localities belong either all to L. major or some to E. major and others either to a 
hitherto undescribed species or that they are young specimens of FE. sculpticauda

Remarks.— As already mentioned in the ‘‘Siboga”’ paper EH. 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. sculpticauda 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
