Prof. Jungersen, very difffcult to see. — The ventral surface 
has 6 lamellæ (one for each of the 6 pairs of pereiopoda) and a 
large scutum (on the abdomen). The pereiopoda are thick and 
apparently immobile; on the innerside close to 
the tip they have a little bud-like process. When CE. 
made transparent the pereiopoda of the next larval 
stage are to be seen through the skin, and within 
the bud-like process a claw is seen, quite as in Acanthephyræ, 
the adult animal (fig. 21). There are 5 pairs of larva. A pereiopod. 
cleft pleopoda; they have a constriction about midway "and are 
perhaps 2-articulated; but the articulation is not distinct. They 
have rather long natatory setæ. The uropoda are cleft, unarti- 
culated and have no setæ. 
It has been found unnecessary to give a longer description, 
all details being seen from the figs.

The total length 7 mm. ) 
The body is very slender. The carapace inclusive of the ro- 
strum is about one third as long as the; total length. Rostrum is 
half ås long as. the carapace; it is slender and spiniform, without 
any denticles. In the- middle of the dorsal surface of the carapace 
there is a little blunt prominence; the antero-lateral corners are 
apically pointed. The posterior division of the body has 6 seg-
