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 antennse 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 antennse 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 a thin 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.
