Thoracic seo-nients sul)-e()ual in length, the first heino- a little lonovr 

 than any of the others. The epiniera are l)roa(l 

 and short, with acute Literal angulations. 



The hrst abdominal segnunit hears suture lines indic- 

 ative of coalesced segments. The terminal segment 

 is sul)-triangular, with the (extremity produced and 

 deeply excavate, the excavation being v shaped. The 

 branches of the uropoda are similar in shape, the outer 

 one being somewhat longer; they are obliquely trun- 

 cated and do not ({uite reach the tip of the abdomen. 



Specimens were found ])y Mr. Henry Hemphill at No Name Key,

Head with a median projection on the anterior margin, produced 

 forward in the form of a large tubercle. Eyes colorless. First pair 

 of antennae reach the posterior margin of the head; Hagellum eight- 

 jointed. Second pair of an- 

 tenna? reach the posterior 

 margin of the tirst thoracic 

 segment. 



The segments of the thorax 

 are roughly granulated. A 

 transverse median ridge or 

 elevation appears on each of the segments, giv- 

 ing the dorsum, from a lateral view, a very 

 rugged appearance. The epimera are rough 

 and are drawn out laterally in very acute angles. 



The abdomen is composed of two segments, the first segment being 

 formed of several coalesced segments, as indicated by two suture 

 lines. In the center of this segmiMit are two longitudinal ridges, placed 

 obli([uely, so as ahnost to meet anteriorly and to spread apart at their
