posterior pairs of thoracic legs and the abdominal appendages are very 
nearly as.in EL. bernhardus. / 
In life the general color of the exposed parts is pale orange, the tips 
of the chelx and of the ambulatory legs white, the eyes black. 
The eggs are very large, and few in number as compared with the 
ordinary species of the genus, being 1.0™™ to 1.1™™ in diameter in alco- 
holic specimens, while in H. bernhardus they are only 0.45™™ to 0.50™™ 
in diameter. 
Measurements in millimeters.

The females apparently never attain as large size as the males, but 
they do not seem to differ from them in the relative proportions of any 
of the cephalothoracic appendages. 
The accompanying list of specimens examined shows that this is one 
of the most uniformly distributed and abundant species in from 50 to 
400 fathoms from Cape Cod to the Carolina coast. I have already ex- 
amined specimens from more than three-quarters of the whole number 
of dredgings made by the Fish Commission during the past three years 
within this region and between these depths.
