AMBLYSTOMA TIGRINUM ON LONG 

 ISLAND. II. 



Records of Larvae. 



Investigation concerning the larval stages of 

 this species during the past season were restricted 

 to one station, namely the I. Hudson Estate near 

 Syosset, which comprises about 100 acres, situated 

 in the hilly or moraine region of Long Island. With 

 the highest elevation, about 200 feet on the western 

 part of the estate, drainage is through the eastern 

 part, where in meadow and woodland there are 

 several small permanent ponds and in the spring and 

 early summer numerous temporary pools. 



On the first visit to the region, May 31st, both 

 the ponds and pools were examined thoroughly, the 

 results showing an abundance of aquatic life, includ- 

 ing spotted and painted turtles, several species of 

 frogs, tadpoles, waternewts and a great variety of 

 aquatic insects. In addition some of the permanent 

 ponds have been stocked with gold fish; others con- 

 tain yellow perch and sunfish. Larvae of Ambly- 

 stoma, more or less common, were found only in the 

 temporary pools. This observation was verified on 

 subsequent visits. 



Condensed field notes and notes on captive 

 specimens are as follows: 



May 3 1st j 1915. Pools in woodlands, with very 

 muddy water on account of cattle, are swarming 

 with tadpoles of Rana sylvatica. Caught six larvae 

 of Amblystoma tigrinum from 2 to 3 inches long. In 

 color they are dark olive green above, heavily 

 mottled, and uniform dull white below. Fins on tail 

 and back are broad, blade-like and translucent. 

 Head is large, wider than body. Eyes prominent, 

 iris golden yellow, pupil black. Gills long and 

 feathery, three on each side, carried upright and for- 

 ward when the larvae are resting. Limbs on small
