Anodon triangularis, Lea, Sp. 56, is a Margaritana. 



Sp. 115, A. ciconia, Gould, the two figures represent different 

 species, the upper one being correct. Even the comprehensive 

 locality "United States" will not cover this species, which is 

 Mexican, but scarcely a synonym of A. trapezialis, Lam., as sup- 

 posed by Dr. Lea in the new edition of his Synopsis. 



Sp. 122, A. Cumingii, Lea, is a Monocondyloea. 



Sp. 124, A. brevis, Sowb., Nov. Sp. Rio de la Plata. 



Sp. 135, A. cochlearis, Sowb., Nov. Sp. Hab — ? 



Sp. 137, A. Sohomburgianus, SoAvb., Nov. Sp. Brit. Guiana. 



Sp. 138, A. virens, Lea. Two localities are given — ^" River 

 Euphrates," which is incorrect, and " Red River. Alexandria." 

 Which Alexandria is meant is not stated, but if "Louisiana" be 

 added, the latter locality will be correct. I suspect that an 

 Egyptian habitat was intended by Sowerby. 



Sp. 140, A. Henri/ana, Lea, correct locality from Tamanlipas 

 to Tamaulipas, Mexico. 



Sp. 150, A. Pepinianus, we are informed is found in " Lake 

 Pepin, County Ohio." 



Sp. 152, A. giga7iteus, Lea. The shell previously figured 

 (sp. 18) under this name, is A trapezialis, Lam. 



I here take leave of Sowerby's Unionidae, I trust forever. 

 The series of monographs composing it certainly contain more 

 errors than any other work on Natural History that I have ever 

 seen.
