The height of the body is one-fifth of the total length (without 

 caudal) ; upper surface of the head flat, or a little concave ; snout 

 obtuse ; the lower jaw exceeds the upper a little in length. The 

 upper caudal lobe equals the height of the body in length ; but the 

 lower is three-fifths longer. The diameter of the eye is one-third 

 of the length of the head. Base of the ventral nearer to the extremity 

 of the snout than to the root of the caudal. The height of the 

 dorsal is less than the length of the head, without snout ; com- 

 mencement of the anal far behind that of the dorsal. Pectoral 

 greyish-brown with a broad whitish margin ; ventrals whitish.

The length of the head is not much more than the height of the 

 body, and one-fifth of the total (without caudal) ; the diameter of 

 the eye equals the extent of the snout, and is contained thrice and 

 two-thirds in the length of the head. Dorsal fin not elevated, its 

 longest ray being about half as long as the head ; the ventral and 

 pectoral fins extend beyond the end of the dorsal and anal ; the origins 

 of the dorsal and anal nearly opposite to each other. Pectoral 

 brownish, with bhie spots, with the lower rays white, but without 

 white posterior border. Ventral black, with white margins. ( Vul.) 



Mediterranean and neighboiuing parts of the Atlantic.

 The height of the body is contained six times and a half in the 

 total length (with the caudal), the length of the head five times and 

 •d third. The length of the snout is four-fifths of that of the eye.
