" Stimpson (Marine Invertebrata of Grand Manan, p. 58) reports this 

 species (with an 1) as " very abundant in the waters of the Bay of Fundy, 

 swimming near the surface in swarms." " I have never seen specimens from 

 the Bay of Fundy, and, during several seasons spent there, I have never 

 observed any species of Mysis swimming at the surface, as described by 

 Stimpson. Thysanopoda Norvegica and inermis, however, were found in 

 vast numbers in precisely the same way as the Mysis is said by Stimpson to 

 occur, and it is possible that Stimpson, without making a special examination, 

 mistook the vast swarms of Thysanopoda for Mysis ocidata " (S. I. Smith, 

 1879; op. cit., p. 106).
