posterior angles somewhat produced and spiniform, wherein they exhibit some approach 
to the allied Pugettia quadridens (De Haan), also from the Japanese Seas, in which the 
lateral expansions of the carapace are so far excavated that their anterior and posterior 
angles present the appearance of distinct spiniform lobes or teeth (whence the specific 
name).

Pugettia velutina, n. sp. (PI. VI. fig. 2). 
The body and legs are everywhere covered with a close-set, short, felty pubescence ; 
the carapace is subpyriform, moderately convex, its dorsal surface with several elevated 
rounded bosses or prominences ; the spines of the rostrum are rather less than half as 
long as the carapace, acute and divaricate from their bases ; of the dorsal tubercles or 
bosses, three are placed upon the gastric, one on the cardiac, two on each branchial 
region, and there are also three small median tubercles on the elevated posterior margin 
of the carapace, and two conical, acute, lateral spines on each side of the body, the 
anterior and smaller of which is situated upon the sides of the hepatic region and the 
posterior on the branchial regions ; the upper orbital margin is well defined, with a 
small praeocular tooth and narrow hiatus near the postocular lobe ; on the ptery- 
gostomian region is a flattened oval tubercle or prominence, and another above the 
bases of the chelipedes. The basal joint of the antennae is moderately dilated, longi- 
tudinally concave ; the following joints are slender and are not concealed by the spines 
of the rostrum in a dorsal view ; the ischium-joint of the outer maxillipedes is slightly 
concave longitudinally ; the merus-joint small, not notched at the antero-internal angle, 
where the following joint is articulated with it ; the chelipedes (in the female) are 
slender and rather longer than the carapace, the merus or arm slender and subcylindrical, 
with three small tubercles at the distal extremity ; carpus indistinctly carinated on its 
outer surface, palm somewhat compressed, fingers naked, regularly serrato-denticulated 
on their inner margins ; the ambulatory legs decrease successively in length from the 
first to the last, and are slender, with subcylindrical joints ; the dactyli not denticulated 
on their inferior margins ; besides the close pubescence, with which the whole animal is 
covered, the merus-joints of the legs bear tufts of longer hairs, placed at intervals 
along the anterior and posterior margins, and a few such hairs exist at the distal 
extremities of the two following joints and on other parts of the body. Colour (in 
spirit) light yellowish-brown.
