established for it a separate genus, which he has since 

 cancelled in the " Catalogue of Amphipoda " for the 

 British Museum. The first pair of legs have the hands 

 slightly dilated, and gradually increasing in diameter to 

 the palm, against which the finger, when shut, closely im- 

 pinges for the entire length. The second pair of legs have 

 the wrist dilated and continuous with the hand, which is 

 large, diagonally quadrate, the palm being oblique and 

 defined by an obtuse tooth. The third and fourth pairs 

 of legs are short and strong ; they have the thighs 

 dilated anteriorly. The fifth, sixth, and seventh have 

 the distal extremity of the sixth joints dilated so as to 

 increase their prehensile power, a circumstance which 

 suggests to us the idea that this imperfectly-examined 

 animal may belong to the genus Sunamphithoe. 



The two or three specimens of this species whicli we 

 have seeii are dried and imperfect ; they were sent to us 

 by the late Mr. Barlee, who obtained them at Penzance. 



The colour of the specimens is a tolerably fresh green, 

 spotted with rather large and distant black points, which 

 are most abundant upon the sides of tlu animal.
