A specimen found in Elphinstone Island Bay doubtless belongs 
to Haswell’s P. corallicola, which has been more exactly described 
by Mr. Miers. It agrees with both descriptions except in the 
following details, viz. that the posterior margins of the wrist and 
of the hand of the anterior legs are not fringed with hairs, and 
that the ambulatory legs of the second and third pair are armed 
in the same manner as those of the first pair. The hairs of the 
wrist and palm appear to be worn off, asin the specimen described 
by Miers, in which the carpopodite had also lost its hairs, although 
the palm was still pubescent on its outer margin. I would also 
point out that the small spinules with which this animal is every- 
where armed may easily be rubbed off. 
The specimen is only 4 millim. long, and has the same breadth. 
Porcellana corallicola has hitherto been recorded only from 
North-eastern Australia.

The collection contains twenty-five fine specimens, which 
were found living on Pennatule in King Island Bay. 
This interesting species is easily distinguished by many striking 
characters from all other species of the genus. The form of the 
carapace, which is much longer than broad, the extreme smooth- 
ness of its upper surface and of the legs, the flattened tridental 
front, and the shape of the chelipedes and of the ambulatory legs 
are distinctive features of this species. The lateral margins of 
the carapace are rather acute, without an epibranchia] tooth. The 
chelipedes are a little unequal. The carpopodite is but little 
longer than broad, with smooth entire margins, and with a convex 
upper surface, smooth and shining to the naked eye, but covered 
in reality with minute transverse lines. ach hand is slender 
and elongate, with a convex outer and inner surface, the latter 
being ornamented at the distal half of the anterior side with a
