NOTES ON CHILEAN FISHES. WITH DESCKIPTION OF A NEW 

 SPECIES OF SEBASTODES. 



BY JAMES FRANCIS ABBOTT. 



In the spring of 1897, Rear Admiral L. A. Beardslee, U. S. N., 

 then in command of the U. S. man-ofwar " Philadelphia," 

 secured in the harbor of Valjjaraiso, Chile, a small collection of 

 fishes which he presented to the museum of Leland Stanford Junior 

 University. Through the courtesy of Dr. C. H. Gilbert, the 

 writer was ofiered the opportunity of examining them. The 

 following species were noted : 



1. Potamalosa notacanthoides (Steindachucr). 



2. Clupanodon fimbriatus (Kner and Steindachner). 



3. Isacia conceptionis (Cuv. and Val. ). 



4. Genypterus chilensis (Gay). 



5. Prolatilus jugular is (Cuv. and Val.). 



6. Hippoglossin.a macrops Steindachner. • 



The last-mentioned species has heretofore been known only from 

 Steindachner' s original description . and excellent plate and from 

 Giinther's single allusion unaccompanied by description. The 

 specimen at hand agrees with the description of H. macrops so 

 exactly in every detail as to leave no doubt whatever of its iden- 

 tity. But the extension of the range of the species through such 

 a very great distance as that from Mazatlan to the Strait of 

 Magellan is hardly probable, and it is more than likely that the 

 fish described by Steindachner did not come from Mazatlan at all, 

 but from far down the South American coast. This idea will be 

 accepted the more readily Avhen we recall the remarkable jumble of 

 species attributed to the fauna of Mazatlan by the same author,' the 

 result of a collector's transposition of labels, and later corrected 

 by him. We may also consider the fact that in all the extensive 

 collecting that has been done on the Mexican and Central Ameri- 

 can coast in recent years, no specimen of this well-marked species 

 has been found.
