JElopichthys. Dr. Bleeker corrects the characters of this genus, which he 
had established without knowing the species. Nederl. Tydschr. Dierk. 1864,

^ Pelotrophusy g. n., Gunther, Proc. Zool. Soc. 1864, p. 314 : distinguished 
from Leuciscus by the form of the anal fin, the anterior part of which is 
much elevated, whilst the posterior is very low, both parts being abruptly 
divided. — The genus is founded on two new species from Lake Nyassa, 
P. microlepis and P. microcephalus. 
Cobitis barbatula and C. tamia. The geographical distribution of these two 
species in Scandinavia is remarkable. The former species is entirely absent 
in Denmark and the Scandinavian peninsula, but common in Finland, whilst, 
on the other hand, C. tcenia is rare and very local in Finland, but generally 
distributed throughout Denmark and the southern half of Sweden. Malm-
