a honeycomb-like cells. The distal half of the segment is armed 

 « with marginal spines, which are obsolète on the rounded 

 « posterior extremity (i) ». In E. intermedia the corresponding 

 part of the surface of telson has only an irregular row at each 

 side of less developed rounded impressions, a real constriction 

 is wanting, and the end, which is broadly rounded, is furnished 

 with several rather short spines. In E. australis the telson has 

 no dorsal cells or rounded impressions, it tapersfrom the middle 

 regularly to the narro wend which bears two rather long spines, 

 and several of the latéral spines along the distal half are conside- 

 rably longer than in the two other species. — Length of the 

 immature spécimen 2o.5 mm . 



Locality. — Stat. 1768, 1 spécimen. 



Remarks. — One might be inclined to think that the spé- 

 cimen described is only a small and therefore imperfectly 

 developed spécimen of E. sculpticauda , but it differs so 

 sharply in the features mentioned from an immature and only 

 a little larger spécimen of the latter species that it must be 

 considered a new forai.

Remarks. — This species was cstablished on a few spécimens 

 captured in the Gulf of Panama and near the Galapagos 

 Islands ; subsequently it has been found in the Indian Océan 

 (Alcock).
