ANOTHER RECORD OF AMBLYSTOMA 

 OPACUM FROM LONG ISLAND. 



During the summer and fall of 1916 several col- 

 lecting trips for the adults of the tiger salamander 

 were made, with rather negative results as regards 

 that species, but two adults with eggs of the marbled 

 salamander, Ambly stoma opacnm, were found by Mr. 

 J. M. Ketcham, of Glen Head, L. I. They were dis- 

 covered under logs in a dried-up pond on the Hudson 

 Estate near Syosset, and were kept in damp soil. 

 After several weeks Mr. Ketcham presented them 

 to the N. Y. Zoological Park, where the ova arrived 

 on October 31, in rather a dry condition, and shrunk 

 to about one-third of their original size. The writer 

 placed them into a small aquarium with four inches 

 of water, and after being submerged about 45 min- 

 utes, they began to hatch. The gelatinous cover had 

 absorbed the water, bringing the ova back to their 

 natural size, which was about 3-16 of an inch. With- 

 in an hour after beginning to hatch, all the larvae had 

 emerged. Of the 88 larvae hatched, 76 found their 

 way to the Rockefeller Institute, where Dr. Eduard 

 Uhlenhuth is using them in his experiments on the 

 transplantation of the amphibian eye and other bio- 

 logical work. A dozen were retained and are now 

 on exhibition in the Reptile House at Bronx Park.
