B. MAGELLAN STEAITS AND FALKLAND ISLANDS. 



The Fish-Fauna of Magellan Straits, to which must be joined that of the Falkland 

 Islands and of the littoral archipelago on the western side of the extremity of the South 

 American continent, bears a thoroughly antarctic character, closely resembling that of 

 Kerguelen Island. Although it has been well worked as lately as the year 1867 by 

 Dr E. 0. Cunningham in his " Notes on the Natural History of the Strait of 

 Magellan," it is still very far from being completely known, as may be seen from the 

 large proportion of novel forms discovered by the Naturalists of the Challenger Expedi- 

 tion, who dredged at thirteen stations (Stations 304 to 316), between December 31, 1875, 

 and February 3, 1876. 



Scyllium chilense, Guich. 



Having examined some specimens preserved in spirits in the Challenger collection, I 

 am able to correct two errors in my former description, which was drawn up from cbied 

 specimens. The nasal valve is provided with a cirrus which, however, does not extend 

 to the lip ; and the teeth of the lower jaw have more or less distinct lateral cusps. 

 Gray's Harbour, Messier Channel. 



Spinax granulosus, n. sp. (PI. II. fig. C). 



This si)ecies is distinguished especially by the structure of its skin, which is finely 

 granulated, the granules being serially arranged on the tail, where they appear rather in 

 the form of minute spinelets than in that of granules. The space between the nostrils 

 and the median line of the lower side of the snout, the circumference of the mouth, the 

 base of the fins, and the back of the tail, are naked. The snout is much j^roduced, the 

 symphysis of the lower jaw being midway between the end of the snout and the root of 

 the pectoral ; snout very obtuse in front, with the front nostril opening forward. The 

 first dorsal fin shorter than the second, midway between the second and the spiracle. 

 Second dorsal spine three times the size of the first, not much lower than the fin. The 

 length of the base of the second dorsal is one-third of the distance between the two fins. 

 Pectoral truncated l^ehind, extending backwards nearly to the first dorsal. Ventral 

 extending to below the middle of the second dorsal. Black ; hind margins of all the fins 

 white. South-west coast of South America. Length of specimen (male), 10^ inches. 

 Station 305 ; 120 fathoms.
