THE NAUTILUS. 99 



Zonites nitidus Mull. Quite rare, a few from banks of creek, St. 

 Charles River. 



Zunites arboreus Say. Plentiful, but not often in good condition. 



Zonites radiatufiis Aider. Plentiful. 



Zonites binneyanus Morse. Well-distributed, but never abundant. 



Zonites f err eus Morse. Both rare and local. 



Zonites exiguus Stimpson. Woods, Isle d'Orleans, very abundant. 

 . Zonites fulvus Drap. Fairly abundant. 



Zonites multidentatus Binn. Isle d'Orleans only ; rare. 



Tebennophorus earolinlensis Bosc. Occasional. 



J'l/ramidula alternata Say. Widely distributed, but only common 

 on side of cliff, Isle d'Orleans. 



Pyramidula striatella Anth. Common everywhere. 



Pi/ramidula asteriscns Morse. Plentiful in a piece of swampy 

 wood, Isle d'Orleans, area of distribution very limited, and no trace 

 elsewhere in district. I got a good supply of these shells by taking 

 home a quantity of dead leaves and debris, and sifting them during 

 the winter evenings. 



Helieodiseus lineatus Say. Rather abundant under accumula- 

 tions of dead leaves in damp woods. 



Acanthinula harpa Say. Exceedingly commou in a small, rather 

 dry clearing (covered with a little low bush and bracken) between 

 woods, Isle d'Orleans. Eearly one morning, after a very damp 

 night, Mr. Latchford took a number off the trunks of the small trees 

 in this clearing. On mainland, traces found in two widely separated 

 localities. 



Punctum pygmceum Drap. Fairly commou. 



Helix rufescens Penn. Very abundant throughout the city, espe- 

 cially on the cliffs and city walls. Extends along the cliff some dis- 

 tance up the St. Lawrence ; a large colony noticed at St. Sauveur ; 

 a few up River St. Charles, and a small colony on the Isle d'Orleans, 

 close to the ferry landing. Recorded from Levis by the Abbe 

 Begin. This species appears to be spreading rapidly. 



Helix cantiana Mont. Common on cliff bordering Plains of 

 Abraham and extending to the citadel. Not noticed in the city. 



Polygyra albolabris Say. Well distributed, but not common. 



Po/ygt/ra albolabris var. maritima Pils. Some half-dozen exam- 

 ples, apparently this variety, taken here. 



Helix dentifera Binn. Local, but where found at all, more plenti- 

 ful than albolabris or sayii. At St. Romauld's a small colony was
