side. The eye scales are tapering, with a blunt apex armed with several spinules. The peduncles of 
the antennae do not reach the cornea; the flagellum is about three times the length of the anterior 
carapace; it is strikingly colored with wide annulations of light and dark. The chelipeds are large 
and very rough; the right hand is the larger. The inner lower edge of the merus and the anterior 
margins are each armed with a row of spines. The carpus has a row of five spines with horny tiprs on 
the inner margin continuous with a similar row on the hand; the surface of the carpus is broken with 
swellings bearing small conical spines with horny tips; between the swellings are stiff bristles. 
Similar swellings on the hand are strongly tuberculous; some near the carpus are also spiny. The 
prehensile edges of the fingers of the right hand are blunt, without teeth or tubercles except near 
the tips, the fingers of the left hand are well provided with cutting teeth. The ambulatory feet are 
stout and about as long as the chelipeds; they are rough with spiny margins; the dactyls are stout, 
with dense rows of bristles above and below. 
Small specimens from Mayaguez and Boqueron Bay. 
PAGTJRIAS 1 new name. 
Since publishing the statement * 2 that “ it seemed necessary to change the name of the group of 
which bernhardus is the type to Pagurus ” I have not seen that the group long known as Pagurus has 
been yet supplied with a name. For this group I propose the name Pagurias. 
Pagurias insignis (Saussure). 
Pagurias insignis H. de Saussure, Mem. sur divers Crustaces nouv. du Mexique et des Antilles; p. 453 (37), Genfeve, 1858. 
The middle front is occupied by a lobe much shorter than the lateral lobes, which are situated 
between the eyes and the antennas. The latter project to a point on a line with the bases of the eye 
scales. The margin beyond the lateral lobes is straight and forms a right angle, with a rounded apex 
where it meets the side. The eye-stalks are stout, constricted in the middle, and in length, measured 
from the margin of the front, a little more than equal to three-quarters the width of the carapace. The 
eye scales are short and broad, with straight inner margins; the blunt tips carry several spines. The 
antennal peduncle equals the eye in length. The anterior part of the gastric area is inclosed by a rather 
deep semicircular sulcus and is divided on the median line by a short deep sulcus, which in some 
specimens is occupied by stiff 1 >ristles. 
The left cheliped is much larger than the right. Behind the thumb are numerous oblong 
tubercles surmounted by a comb-like crest of little tubercles; between the large tubercles are fan-shaped 
fringes of plume-like bristles, which are parallel to the surface; higher up on the hand the form of the 
tubercles is a little modified. The propodus and dactyl of the second pair of ambulatory feet on the 
left side are wide; a prominent ridge runs the full length of both articles. Tubercles of the same 
nature as those on the chelipeds run transversely across the outer surface, interrupted in the middle 
by a sulcus, at the bottom of which is a row of single tubercles. The fan-like arrangement of bristles is 
repeated here, but does not occur on the right cheliped or on any other ambulatory leg. 
This hermit is a most beautiful object. As preserved in alcohol, the ambulatory feet are banded 
with red on the merus and carpus; the comb-like tubercles are pink, the bristles of the left second 
foot and of the left cheliped are yellow, and the white tubercles of the fingers are marked out in the 
base with scarlet lines. 
This is one of the larger hermit crabs of the West Indies. Several fine specimens were taken at 
Arrovo. 
Genus CALCINUS.

The rostral point is very small and the lateral projections are even less conspicuous. The eyes are 
longer than the carapace is wide; the scales are slender and terminate in one or two slender spinules. 
iThe name is composed of the old .term Pagurus and the suffix icts, indicating resemblance of some kind or other; it 
was in very common use among the ancient Greeks, as exemplified in XipHias, Anthias, Asturias, and numerous other 
old names.
