Local Cryptogamic Notes, 
By Henry C. BENNETT AND SMITH ELY JELLIFFE. 
From observations made upon the local distribution of diatoms 
it would appear that Ammphipleura pellucida is not a common dia- 
tom. Its occurrence in a recent gathering from Van Cortland 
Lake has prompted the following note upon other forms found in 
the same gathering. The following forms have been determined: 
Amphipleura pellucida Kg. 
Amphora ovalis Kg. 
Cocconeis scutellum Ehr.
