the two varieties the females in the collection are to be referred, I refrain from applying 
to them distinctive appelations (see figs. 3, 3a). 
It is not necessary to repeat here what has been elsewhere noted of the variability of 
Eurypoclius latreillei, and the impossibility of distinguishing the various forms described 
as specifically distinct by the characters usually assigned to them. 
Specimens of Eurypoclius latreillei were obtained by the Challenger at the following 
localities : — 
Chiloe. — Off Cape Tres Montes, in 45 fathoms, lat. 46° 53' 15" S., long. 
75° 12' 0" W. (Station 304), a young male (var. a) ; also at Port William, the cast shell 
of a young male (var. a), with very small and slender chelipedes. 
Magellan Strait. — Station 312, Port Famine, 9 fathoms; three adult and two 
younger males (var. a) the young with longer rostral spines, which are slightly 
divergent at the apex, also three adult and one smaller male (var. /3), and three 
females. 
Station 313, lat. 52° 20' 0" S., long. 67° 39' 0" W., in 55 fathoms ; three small and 
young males (var. a), one having the apices of the rostral spines rather remote one from 
another; three males, adult, small and young (var /3), and seven females. 
Station 314 (between Magellan Strait and Falklands), lat. 51° 35' 0" S., long. 
65° 39' 0" W., in 70 fathoms ; a small female. 
Falkland Islands. — Station 315, lat. 51° 40' 0" S., long. 57° 50' 0" W., in 12 
fathoms ; an adult male (var. ft), and seven females (one a cast shell). 
Station 316, lat. 51° 32' 0" S., long. 58° 6' 0" W., in 4 fathoms; an adult male 
(var. a). Its dimensions are : —

I may note in conclusion that the specimens collected in shallower water (4 to 
15 fathoms), are generally much larger and more robust than the specimens dredged at 
greater depths (45 to 70 fathoms), with a much more hairy carapace and legs. An 
adult male, however, dredged in 55 fathoms (Station 313), resembles the shallow- water 
specimens in these particulars, which I am unable to regard as of specific importance. 
Eurypoclius longirostris, n. sp. (PL V. fig. 1). 
This form is distinguished by the remarkably reflexed rostrum of the male, which is 
bent upward at an angle of nearly 45° to the front, with the spines toward their apices 
laterally divergent from one another.
