hoppers, spiders, etc. On one occasion a small wasp was released 

 in the cage and at once began to buzz about or run up the sides of 

 the cage actively. It was but a few moments ere a specimen leaped 

 eagerly and captured the prey. Then a most interesting performance 

 took place. No sooner was the wasp seized than it was whipped 

 into the mouth, and in turn stung the frog; the frog in turn showed a 

 very lively appreciation of that fact, and made an apparent effort 

 to eject the creature; but the process of ingestion had gone too far 

 and deglutition was completed without further ado, nor did the 

 frog show the least further sign of distress. On another day the 

 operation was repeated and very much after the fashion of the 

 preceding. It may be doubted whether Amphibia show any particu- 

 lar discrimination based on that type of experience." 29 



Salamanders. — Albert M. Reese, in a paper on the "Food and 

 Chemical Reactions of the Spotted Newt, Diemyctylus viridescens," 

 says that the animals show no difference in reaction toward bits of 

 raw meat and earthworms nor to the juices from these substances. 30 



A specimen of hellbender (Cryptobranchus allegheniensis) which 

 ejected remains of a crawfish soon after capture, refused to eat any 

 of these animals placed in its aquarium later. 31 



Reptiles. 



Experiments in Asia. 



Among Frank Finn's many experimental contributions to the 

 theory of natural selection are two which deal with the food taken 

 by lizards. The first 32 deals with the Indian lizard (Calotes versi- 

 color), both captive and free individuals of which were offered a 

 variety of adult Lepidoptera. The results of feedings of the free and 

 confined individuals agree very well except in the case of butterflies 

 of the genus Evplcea. The record for these insects with lizards in a 

 cage is A 4 Rl, and with those unconfined, Al R4. Species of 

 Danais, Delias eucharis, and Papilio aristolochia> were freely eaten, 

 and Finn concludes: "The behavior of these reptiles certainly does 

 not appear to afford support to the belief that the butterflies, at any 

 rate, usually considered nauseous, are distasteful to them" (p. 48).
