The segments of the thorax are distinct. The epimera are marked 

 off by faint lines or impressions. The abdomen is composed of six 

 segments, which are distinct at the sides but fused in the middle. 

 The posterior margin of the terminal segment 

 is broad, with a slight median excavation. 



The pleopoda consist of four pairs of single- 

 branched plates or lamellae, 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 lamellae. 

 These lamella consist of five 

 pairs of plates, the first pair of 

 which have the second segmentproduced distally in a linguiform process. 

 Color uniformly light yellow with small black dots on the incubatory 

 lamellae. 



Male unknown. 



Four specimens were found three at Puntarasa, Florida, collected 

 by Henry Hemphill, and one from west Florida, collected by Mr. J. B. 

 Henderson and Mr. C. T. Simpson, all parasitic on Urocaris longican- 

 data Stimpson.
