specimens are short and feeble, on large ones rather 

 large and stout. In the woodland or muddy pools 

 the larvae frequently come to the surface for air. 



In a deeper and clearer pool, in an adjoining 

 meadow, specimens of larvae ranging in length from 

 less than 2 to over 4 inches, could be readily dis- 

 cerned as they came up for air, though less frequently 

 than those in the muddy pools, or as they remained 

 stationary, supported by a blade of grass or some 

 other slight object, perhaps ten inches below the sur- 

 face. Averaging larger in size, the larvae in this pool 

 also display without exception, a brighter color of 

 olive green and their general appearance suggests 

 small pike. Only two specimens of moderate size 

 were captured. The entire catch of the day died on 

 the way home and has been preserved in fluid. 



June I'ftlt. Second Visit to Hudson Estate. 

 Water in the pools is much lower. Caught nine 

 larvae, 3 to 3% inches long, in muddy pools, and six 

 2% to 4 inches long, in clear pool. In an aquarium 

 at the Museum the larvae proved voracious feeders, 

 preferring tadpoles (Kana sylvatica) to earthworms 

 and caterpillars. Small larvae had to be separated 

 from larger ones of their own kind to prevent canni- 

 balism. 



June 19th. Largest larva measures 4V2 inches. 

 Absorption of gills is beginning. 



June list. Third visit to Hudson Estate ac- 

 companied by Mr. Deckert of New York Zoological 

 Park. 



Muddy pools in woodlands had dried up with 

 the exception of one, still containing a few gallons 

 of water. Two Green Herons and a number of 

 Purple Grackles were observed feeding at this pool. 

 The remaining water was alive with tadpoles, well 

 advanced in development, and larvae of A. tigrinum, 

 some with gills partially absorbed, others still normal. 

 32 were counted. Diligent search for specimens
