SYSTEMATIC REPORT 57 



them are short and thick, showing a slight tendency to be arranged in series, but there is little difference 

 in their size. Among these spines there are longer spines which are soft and membranous and as these 

 are bent or twisted, the margin of the telson appears to be armed with a ragged short fringe. In the 

 middle of the apex there is a small rounded protuberance which may be a distorted spine (Fig. 6H). 

 Length of immature female, 41 mm. The oostegites are moderately large but the fringes are only 

 just beginning to develop (Fig. 6E).

Remarks. This species differs from all the other known species of the genus in the shape and arma- 

 ture of the telson. It resembles E. sadpticauda in having no long spines arming the apex but, although 

 the specimen is nearly adult, there is no trace of the constrictions and the sculpturing which are so 

 characteristic of sadpticauda. It might be thought that these features are not present because the 

 specimen is immature, but the length and proportions of the second to the fourth thoracic endopods 

 serve to distinguish it at once from sadpticauda. The specimen is in very bad condition and in
