about four feet across the "wings," had cephalic fins, 

 and lacked the serrated spine on the tail. The only 

 record heretofore published on the Devil Ray in Cal- 

 ifornia was based upon the stories of fishermen of 

 San Diego, and is given by Jordan and Evermann 

 (Fishes of North and Middle America, 1896, I, p. 

 92 ) . The present record is presented with the inten- 

 tion of corroborating the evidence of the occurrence 

 of this or a related ray on the coast of Southern Cali- 

 fornia.

AMBLYSTOMA OPACUM ON LONG 

 ISLAND. 



To the records of adults published in Copeia, 

 July 1, 1914, nothing has been added. 



Concerning the ova Mr. Deckert writes, Copeia, 

 March 24, 1916, that two egg masses containing liv- 

 ing embryos were found, September 25, 1913, under 

 bark in a dry pool near Silver Lake, White Plains, 

 N. Y. The larvae hatched one day after having been 

 placed in water. Observations made during the pres- 

 ent season support this interesting and exceptional 

 habit of fall ovulation for Amblystoma. 



While searching for the ova of A. tigrinum on 

 the Hudson Estate near Syosset, L. I., April 7th, 

 we found larvae of A. opacum , 1% to VA inches long, 

 in several of the temporary pools. It is obvious that 

 these could not have developed and reached their 

 present size from ova deposited in the same spring, 

 since the pools were ice covered up to nearly April 1. 



Sixteen of the larvae after having been placed 

 in a laboratory aquarium developed a disease (white 

 growth on gills) from which they recovered quickly 

 after a small quantity of salt had been added to the 

 water. They are feeding freely on earth worms, cut 

 into small pieces, and measure, May 4th, 1% inches
