PLANKTON OF THE GULF OF MAINE 
311 
The most abundant congregation of S. elegans so far encountered in the gulf 
was approximately 5,000 per square meter (young stages) over the outer part of the 
shelf off Nantucket on July 25, 1916 (Station 10354). S. elegans is far less abundant 
along the coast of Maine east of Cape Elizabeth, and off western Nova Scotia it is 
often so rare that the vertical nets failed to take it, though it might occur in the 
horizontal hauls. It is frequently as numerous as 50 per square meter in the Bay of 
Fundy, however, as Huntsman and Reid (1921) have pointed out. 
Approximate numbers of individuals of Sagitta elegans per square meter of sea surface, based on the 
catches of the vertical nets
