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, as in 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 ofl^. 



The specimen is only 4 millim. long, and has the same breadth. 

 Forcellana corallicola has hitherto been recorded only from 

 North-eastern Australia.

The collection contains twenty-five fine specimens, which 

 were found living on Pennatulce 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 epibranchial 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. Each 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
