^Minute adopted by the Executive Committee 

 of the New York Zoological Society, held on

 nine hundred and twelve. 



Resolved, That the Executive Committee 

 learn with deep regret of the death of Mr. 

 Hugh J. Chisholui, a member of the Board of 

 Managers since 1900. 



From the time of the early development of 

 the New York Zoological Park, when interest 

 and support were most needed, Mr. Chisholm 

 always displayed the keenest interest in tlie 

 great undertaking and readiness to assist in 

 its development in ever, way. He attended all 

 the meetings of the Board, and always expressed 

 great pleasure in the progress of the work. His 

 generosity and good-will were a source of 

 strength to the Executive Committee, and it is 

 with a sincere sense of loss that this entry is 

 made upon the minutes.

SPECIES OF FISHES IN THE WORLD 



Questions are frequently asked at the Aqua- 

 rium concerning the number of species of fishes 

 in this region, in North America and in the 

 world. In any locality where the fishes have 

 been well studied, it is an easy matter to answer 

 such a question. Thus, within fifty miles of 

 New York City there have been taken two 

 luindred and thirty-nine species, according to 

 Mr. John T. Nichols, of the American Museum 

 of Natural History, who has carefully collected 

 the records of occurrences. Of course, this 

 number may be increased slightly in coming 

 vears, especially by the capture of marine 

 wanderers accidental to our fauna. 



Tlie number of North American species can only 

 be estimated somewhat roughly at present, for 

 the reason that in many regions the fishes have 

 not been studied with sufficient care. Jordan and
