PICKERING'S HYLA ACTIVE IN 

 JANUARY. 



On January 30, 1914, I heard two Spring 

 Peepers [Hyla pickeringii) singing at noon in a 

 swamp at Brookhaven, Long Island, N. Y. There 

 would be a series of half a dozen or more peeps 

 followed by a silenee of about five minutes; the 

 frogs responded twice to my whistled imitations of 

 their calls. The temperature of the air was 56° 

 E. in the shade; there was a gentle wind blowing from 

 the southwest, and the sun shone dimly through 

 fog clouds. Much ice was still to be seen on the 

 ponds ; the temperature had been warm for several 



days previously. FRANK OVERTON,

A NOTE ON THE PURRING GOURAMI. 



Although not as highly colored as most of the 

 Labyrinth-tishes from the Ear East, Ctenops vitta- 

 tus, commonly called the Purring Gourami, com- 

 mands more than usual attention because of its 

 being able to produce purring sounds. 



It is a small fish, seldom over 2 inches in 

 length, and not often seen in aquaria in this 

 country, as it is very delicate as regards changes 

 in temperature and handling. Only recently has it 

 been my good fortume to have a few pairs of them 

 for any length of time.
