique, but well expanded, palm, and by the second gnathopods, 
in which the palm, instead of being cut into four or five well defined 
teeth, has only two of such a kind, and of these the outermost much
