COPEIA 81 



were identified by me as the spotted-fin shark, Car- 

 charhinus limbaius, and this identification has been 

 confirmed by Mr. J. T. Nichols. The largest fish, a 

 female, approximated seven feet, while the smaller, 

 a male, accurately measured, was 6 feet, 4 inches. 

 This appears to be the second record of this species 

 for Long Island, and is therefore worthy of note. 

 About September 1, I examined four other sharks 

 of this same species at Montauk Point, where they 

 had been taken by fishermen some days before.

GROUND SHARKS. A CORRECTION. 



In Copeia No. 35, p. 70, second paragraph, for 

 "only 7 were males" read "only 8 were males." In 

 the last line of same paragraph after 8' 2" insert 8' 1". 

 Foot of p. 72 for "five of the seven" read "six of the 

 eight." The C. obscurus, measurements of which 

 were given on p. 73, was by editorial error omitted 

 from the record on p. 70. — J. T. N. 



HABITS AND BEHAVIOR OF THE TEXAS 

 HORNED LIZARD, Phmjnosoma 



cornutum, Harlan. I. 



Unlike the desert species of the genus, these 

 forms are far more active in the middle of the fore- 

 noon than during the hottest part of the day, which 

 lasts from about noon to the middle of the afternoon. 

 In the forenoon, Phrynosomas are actively feeding, 

 and the collector finds them readily. Their favorite 

 haunt seems to be along the edge of thick vegetation. 

 In such a place, during the feeding hour, they may 

 be seen running rapidly up and down, often passing 

 each other; and snatching with their viscid tongues 

 any insects which emerge into the open. The next 

 most likely spot is in the thick vegetation near some 

 ant road.
