S. I. Smith— Crustacea of the Albatross Dredgings. 55 
A very remarkable case is that of Parapagurus pilosimanus, 
which was taken at fifteen stations and in 250 to 640 fathoms 
‘by the Fish Hawk and- Blake in 1880-’81-’82, and in great 
abundance at one station, in 319 fathoms, where nearly four : 
hundred large specimens were taken at once. All these earlier 
fathoms, but none of the specimens were associated with the 
same species of es ietiggad some eing in a very different 
intense edad crim 
The eyes of these abyssal species are even more remarkable 
than their‘colors, as the following list of the Decapoda and . 
larger Schizopoda taken below 2000 fathoms by the Albatross, 
with the notes which follow, will show
