Lampsilis ANODONToiDES (Lea). 



This species belongs to Lampsilis s. s. according to Ortmann (79, p.

This species is a Micromya according to Ortmann (81, p. 54). 



Lampsius amgena (^ea). 



Is a synonym of L. nebiilosa (Con.) according to Ortmann (81, p. 64). 



Lampsieis boreal is (Gray). 



The citation of this species from Oneida Lake by Baker, (9, p. 257) 

 has proved to be erorneous. See Baker, (10, p. 75). 



Lampsilis brevicula (Call). 



Is a Micromya according to Utterback (135, p. 434).

Unio pallesccns Lea van De Gregorio, Moll, di aq. dul. di Amer., p. 9, non 

 Lea, 1845. 



Lampsilis constricta (Con). 



Is a Micromya according to Ortmann (81, p. 66). 



Lampsilis ellipsieormis (Con.). 



Is a Nephronaias according to Utterback (135, p. 341). 



Lampsilis fallaciosa Smith. 



Is a Lampsilis s. s. and doubtfully distinct from L. anodontoides ac- 

 cording to Ortmann (79, p. 347). But Surber (127, p. 5) states that the 

 glochidia of the two species differ both in siz.e and shape. 



Carunculina glans (Lea). 



Unio castiis minis De Gregorio, AIoll. di aq. dul. di Amer., 1914, p. 27. 



Frierson (42, p. 7) has identified Unio (Toxoclasma) lizidus Raf. as 

 this species. If identifiable, and it is not at all certain that it might not be 

 the piillits of Lea, it would have priority. If it can not be definitely deter- 

 mined what species it is, it should be rejected for indefiniteness.
