Each has the meral article laterally compressed, the upper lateral 

 margin granulose and fringed with long setae. The carpus and pro- 

 podus are shorter, thicker, the upper carpal margin terminating in a 

 tooth that interfits with the proximal end of the propodus. The dactyl 

 is long, acuminate, dorso-ventrally compressed, fluted on its upper and 

 lower surfaces, which are widely triangulate. 



The eyes are set upon very long, slender, cylindrical stalks, that 

 have their jointed bases one on either side of the rostrum ; the cornea 

 is distal, lying beneath the anterolateral angle when retracted. The 

 cornea has its dorsal surface interrupted by a linear continuation of 

 the stalk which terminates in a blunt, rounded nodule distally. The 

 lower surface of the cornea is a large, elongate oval that tapers to a 

 short oval on the inner and upper surfaces. 



The antennulae are fleshy, short and fold transversely within the 

 fossett which is rather open and lies beneath the rostral margin. 



The antennae also are quite short, the basal article distinctly bent 

 and having the normal relation to the orbital sinus; the flagellum is 

 composed of about eight short rings, the free portion of the antennae 

 being about as long as the rostral margin.
