rounded, truncate or slightly emarginate at the tip. The caudal 
peduncle is compressed and from 1: to 23 times as long as deep. 
We can detect no scales 
on the young fish, but in the 
adult minute but well-deve- 
loped scales are present on 
the sides of the posterior 
part of the body. They are 
longitudinally oval in form 
and have the nucleus near 
TEext-F1G. 13.—Scale of Adiposia macma- the base. Their sculpture 
hont (X 35), from base of dorsal fin. consists of numerous coarse 
radii and circular striae, both 
of which occur all round the scale. ‘The scales are rather widely 
separated and buried in the skin. They appear to be much less 
conspicuous than in A. Jongicauda, Kessler. 
The following note on the colouration was made from living 
fish :—‘“* The loach is variable in colour ;- it is usually very pale 
olivaceous, fading to silvery white on the belly and irregularly 
spotted on the head and upper part of the body with a darker 
shade. In some individuals the head and body are pale yellowish 
without markings or with a faint marbling. All the fins are 
tinged with dull red, which is more intense on the caudal than on 
the others, and are as a rule obscurely marked with small dark 
spots. There is always a narrow dark vertical stripe at the base

of the caudal on its peduncle.” This description, which refers to 
young and half-grown fish, applies equally well to specimens 
carefully preserved in formalin and spirit, except that the olivace- 
ous and yellowish tints have faded and the reddish colour dis- 
appeared from the fins. 
The pharyngeal bones have the form normal in the Cobitidae, 
but are perhaps a little straighter than usual. There are about 
12 teeth arranged mainly on an almost semicircular prominence. 
In the adult they are all shorter than the smallest diameter of the 
bone and (except those at the lower end of the series, which are 
very small) almost subequal in length, those in the middle of 
the prominence being slightly enlarged. In the young the central 
teeth are relatively longer.
