334 Mighey Catalogue of 



Genus Pupa. Lam. 



P. contracta, Say. Through Mr. Blake, I have received a 

 few specimens of this from Bangor. 



P. modesta, Say. I have found a very few specimens of 

 this species near the Cape Cottage at Cape Ehzabeth. It has 

 also been detected in the interior of the State. 



P. curvidens, Gould, (pentodon, Say.) Found with P. con- 

 tracta, at Bangor. 



P. exigna, Say. Mr. True has found a few specimens at 

 Monmouth. Through him 1 have also received several speci- 

 mens of a Pupa which appear to me to accord perfectly with 

 Say's description of his P. ovata. 



Genus Bulimus. Brug. 



B. luhricus, Muller. Brug. Mr. True has detected this 

 species at Monmouth, and I have found it under damp leaves 

 at Cape Elizabeth, near the sea. 



Genus Succinea. Drap. 



*S'. campesiris, Say. Gould. Adams. I have found this 

 species most abundant in forests, under heaps of damp leaves ; 

 it is, however, frequently found in cultivated fields. I once 

 found it in plenty on a dry clay bank, larger than common, and 

 with a remarkable obliquity of the spire, which, I presume, 

 may be Say's S. obliqua. It probably inhabits all the States 

 in the Union ; and if Dr. Gould is right in his surmise, that it 

 is identical with S. amphibia, Lam. of Europe, (of which, 

 however, I am* more than doubtful,) it surely has a wide 

 range 1 



*S^. avara, Say. Found by Mr. True, at Monmouth. 



S. ovalis. Say. I have often found this species on the 

 margins of ponds, adhering to the stocks of aquatic plants 

 and bits of floating wood, just at the edge of the water, where 

 the surface is always wet.
