Collections were made from several points in this vicinity, 
but, though the conditions seemed favorable, the results were 
meagre. The forms actually observed are enumerated below, 
but no doubt the list might be largely extended. Probably 
all the forms found at Shippegan occur here as well.

Cocconeis scutellum Ehr. Gomphonema capitatum.
