CEPHALOPODA. 205 



The young in this Class are produced from eggs, 

 which are found adhering together in clusters of 

 diverse appearance in different species. Those of 

 the common Cuttle-fish (Sepia Officinalis) resemble 

 a bunch of black grapes, with their foot-stalks ; 

 while those of the Calamary (Loligo Vulgaris) are 

 enclosed in many long jelly-like tubes. The species 

 are numerous and are found in almost every sea, 



Octopus,* the Poulpe. 



In the first genus of this Class we find no external 

 shell, nor internal plate ; the sac, being likewise 

 destitute of fins, is a mere oval purse, capable of 

 being somewhat lengthened or contracted ; there 

 are eight arms, nearly equal, of great size, united 

 at the base ; the eyes are unusually small ; the ink- 

 bag is seated in the liver ; the suckers are disposed 

 in two rows along the under surface of the arms. 

 Notwithstanding the absence of any fin-like expan- 

 sion of the sac, it appears that the Poulpe has the 

 power of swimming with considerable rapidity by 

 working its long arms, and especially by flapping 

 the membranous disk formed by the union of their 

 bases. Yet its more usual mode of progression 

 appears to be by crawling upon its fleshy arms, 

 either at the bottom, or among the rocks of the 

 coast, in the recesses of which it lies in wait for its 

 prey. Crabs, Lobsters, and other Crustacea are 

 thus seized, and dragged to the crooked beak, against
