NO. 2112. AN ALBINO SALAMANDER— BANl' A AND OORTNER. 379 



Desmognathus, and other colorless amphibian eggs which produce 

 pigmented larvae. During the season of 1914 Prof. T. H. Morgan, 

 of Columbia University, procured pigmentless eggs of the common 

 toad and kept them through their development until they were nearly 

 ready to transform. Early in their development they acquired the 

 normal pigment for toad larvae. The larvae were distributed in 

 convenient ponds at Cold Spring Harbor in the hope of finding more 

 of the same sort of eggs again. 



A number of cases of albino anurans have been reported in European 

 species. Pavesi ('79) and Boulenger ('97, pp. 28-29) report such 

 ^ases and review a number of those reported by others. These albinos 

 mclude larvae of Rana esculenta, larvae and adults of Rana tem- 

 poraria, a Bombinator imchypus, larvae of Biifo viridis, and larvae and 

 adults of Alytes ohstetricans. Of the last-named species Heron-Royer 

 ('86) reared adult albinos from albinotic larvae and in turn got off- 

 spring of the same sort from them. Most, at least, of these albino 

 anurans were unquestionably xanthic specimens, possessing abundant 

 yellow pigment, as our Spelerpes did.
