CLASS PISCES. 615 



There are some, whose tail, but little elongated, and 

 tolerably thick, is terminated at the end by a fin \ 



Finally, in some the body is very broad, in conse- 

 quence of the amplitude of the fins, and the tail very 

 short 2 . 



Anacanthus, Ehrenb., 



Resemble Pastinaca ; but their tail, long and slender, 

 has neither fin nor prickle. There is a species in the 

 Red Sea, the back of which is furnished with a 

 shagreen still larger than in the Sephen, and with 

 star-like grains 3 . 



o 



Myliobatis 4 , Dum., 



Have the head projecting from the pectorals, and the 

 latter more broad transversely than in the other rays, 

 which gives them somewhat the appearance of a bird 

 of prey, with the wings extended, and has caused them 

 to be compared to the eagle. Their jaws are furnished 

 with broad flat teeth, arranged like the squares of a 

 pavement, and of different proportions, according to 



grabatus, Geoff. Eg. Poiss. Bl. XXV. i. 1. N.B. The Lymne of 

 Lacep. I. iv. 2 and 3. is only a common pastinaca. R. Jamaicensis, 

 Cuv. Sloane, Jam. pi. ccxlvi. f. 1.

 Lesueur, Sc. Nat. Phil, or Micrura, Bl. Schn. 360. 



3 The Aiereba, Marcgr. 176. (Raia orbicularis, Bl. Schn.) belongs 

 perhaps to this subdivision. 



* MvXwfiaroc, from Mv\r? (a mill), in consequence of the form of 

 their teeth. Mourines is their Provencal name.
