 were obtained:

Psammobatis rudis, Giinther (P. scobina). 



Callorhynchus antarcticus, Lacepede (C. callorhynchus).

In 1871 to 1872, the 'Hassler', under the scientific direction of Louis Agassiz, and 



with F. Steindachner as ichthyologist, obtained some fishes from the Magellan district,

to the list in this paper : 



Cottoperca rosenbergii, Steindachner (C. gobio). 



Notothenia longipes, Steindachner. 



N. hassleriana, Steindachner (N. macrocephala). 



During the voyage of the ' Challenger' (1872-1876), under the command of Sir G. S. 

 Nares, several stations were made in the Patagonian region. The fishes were described 

 by Giinther (1880, 1887, 1889), and the following species added to the Patagonian 

 fauna : x 



Scyllium chilense, Guichenot (Scyliorhinus bivius). 



S. canescens, Giinther (Scyliorhinus canescens).

The S.M.S. ' Gazelle ' (1874-1876), under the command of Captain F. von Schleinitz, 

 visited the Straits of Magellan and the east coast of Patagonia. The zoological results 

 of the voyage were edited by Studer (1889), and the following species added: 

 Notothenia squamiceps, Peters. 



1 Some of the new species of fishes obtained by the 'Challenger' were described by Giinther in a pre- 

 liminary paper: 1878, Ann. Mag. Nat. Hist. (5) 11, pp. 17-28, 179-187, 248-251.
