about half way down the hands, which bulge, and are 

 rounded on the inside, but on the outside are straightish 

 or slightly waved, and rather sharply keeled ; the second, 

 third, and fourth pairs of legs are somewhat compressed, 

 and terminate in claws with foui' longish hooks on the 

 inside j posterior pair of legs folded over the back, nar- 

 row, with the second joint somewhat bent upwards. 



This curious species was dredged by Mr. MacgilHvray 

 off Cape Capricorn, in lat. 23° 25' S. long. 151° 12' E., in 

 15 fathoms, the bottom being muddy sand and shells. It 

 is allied to the species of the second section of the genus 

 Porcellana, as detailed by Professor Milne Edwards in the 

 second volume of the " Histoire Naturelle des Crustaces," 

 but has characters sufficient to constitute a new subgenus, 

 to which may be apphed the name Porcellanella. The 

 figure represents it of twice its natural size. 



P. S. — The figures have been carefully drawn from the 

 originals by Mr. WilHam Wing, so well known as a 

 Zoological Draughtsman, and will at once explain my 

 imperfect descrijjtions.
