1Q2 DEMON RAY. 



extremely broad in proportion to its length : the 

 head, which is of moderate size, is strait or recti- 

 linear in front, each side projecting into a vertically 

 flattened and slightly pointed lobe or wattle of 

 nearly two feet in length, and giving somewhat the 

 appearance of a pair of horns : the eyes, which are 

 large and prominent, are situated on each side the 

 head, nearly at the base of each of the processes 

 above described, and the month, which is very 

 wide, is placed as in others of this genus, beneath, 

 measuring about fifteen inches in width : the pecto- 

 ral fms are of a subtriangular figure, curving down- 

 wards on each side, and terminating in a point : 

 the back is very slightly elevated into a somewhat 

 pyramidal form ; and at its lower part is situated 

 the dorsal fin, which is of a lengthened shape, and 

 inclines backwards : the ventral fins, in the speci- 

 men observed by Duhamel, were somewhat more 

 than a foot in length, and the tail, which was desti- 

 tute of any fin, was very slender, and measured 

 about four feet six inches in length: the whole 

 animal was every where covered by a smooth skin, 

 without any tubercles or spines : the colour was a 

 cinereous brown above, and paler or more inclin- 

 ing to whitish beneath. This species is an inhabit- 

 ant of the Mediterranean, Atlantic, and Indian 

 seas : it is said to be chiefly observed about the 

 Azores, where it is known by the name of Mobular,
