localities belong either all to E. major or some to E. major and others either to a 

 hitherto undescribed species or that they are young specimens of E. sculplicauda 

 Faxon.

Sta. 4721. Jan. 1.5, 1905. Lat. 8° 7.5' S., long. 104° 10.5' W. 2084 fms., trawl. 2 adult females. 



Sta. 4724. Jan. 17,1905. Lat. 11° 13.4' S., long. 109° 39' \V. 1841 fms., trawl. 1 adult female. 



Remarks. — As already mentioned in the "Siboga" paper E. intermedia 

 is only the young, differing from large or adult specimens in having the telson 

 scarcely or not at all constricted a little before the tip and without any network 

 of ridges on a portion of its surface, furthermore by having the first pair of 

 thoracic legs somewhat less thick than in the adult, but yet much thicker than 

 in the three other species of the genus. 



As seen in the list, five females with marsupium have been captured. The 

 smallest female (from Sta. 4652) is only 30 mm. long, the largest (from Sta. 4724) 

 is 49 mm., the three other respectively 31.6 mm., 34.5 mm. and 36.5 mm. Faxon 

 has mentioned a female measuring 66 mm. in length. 



Distribution. — Faxon established E. sculplicauda on some specimens from 

 the tropical Pacific (the Galapagos, the Gulf of Panama, off Central America) ; 

 Ortmann (1905) enumerated two specimens from the Hawaiian Islands. It has 

 been taken by the "Investigator" in the Bay of Bengal, by the Prince of Monaco 

 in various places within the triangular area between Gibraltar, the Azores, and 

 the Canary Islands; finally West of the Hebrides and Southwest of Iceland 

 at Lat. 62° 25' N., long. 28° 30' W. (Ingolf-Exp.). 



It is interesting that all the specimens captured by the ".Albatross" at 

 the six Stations in depths from 300 fms. to surface are not full grown, while 

 one adult female is from 400 fms. to surface and the four other adult females 

 from much greater depths to surface. This seems to confirm my observations
