BOPYRINA UROCARIDIS, new species. 



Body of female twice as long as wide 



Head with frontal margin produced in a broadly rounded process. 

 Eyes present about the mid- 

 dle of the head as small black 

 spots. 



The segments of the thorax 

 are distinct. The epimera 

 are marked off by faint lines 

 or impressions. The abdo- 

 men is composed of six seg- 

 ments, which are distinct at 

 the sides but fused in the 

 middle. The posterior mar- 

 gin of the terminal segment 

 is broad, with a slight median 

 excavation. 



The pleopoda consist of 

 four pairs of single branched 



plates or lamelhv, each pair directed toward the median line. 

 There are no uropoda. 



The incubatory pouch is a large area on the ventral side 

 of the body, which is not closed over 

 by the incubatory lamellie. These 

 lamella? consist of five pairs of plates, 

 the first pair of which have the sec- 

 ond segment produced distally in a 

 linguiform process.
