14. Macrones pratii, sp.n. D.1/6. A.19. (Plate I. Fig. B.) 
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 the dorsal spine elongate, triangular, nearly 
as long as the occipital process, from which it is separated by an interspace, 
Body much 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 snout. Teeth on the 
palate in an uninterrupted 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. 
One specimen 8} inches long. Kia-tiang-fu, 1,070 feet, province 
Sze Chuen. 
M. Sauvage describes in Ann. Sc. Nat. 1874, i.p. 7,a Liocassis torost- 
labris which I thought might be our species, but the latter has neither 
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, almost im- 
mediately behind the upper lip. Barbels well developed, the maxillary 
and the outer one of the mandible are the longest, reaching to the middle of 
the pectoral fin, the nasal and the inner one of the mandible only half as 
long. Mouth wide, anterior, with the lower jaw a little longer than the
