that's it ; 



13, in this respect, that the colour 

 and eyes are on the left side. But 

 reversed turbots, and specimens 

 dark on both sides, are sometimes 

 found in the fish-markets. The 

 turbot has a tuberculous, dark 

 skin, with little star-like bones 

 embedded in it. In the sole, 13, 

 it will be observed that the dorsal 

 and ventral fins unite with the 

 caudal; but in the turbot, the 

 caudal fin, 19, is quite distinct. 

 The spinal processes, which run 

 straight from the head to the tail 

 of the sole, take a curious bend, 

 20, in the turbot. 



The tJiornbach (JRaia clavata),

 J® fins, which are 

 553 situated on 



the posterior 

 sides of the heads of fishes, here 

 spread out, and give an ap- 

 pearance of great breadth to the 

 body, 3, 3. They look like the 

 dorsal and ventral fins of the 

 previous examples; but, an ex- 

 amination of the head, 2, and 

 the relative position of the fins, 

 will at once show the latter to be 

 the pectoral. The skin is spotted, 

 and studded with spines and tu- 

 bercles, and the bony tail, 4, is 



covered with formidable spines, 

 and towards its extremity are 

 seen two small fins, 5, 6 ; these 

 are the dorsals of this species. 

 In this tribe the dark side is the 

 back, the white side the belly. 



We will now examine a form 

 differing materially from all the 

 previous ones. The hammer- 

 headed shark (Zygcena malleus*), 

 7, derives its name from the ham- 

 mer-like form of its head, 8 ; its

eyes, 9, are placed at each extre- 

 mity of the formidable head, the 

 mouth being underneath ; the pec- 

 toral fins, 10, are muscular, and 

 well-developed, looking like strong 

 arms attached to rounded shoul- 

 ders ; the dorsal fins, 11, are 

 thick and fleshy, and without 

 spines. It has a long tail, which 

 is as powerful as that of the 

 thresher, 10-351. This fish is a 

 native of the Mediterranean and 

 Indian Seas, where its ferocity is 

 frequently proved by attacks 

 upon persons bathing. It attains 

 a length of about twelve feet. 



The conger-eel (Anguilla con- 

 ger), 12, exhibits the general ap- 

 pearance of the eel, but differs 

 from it materially in size, some-
