systems. In the St. Lawrence and Mississippi systems the species 

 is generally distributed, but in the Eastern system it is confined 

 to the neighborhood of the boundary between the Eastern and 

 St. Lawrence systems, in Central New York. The species seems to 

 have come into the Eastern s} T stem quite recently, and has been, 

 and perhaps is yet, of rare occurrence. Our collection contains 

 one specimen from Mohawk, Herkimer county ; Prof. E. E. Call 

 reports two specimens from the same place, and Mr. Charles T. 

 Simpson reports one specimen in the National collection from the 

 same place and sends me the following note : "No. 85435 is a 

 shell sent by Dr. James Lewis from Mohawk, N. Y., and in a 

 note Dr. Lewis says 'The only living specimen I ever found here,' 

 and he has labeled it U. luteolus, Lam. Lea has done the same 

 thing, and yet T should pronounce it rather an inflated female 

 U. radiatus. It is luteolus in everything but the epidermis, which 

 has that peculiar greenish tint and is roughened after the manner 

 of radiatus." 



Mr. Simpson has also given me the following note concerning 

 a specimen from Cohoes Falls : " Specimen No. 85437 in the 

 Isaac Lea "collection is labeled 'Unio luteolus, Lam., Cohoes 

 Falls, Hudson River.' The name is in Dr. Lea's writing, but I 

 think the locality is marked by some one else. In the record no 

 statement is made as to who collected it or of whom he received 

 it, but Dr. Lea evidently believed it to be from that locality." 



Mr. Albert Bailey (Nautilus Y, 2 5) reports that he found the 

 species between Ilion and Utica, and collected 27 specimens in
