Head smooth above, covered with a thin skin ; also the bones on the 

 nape are covered with skin. Occipital process narrow, about four times 

 as long as broad ; basal bone of tlie dorsal spine elongate, triangular, nearly 

 as long as the occipital process, from which it is separated by an intersjjace. 

 Body luuch elongate, its depth being one-ninth of the total length without 

 caudal, the length of the head nearly one-fifth. Snout broad, obtusely 

 rounded, twice and a half as long as the eye, which is one-seventh of the 

 length of the head. Mouth inferior, as wide as the snoiit. Teeth on the 

 palate in an miinterrupted concentric band, which is narrower than that 

 of the inter-maxillaries. Barbels very thin, the nasal filaments extending 

 not beyond, and those of the maxillaries somewhat behind, the orbit. 

 Dorsal spine not serrated, lower than the body ; pectoral spine a little 

 longer, stronger, strongly denticulated interiorly. Adipose fin about as 

 long as anal. Caudal notched. Coloration nearly uniform.

 movable labial teeth nor a denticulated dorsal spine longer than the pectoral.

Head very broad and depressed, but little longer than wide ; its length 

 is one -fourth of the total (without caudal) ; the greatest depth of the body 

 is nearly one-sixth of the same length. Eyes very small, ahuost im-
