Catai,ogue; Rece;nti,y Described Mollusca i8i 



LampsiIvIS ANODONToiDEs (Lea). 



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

 346). It has been identified with U. teres Raf. by Say, Conrad and others. 



Lampsilis ARKANsENSis (Lea). 



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



Lampsius AMCENA (Lea). 



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



Lampsilis borealis (Gray). 



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

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



Lampsilis brlvicula (Call). 



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



Lampsilis capax (Green). 



Is a Proptera according to Coker and Snrber, (21, p. 179) and Ortmann 

 (81, p. 67). 



Lampsilis cariosa (Say). 



Unio pallescens Lea var. 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 ellipsiformis (Con.). 



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



Lampsilis eallaciosa 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 size and shape. 



Carunculina glans (Lea). 



Unio castus minis De Gregorio, Moll, di aq. dul. di Amer., 1914, p. 22. 



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

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

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

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