FISHES OF NEW YORK 613 







In the vicinity of Woods Hole Mass, according to Dr Smith, it 

 occurs every year; some years rather scarce, some years abun- 

 dant. In 1897 it was extremely numerous in July and August, 

 and several hundred were often taken in one day in the seine. 

 It may often be obtained under gulf weed, but is usually most 

 plentiful in eelgrass and rockweed. No large fish are observed, 

 the size ranging from 1 inch to nearly 4 inches. The smallest 

 are rather uniformly dull brownish or greenish yellow in color, 

 but those 3 or 4 inches long are mottled with white and several 

 shades of dark green. In aquaria, small filefish often annoy 

 and injure other fish, biting their fins, eyes, and other parts. 



At Beesley's Point N. J. the writer seined an individual, Aug. 

 23, 1887, which had several parasites attached to the fins.
