Anodo7i triafigularis, Lea, Sp. 56, is a 3Iargaritana. 



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 ^. trapezialis, Lam., as sup- 

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



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



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



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



Sp. 137, A. Sohomhurgianus, Sowb., 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. Ileurgana, 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. giganteus, 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.
