covered with tubercles which are perforated by numerous setae. There is a 
high conical projection on each branchial region and another in the cardiac 
region. Rostrum large, projecting and pointed, armed above with three or 
four short radiating spines arising from one tubercle, of which the three 
upper are larger than the lower one. External antennae short, appendix of 
the second joint single, triangular, smooth below but armed above with four 
rows of spines, those on the sides being the longest. Feet studded above 
with setigerous tubercles. Chelipeds wide, carpus with a large triangular 
expansion on the inside, which is spined and tubercled above. Abdomen 
wide, formed of many plates.

This species much resembles the last, but in the chelipeds there is a 
deep smooth sinus below, with a corresponding but rather shallow sinus in 
the carpus of the second pair of feet. When the two sinuses are brought 
together a roundish canal is formed. 
One specimen collected near Victoria, B. C., and in the Provincial 
Museum. 
Genus Phyllolithodes Brandt. 
Bulletin Phys. Matheni. de l’Acad. , St. Peters., 1849, VII., 175. 
Upper part of the frontal rostrum compressed, somewhat four-angled, 
greatly exceeding the hooked and pointed lower part. The upper margin is 
bidentate and the teeth blunt. The appendix of the second joint of the 
external antennae is divided into three leaflets oblong-linear in shape, rather 
wider at the apex and arranged in the manner of a fan. The fourth and 
fifth joints of the external antennae are destitute of spines. The thorax is 
triangular, rather long, and very high. Carpus of the first pair of feet is 
scarcely cristate.

Petalocerus Beilianus White. Proc. Zool. Soc. , 1856, 134. 
Although resembling Rhinolithodes in shape and appearance, its generic 
characteristics are well marked. The want of elongated granulose papilli, 
&c., on the feet, forms a good ’ distinguishing feature. Length of thorax 
1" 10"' to IF"; width 1 " 8 ". Victoria, Middleton, &c.

Genus Rhinolihodes Brandt.

Upper part of the frontal rostrum conical, obtuse, not dentate above, 
nearly equalling, at all events not exceeding in length the lower hooked part. 
The appendix of the second joint of the external antennae is triangular.
