regard them as distinct species, seeing that all their 

 essential characters are similar and constant. The 

 specific characters usually assigned to this Proteus-

 pre-opercle is oblique, the soft part of the dorsal fin 

 more than twice the length of the spinous, and that 

 the dorsal and anal fins terminate nearly in the same 

 line. 



The Ballan Wrasse is numerous in the seas of

 It is common on the more rocky coasts of England ;

 where it shelters itself among the larger kind of sea- 

 weeds, and feeds upon crabs and other crustaceous 

 animals. It takes a bait freely, and fishermen

 and then smaller ; whence they conclude that the 

 large fish assume the dominion of a district, and 

 keep the younger at a distance. The spawn is said 

 to be shed in the month of April ; and the young, 

 scarcely more than an inch in length, are seen about 

 the margin of the rocks, in shallow water, through- 

 out the summer. Dr. Pamell suggests that it may
