Article VII.— FISHES NEW TO PORTO RICO. 
By Joun TREADWELL NICHOLS. 
During the past summer (July 8-August 5), the writer spent four weeks 
in Porto Rico studying its fish fauna, incident to a biological survey of the 
island being made by the New York Academy of Sciences for the insular 
government. It seems best to postpone full publication of results obtained 
until there has been opportunity for the assembling of more complete data 
and further study of material, but to list the 22 species, no definite record 
of the occurrence of which is given in ‘ Fishes of Porto Rico,’ Evermann and 
Marsh (Bull. U. S. Fish Commission for 1899 [1900]), is in order. Two of 
these 22 species are listed as new. Through the courtesy of the United 
States National Museum, and of Mr. Barton A. Bean of that institution, 
it has been possible to compare our specimens with material in Washington. 
Galeocerdo tigrinus Miiller & Henle. 
The writer was shown a tooth of this species in San Juan. This is good, 
though not unimpeachable, evidence of its occurrence here. It is probably 
rare. 
Carassius auratus (Linné). 
The goldfish is said to be abundant at Isabella, in the northwest corner 
of theisland. It has been recently placed in a small pond on the Governor’s 
estate in the hills above Guayama, where it seems to be doing well. 
Myrichthys acuminatus (Gronow). 
A single small specimen was dredged in Condado Bay, July 21. In life 
the body was grayish above, pale below, everywhere with small bright 
yellow spots, those on the back and sides the nuclei of larger pale circles. 
Dorsal narrowly tipped with dark and then white; anal with white. 
Sardinella sardina (Pocy). 
This species was the abundant herring in San Juan Harbor in July. 
Specimens were collected July 8 and 11.
