millimetres in length : the colour of the body is 

 brown, streaked with black, and the skin is ex- 

 tremely mucous or slippery. When dead, the 

 Colour frequently changes to a pale blue: there 

 is no particular appearance of a lateral line, except 

 what results from the longitudinal trace between 

 the dorsal and lateral muscles. 



The Count de Cepede farther informs us that the 

 above species, in the manuscripts of Commerson, 

 its first describer, is considered as a distinct genus, 

 under the name of Alticus, and called Alticus salta- 

 torius, but that it is a genuine species of Blenny. 

 The gill-membrane has at least five rays : the dorsal 

 fin has thirty-five articulated rays; the pectoral fins 

 thirteen; the ventral two filiform rays; the anal 

 twenty-six, and the tail, which is of a lanceolate 

 shape, ten rays.
