and one -fifth of the total. Snout somewhat prominent. A curved 

 tooth in both jaws. Orbital tentacle very small ; the interorbital 

 space is rather flat, and its width is nearly equal to the vertical 

 diameter of the orbit ; a low fleshy crest ou the head. The dorsal 

 fin commences in the vertical from the origin of the lateral line, is 

 scarcely notched, and not, or slightly, continuous with the caudal. 

 Yellowish, spotted and dotted with black ; two oblique dark stripes 

 below the eye.

The chief difference between the specimens from the fresh waters 

 of Italy, and the Bl. cagnota, Valenc, from the coast of Toulon, 

 appears to consist in the number of the manchbulary teeth. Bl. 

 vulgaris has from foui'teen to eighteen, Bl. cagnota from ten to 

 twelve. I should think this character of some importance if it 

 proved to be constant, because one of these fishes lives in fresh, the 

 other in salt water. The dorsal fin is generally not continuous with 

 the caudal, except in a slight degree in the specimens from Dal- 

 matia. I do not know whether the latter were taken on the coast or 

 in a freshwater lake.

The height of the body is contained five times and a quarter in 

 the total length, the length of the head five times to five times and 

 three-quarters. Snout obtuse, with the upper proiile very obUque. 

 The curved tooth in the upper jaw small, that in the lower of mo- 

 derate size. Orbital tentacle very small. The interorbital space is 

 flat, and its width is less than the vertical diameter of the eye ; no 

 groove or crest or fleshy protuberance on the neck. The dorsal fin 

 commences in the vertical from the pr^opercular margin, and has
