ON THE ONYKIA ANGULATA. 29/ 



process, as in the books, and also in the long and 

 broad pectoral and ventral fins. Likewise, a beauti- 

 ful individual of the genus Onykia, which appeared 

 to me to be of the same species as that which we 

 observed in the Atlantic ocean, and of which I have 

 given a figure, accompanied with a note, vol. ii. p. 

 99, of this work, under the name P. angulata. The 

 figure was engraved from a design made by Mr, 

 Petit, on board the Geographe, in the voyage from 

 Teneriffe to the Isle of France. 



The form of its body and of its tentaculse, having 

 a strong resemblance to those represented in that 

 figure of 0. angulata, leave me no room to doubt 

 that it is to the same species that this animal be- 

 longs. 



I much regret the circumstance of my not seeing 

 this specimen sooner, so as to have described it with 

 the preceding species ; and I profit by this occasion 

 to testify my acknowledgments to Dr. Hays, for 

 having communicated it to me as soon as it was at 

 his disposal, thus enabling me to add a more com- 

 plete description to the indication given in the first 

 part of this volume. This specimen serves, moreover, 

 to confirm the characters that I assigned to this ge- 

 nus, and also induces me to propose the following 

 generic divisions, viz. 



* Long arms, armed with hooks, accompanied by 

 suckers. 



0. carribcea belongs to this division. 



** Long arms, furnished with hooks, without 

 suckers at their lateral base.
