Description. — The frontal plate (fig. 2a) is a very short triangle with the 

 margins somewhat sinuate; it terminates in a well-developed, slender rostrum 

 which is considerably or much longer tlian the breadth of secontl antennuhir 

 joint. The oblong dorsal area behind tlie frontal plate is considerably \aultcd 

 and the keel along this area and forward to near the middle of the rostrum, 

 is high; seen from the side with its upper margin al)ove the area mentioneil it is 

 considerably curved and even sometimes feebly angular. 



Eyes moderately large, black. — Antennular peduncles similar in both sexes, 

 moderately robust; first joint nearly as long as the sum of the two others, seen 

 from above (fig. 2a) a little more than twice as long as broad; the terminal lobe 

 is a transverse plate directed forwards and upwards, at the base half as broad or 

 more than half as l)road as the end of the joint, its outer margin is directed con- 

 siderably outwards, so that the terminal nuirgin is longer than the ba,se (fig. 2c) 

 and this margin bears a row of 'J-IO spiniform processes, tlie inner short, from 

 there increasing in length outwards with those at the outer margin long and 

 directed forwards and outwards. The second joint slightly longer than the 

 third, its upper distal margin distinctly obliciue, from near the outer sitle directed 

 somewhat forwards, at a short distance from the outer margin with a rather long, 

 a little curved, spiniform jirocess directed essentially forwards; a little behind 

 the terminal margin and rather near the inner margin projects another process 

 as long as, or longer than, the first named, and it is either simjjle (fig. 2c) or 

 bifurcate (fig. 2d), in the latter case terminating in two spines. Third joint 

 with the dorsal keel occupying nearly two thirds of the ujiper margin; seen 

 from the side (fig. 2b) high and, if fully de\eloped and preserved, with the uiiper- 

 most part projecting forwards as a small triangle, just below which the front 

 margin of the keel is considerably concave. — The antennal squama reaches the
