does not reach quite so far as the ventral, which latter fin arises under the last few dorsa 
rays and reaches two-thirds of the distance to the base of the anal. The anal, when laid hi ’ 
reaches the base of the caudal, its base is 2 J in its height. Scales : the tiled row small, 110 
one-third of the diameter of the eye. Colours : silvery, darkest along the hack and upp el 
half of body, where most of the scales have black margins, thus causing small reticulations 
in the colour. Upper surface of the head spotted with black ; some dark spots on the dors 
fin, and sometimes a few light ones on the caudal.

This interesting skin has unfortunately had its anal fin removed, whilst the pharynx 1

It may he considered that as this fish differs from P. conirostris in the form of its m ^ v0 
and snout, also in the position of the ventral fin, it might form a new genus ; hut we 
yet much to learn of the mountain barbels ; perhaps a more extensive acquaintance 
diminish the number of genera into which they are at present subdivided. . . j; ] ie
