260 Mr. E. J. Miers on Crustacea from 
Typhlocarcinus integrifrons, sp. 0. 
(Gels 2S cares, il) 
The carapace is transverse, granulated, convex longitudi- 
nally, with a short scanty pubescence on its upper surface, and 
clothed with longer hairs on the lateral margins and on the mar- 
gins of the legs ; the cervical and branchio-cardiac sutures are 
very distinct. ront somewhat deflexed, with its anteriormargin 
entire, straight, and clothed with long hairs, and rounded off on 
the sides towards the inner orbital angles. Antero-lateral 
margins arcuated, when viewed under a high magnifying-power 
appearing granulated, with obscure indications of division 
into two or three granulated lobes. Epistome very short. 
Postabdomen (of male) not as wide in its widest part as the 
sternum, with all the segments distinct, terminal segment sub- 
triangulate. The ocular peduncles lie closely within the orbits, 
which are widest internally, with granulated margins ; a wide 
hiatus exists between the inner suborbital angle and the front, 
which is filled by the broad quadrate basal (or second) joint 
of the antenne, which reaches to the front; the exposed joints 
of the antennal peduncle are slender and clothed with long 
hairs; the flagellum rather long and muitiarticulate, the joints 
clothed with very short sete; the outer maxillipedes are 
smooth externally, with scarcely any intervening hiatus when 
closed ; ischium rather broad, merus about as broad as long, 
not notched at its antero-internal angle, where it is articu- 
lated with the next joimt. Chelipedes (in the male) rather 
robust, pubescent; arm short, carpus without a tooth on its 
inner surface; palm short and broad, and rather convex, 
broader transversely than the carpus; fingers slightly 
arcuated, minutely toothed on their inner margins, which are 
hairy at base, and having a rather wide interspace between 
them when closed. Ambulatory legs compressed, with hairy 
margins and rather long and slender terminal jomts. The 
male verges lie in channels of the sternum, but are visible 
from above. Colour light fulvous-brown. Length of the 
largest example (a male) somewhat over 3 lines (7 millim.), 
breadth 4 lines (nearly 9 millim.). 
A second specimen (female) is of rather smaller size, with 
slender chelipedes, the fingers of which meet when closed. 
It is with some hesitation that I assign this species to the 
genus T'yphlocarcinus of Stimpson’s family Rhizopide, as 
but few ot the types to which it is apparently most nearly 
allied are represented in the Museum collection. The diffe- 
rent genera of this family described by Stimpson are appa- 
rently separated by characters of small importance. The
