on the outer surface near the margin, while Ogilby described them 
as cycloid. This discrepancy is explained by the fact that they 
appear cycloid to the naked eye, the very minute teeth l^eing only 
visible under a microscope ; some scales, also, particularly in young 
specimens, are quite smooth. 
Nine specimens, 142-185 mm. long, are in the collection from 
Albany.

This genus is apparently distinguished from all others of the 
family Cheilodactylidae in having the cheeks naked. In its short 
and high anal fin, large scales, and general form, it appears to be 
related to Chirodactylns, Gill. ^ 
De Vis has described the teeth as arranged in sevei al rows in 
the upper jaw, and in one in tlie lower. Mr. Ogilby has, at my 
request, re-examined the type specimen in the Queensland Museum, 
and finds a band of villiform teeth in the upper jaw, which is much 
broader in front than laterally, and three series of small curved 
teeth in the lower jaw. In full-grown specimens the teeth become 
much more numerous.
