inicroscope it yields in beauty not even to P. exlgvM. It is even 

 smaller than that minute species, the greater diameter of my largest 

 specimen being only 1-2 mm. 



Striatura ferrea, Morse. — The only si)ecioaen I liave found was 

 obtained in the hills near the iron mines in Hall on the 16th Novem- 

 ber, 1884, when several otlier interesting discoveries were made. It is 

 a very distinct species ; but to be absolutely certain of its identity, I 

 sent the shell to Prof. Morse, to whom I am under many obligations, 

 ami he returned it as correctly determined. Like S. milium it has 

 only three volutions, but is less transparent and of a dead steel-grey 

 color. The specimen found measures 2-8 mm. in greater diameter. 



Conulus fulvus, Drop. — This little shell is very common in moist 

 stations in shady woods, and sometimes in open pastures, often occur- 

 ring in company with //. viridula. It is more globose than any helix 

 found here except 6'trobila lahyrinthica, from which it differs externally 

 in being highly ]>olished. It is subject to great variation in size, the 

 greater diameter ranging from 24 to 32 mm. and the height from 1*3 

 to 2 8 ram. Jeff"reys states that in England specimens collected in dry 

 situations are much larger than those found in wet moss, but my largest 

 shells were taken in a very wet station north of Fairy Lake. 



Gastrodontct viultidentata, Binney. — From a notice of the ti'"st ex- 

 cui'sion of the Club to the King's Mountain, published in a city news- 

 j)aper, it appears that Mr. Heron found this shell there on May 22nd, 

 1880. It seems a very rare species. Repeated and careful search for 

 it was unsuccessful until my visit to the hills north of Hull in Novem- 

 ber last, when I obtained one specimen under a log in a moist, well- 

 shaded locality. It is 2-7 mm. in greater diameter. 



Patula cdternata, Say. — This is the only ornamented species of 

 land snail indigenous to Eastern North America, II. variatis, and the 

 banded variety of //. horlen-iis, baing importations from the West 

 Indies and Europe respectively. It is the commonest of our large species, 

 frequenting the open more than others, though often found in the 

 woods, and seems capable of enduring the driest situations. In the fall 

 it assembles in particularly large numbers, but is at all times more or 

 less gregarious. In April, 1882, I observed hundreds under flat rocks 

 near the old lime kilns in Rochesterville. The marl beds east of
