NOTES ON A COLLECTION OF FISHES FROM THE 

 ISLAND OF MINDANAO, PHILIPPINE ARCHI- 

 PELAGO, WITH DESCRIPTIONS OF NEW 

 GENERA AND SPECIES. 



BY HUGH M. .SMITH AND ALVIN SEALE. 



In 1903, through the courtesy of the Surgeon-General of the 

 United States Army, a collection of fishes was obtained for the 

 Bureau of Fisheries from the Rio Grande, on the island of Min- 

 danao, Philippine Archipelago. The fishes were collected in 

 Octol)er, 11)03, by Dr. Morse, of the medical department of the 

 Army, who was stationed at Cotabato, near the mouth of that 

 stream, and all of tlie specimens were secured at or in the vicinity 

 of that place. 



Tlie Rio Grande is a stream of considerable size which rises in 

 the central part of the island and flows southwesterly toward 

 Lake Liguasan ; after receiving the outflow of this large lake it 

 flows northwesterly and discharges through a delta into Illana 

 Bay. 



The collection is small and contains only 31 species, but these 

 represent 20 families. Four of the species have not heretofore 

 been descrilied, and two of these are made the types of new 

 genera. The native names of the species are given when known.
