PHRYXUS PAGURI. 241 
G. C. Hyndman, August 16, 1848, corrected by an ex- 
amination of Mr. Templeton’s specimens. 
The male is very minute, elongate-ovate, with the tail 
more slender and indistinctly articulated. In Rathke’s 
figure, the segments of the body are represented as 
much more widely separated from each other at the sides 
than in our specimen, the anterior lateral angle of each 
segment being rounded, and the middle of the hinder 
margin more rounded behind; the upper antenne are 
very minute and three-jointed, the lower pair are longer, 
and seen beyond the lateral margin of the head; the legs 
are small, terminated by a small ovate hand with a minute 
hook-like finger (dactylos). 
The female is large and unwieldy, with very large 
ovigerous scales. The body is but slightly unsymmetrical, 
nearly oval in form, with the ovigerous scales very large 
and thrown over the back, entirely concealing the body, 
limbs, and tail of the animal, where the latter is incurved ; 
the head is oval, with the inner antennz very small, com- 
posed of a thick basal joint and a minute terminal one ; 
the outer pair are much larger, apparently three-jointed, 
terminated by athin bristle. The legs are well developed 
on each side of the body; they are strong and terminated 
by an oval hand, having a minute emargination for the 
reception of a small finger. The tail is composed of 
four transverse segments, each furnished on each side 
with a pair of nearly globose lobes, fixed by short 
footstalks to a short and slender base. The tail is termi- 
nated by a small joint supporting a single lobe like the 
rest, so that there are seventeen of these appendages in 
all. 
Our figures represent the upper and under sides of the 
female, with the head, one of the feet, and a pair of the 
lobes of the tail, and the minute and slender male.
