occurrence in Sodus Bay it is assumed that it will eventually be 

 found in bodies of water between Michigan and New York, and from 

 the fact that Sodus Bay is connected with Lake Ontario it might be 

 expected in that lake. The New York specimens correspond in every 

 detail with those found in Michigan. 



EURYTEMORA AFFINIS Poppe. 



This species is found very abundanth'^ in many places on the coast 

 of Europe, in salt, brackish, and fresh waters. It was fu-st reported 

 in America by Herrick,' who says that it lives in the shallow bays and 

 estuaries along the Gulf of Mexico. Foster,^ 1904, gives definite 

 localities near New Orleans, and Pearse,^ 1906, records its occurrence 

 on Nantucket Island, Massachusetts. Therefore its occurrence in 

 great numbers, in the museum collections from the St. Johns River 

 and Little Lake George, is no more than would be expected. Its 

 occurrence in Flat Lake, Louisiana, and Black Bayou, Mississippi, 

 however, is of a good deal of interest. Flat Lake is about 40 miles 

 from the Gulf, while Black Bayou is more than 200 miles from the 

 Gulf, and has an elevation of 144 feet. Inasmuch as Eurytemora 

 afflnis is commonl}' considered a salt-water form which is capable, 

 after migration, of continuing its existence in brackish or fresh water, 

 it is rather surprising to find it at a place so remote from salt water as 

 Black Bayou. 



It may be noted, in tliis connection, that Nordqvist * states that 

 Eurytemora lacustris is found in lakes from 207 to 252 metere above 

 the sea.
