the remarkable foamy "nest" of this species, with numerous small black 

 larva? just hatched. In raising a large flat stone in the shallow stream 

 I found a compact ball of snowy foam of a somewhat gelatinous con- 

 sistency. The ball was about 70 mm. in diameter, and through the 

 center there extended a canal about the width of a finger. In this 

 hollow the blackish larva? were located. 



The voice of this species is fairly loud for its size, and can be 

 expressed by the word " pink' 1 in frequent succession.
