THE NAUTILUS. 99 
Zonites nitidus Mill. Quite rare, a few from banks of creek, St. 
Charles River. 
Zonites arboreus Say. Plentiful, but not often in good condition. 
Zonites radiatulus Alder. Plentiful. 
Zonites binneyanus Morse. \Well-distributed, but never abundant. 
Zonites ferreus Morse. Both rare and local. 
Zonites exiguus Stimpson. Woods, Isle d’Orleans, very abundant. 
Zonites fuluus Drap. Fairly abundant. 
Zonites multidentatus Binn. Isle d’Orleans only ; rare. 
Tebennophorus caroliniensis Bose. Occasional. 
Pyramidula alternata Say. Widely distributed, but only common 
on side of cliff, Isle d’Orleans. 
Pyramidula striatella Anth. Common everywhere. 
Pyramidula asteriscus 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 débris, and sifting them during 
the winter evenings. 
Helicodiscus lineatus Say. Rather abundant under accumula- 
tions of dead leaves in damp woods. 
Acanthinula harpa Say. Exceedingly common 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 thisclearing. On mainland, traces found in two widely separated 
localities. 
Punctum pygmeum Drap. Fairly common. 
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 Abbé 
_ 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. 
Polygyra 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
