[Vol. XLI 



Lahille describes a remarkable new genus of maekerel-like- fishes 

 from Argentina under the name of Chocnogastcr holmhenji. The 

 dorsal and anal fins are provided with finlets; llie mouth is very large, 

 and the body is covered with large scales. An alHed fish is described 

 by Dr. Lahille from Port L^'ttelton, New Zealand, under the name 

 of Lepidothynnus huttoni. Both of these are regarded, probably 

 correctly, as related to Gasterochisma mdampuft of New Zealand. 

 Figures of all three of these species are given by Lahille. 



In Volume III, of IMarine Investigations of South Africa (1905), 

 Dr. J. D. F. Gilchrist, Government Biologist of Cape Colony, describes 

 seventeen new species of fishes found in rather deep water off the 

 Cape of Good Hope. Several of these are most interesting additions 

 to our knowledge of fish-forms.
