Baker's elaborate monograph of the LymnmdcE of North America (No. 

 6) brings the subject down to 191 1. 



Simpsonia having been used by Rochebrime in 1904 for a group of 

 Naiades, Baker (7, p. 120) has substituted Pseudogalba for his Lymnreid 

 group. The synonymy will be as follows : 



Simpsonia Baker, Chi. Acad. Sci., Sp. Pub. 3, 191 1, p. 236. Non 



Rochebrune, 1904. 



Pseudogalba Baker, Naut. XXVI, 1913, p. 120. 



For a proposed revision of Baker's arrangement and key. see Colton 

 (22, p. 116 and 23, p. 119) and reply by Baker (8, p. 20). 



For the author's arrangement, see ante p. 6. 



LymN/Ea apicina Lea. 



Although Lea's name solida for this species has page precedence as 

 stated by Hannibal (53, p. 146), and has been preferred by Haldeman, 

 Tryon and Binney, according to Kuster (Con. Cab., Lymnaeus, p. 48) solida 

 Phil, has priority and Lea's species must be known by the later name. 



LYMNiiiA AURICULARIA (L.). 



This species seems to have become thoroughly acclimated and is extend- 

 ing its range in this country very rapidly. In addition to the localities cited 

 by Baker (6, p. 182), it has been listed from Toledo, O., by Goodrch (47, 

 p. 11) ; Lake Erie, Kingsville, Ont, by Allen (i, p. 60) ; Philadelphia, Pa.,
