also mere vestiges suspended to the sides of the snout, and the vomer 

 is the only representative of the upper jaw. Hard and indivisible 

 plates supply the place of teeth, four on the upper jaw and two on 

 the lower. The snout, supported like that of a Shark, projects for- 

 wards and is pierced with pores arranged in tolerably regular lines; 

 the first dorsal, armed with a strong spine, is placed over the pec- 

 torals; the males are recognized, as among the Squali, by bony ap- 

 pendages of the ventrals, which are divided, however, into three 

 branches, and they have besides, two spinous laminse situated before 

 the base of these same ventralsj a fleshy appendage between the 

 eyes is terminated by a group of small spines. The intestine of the 

 Chimaerse is short and straight, it is furnished, however, with the 

 spiral valve, as in the Shark. They produce very large coriaceous 

 eggs with flattened and hairy borders. In the 



CniMiERA, Cuv. 



Or true Chimaera, the snout is simply conical; the second dorsal 

 commences immediately behind the first and extends to the tip of 

 the tail, which is drawn out in a long filament, and is furnished be- 

 neath with another fin similar to the caudal of a Shark. But one 

 species is known. 



C. monstrosa, L.; BL, 124, and Lacep., I, xix, 1, the female; 

 vulg., King of the Herrings; the Chat of the Mediterranean. 

 (The Arctic Chimsera.) Two or three feet long, of a silvery 

 colour, and spotted with brown. From the Northern and Euro- 

 pean seas. In the 



Callorhynchus, Gronov. 



The snout is terminated by a fleshy appendage resembling a hoe 

 as to form. The second dorsal commences over the ventrals and 

 terminates opposite the beginning of the fin attached to the under 

 part of the tail. But one species is known, 



Chim. callorhynch., L.; Lacep. I, xii, a female. (The Antarc- 

 tic Chimaera.) From the South Seas.
