* In the ‘Proceedings of the Zoological Society, 1865, p. 296, I described 
the genus Platacanthus as new amongst the Loaches; however, the specimen sub- 
sequently turned out to belong to a known genus. Since then I described another 
species (1867, p. 941), as Platacanthus maculatus. As the genus Platacanthus 
is considered a synonym of Lepidocephalichthys, it becomes necessary to define 
and name the genus to which the latter specimen belongs. 
Genus JERDONIA, gen. noy. 
Body elongated. Barbels eight, one rostral, two maxillary, and one mandi- 
balar pairs. A free bifurcated suborbital spine. Dorsal fin elongated (thirty 
rays). Internal pectoral ray osseous. Origin of anal slightly posterior to the 
termination of the dorsal.
