2 NEW SPECIES OF HERMIT CRABS—BENEDICT. 
4, Subgenus LABIDOCHIRUS. 
Typical species Hupagurus splendescens (Owen), 
Eupagurus with the manus of the left cheliped cylindrical. Under 
this section I have included but three species, the type, 4. mertensi 
Brandt, and EH. parvus nov. 
Subgenus BUPAGURUS. 
Eupagurus alaskensis. 
Anterior portion of carapace a little broader than long. Rostral tooth 
' produced to the base of the eye scales; lateral projections much less 
produced. Eye-stalks short and stout, constricted in the middle. The 
eye scales taper from the base to a blunt apex; the subterminal 
spine is conspicuous from above. The avicles of the antenne reach the 
proximal end of the flagella and are three-sided ; sides flat, iridescent. 
The inner marginis armed with from 12 to 16 short conical teeth, and 
is set with bunches of hair. 
The merus of the right cheliped is very stout and strong, and extends 
beyond the eye by about one-half its length. The carpus is armed on 
its inner margin with a line of stout spines; there are also two !ongi- . 
tudinal rows of spines on its upper surface; elsewhere thickly set with 
spiny granules. The hand is set with spiny granules forming a border 
on the outer margin. On the fingers the surface is very coarsely gran- 
ular. 
The left cheliped is much smaller than the right; its carpus has a row 
of strong spines on the inner margin, and a parallel row further down on 
the outer surface; otherwise it is set with spiny granules as in the 
large hand. The dactyl does not show from above any flattened sur- 
face, but from the prehensile edge to the outer margin it is evenly 
rounded. 
The ambulatory legs of the right side overreach the right cheliped 
but little; in very large specimens not at all. The upper surface of the 
merus joints are a little fattened. The upper margin of the carpus is 
armed with a single row of spines. Upper surface of propodal joints 
flattened, armed with a row of short spines on the summit and else- 
where with spiny granules. The dactyls are very wide, compressed, and 
twisted. The upper surface is convex, its summit and margins each set 
with arow of granules. Between these rows are long, smooth, surfaces. 
The inner surface of the dactyl is flat. The outer surface is very con- 
vex near the proximal end, but becomes much more flattened near the 
tip. 
In alcoholic specimens the general color above is a light purple with 
iridescent reflections ; below, light, tinged with reddish. A red streak 
runs around the prehensile edge of the thumbs and behind the dactyls 
to the inner margins of the hands, There is an oblong patch of red
