The carapace is slightly carinate near the front ; the carina 

 extends to the rostrum; there is a small acute spine back of the 

 orbit and a dentiform angle at the lower anterior angle. 



The rostrum is short with a downward sloping upper margin, 

 bearing five or six teeth ; tip acute ; sides have a lateral carina 

 near the lower edge, which sometimes has a very small tooth near 

 the tip. The eyes are large and prominent, cylindric, facetted part 

 very convex, oblique ; there is a small prominent facetted papilla 

 at the apex. 



The antennules are very small ; the stalk is short ; basal article 

 with a wide stylocerite, having two subequal spiniform cusps ; the 

 outer branch of the flagellum is thick, with about six simple joints 

 bearing many long soft hairs ; at the sixth joint it branches, giving 

 off a slender outer flagellum composed of about seven elongated 

 articles ; beyond the branching the terminal part is small, composed 

 of about five or six obscure articles, which bear on the inner side 

 many soft crooked hairs. The inner flagellum is slender, a little 

 longer than the other, composed of about sixteen articles. 



The antennae are small, but larger than the antennules ; the stalk 

 is longer; the third article is cylindric; they are unequal; the 

 larger one has an obtuse outer distal tooth, bearing a cluster of 

 hairs (pi. 46, fig. i&) ; its flagellum is long and slender; its scale 

 is shorter and not so ovate ; it is equally wide at the widest part, 

 but tapers more rapidly, its widest part being at about the proximal 

 third (fig. ic') ; its breadth to length is about i : 2. 



The third maxilliped is very large, broad, foliaceous, convex, 

 and 5- jointed ; the principal part consists of the second and third 

 articles united by a distinct oblique suture, with a small sutural 

 notch on the inner edge. At this notch the marginal hairs or setae 

 change in form and size. The combined second and third articles 

 are broad, obovate, convex, and operculum-like ; when in place
