96 • Natural History of the 



soms of the Easpberry, (Rubus strigosus) near Bevin's Lake, 

 Montcalm, at tlie beginning of July. 



TORTRICINA. 



Tortrix. On the 19tli July, five miles up the Devil's Eiver, I 

 found a mass of web, spun by larvae, over the leaves and branches 

 of the Indian Hemp (^Apocyniim cannahinum') , which was 

 full of pupge of a Tortrix, and at the end of the month, those I 

 collected, produced the perfect insect, but I have been unable to 

 determine either this or any other of my 3Eero-Lepidoj)tera. 



MOLLUSOA. 



Some of the Terrestrial Gasteropoda, enumerated below, were deter- 

 mined by W. G. Binney,Esq., of Burlington, New Jersey, and a portion 

 of the Fresh Water species, and the Naiades, by Dr. Isaac Lea, of Phila- 

 delphia. It is not a little remarkable that Unio radiatus, which, as I am 

 informed by Messrs Billings and Bell, is very abundant in the Ottawa 

 at L'Original, and at the mouth of the Rouge, is not found higher up the 

 latter river. Shells of the genera LimncBa, Physa and Planorbis, were 

 remarkably scarce in every lake except Sugar-bush Lake, Montcalm, and 

 a small lake one mile west of the Indian Village on the Rouge in the 

 Township of Arundel, and in fact ;it was only in places where the 

 water was shallow and the bottom soft that they occurred at all. The 

 valves of the Unio and AnodontcB were very much eroded in most of 



the lakes. 



G-ASTEROPOD A. ( Terrestria I.) 



1. Tebennopkorus caroliniensis, Bosc. (Great grey Slug) — Common 



under bark of decaying logs, &c., throughout the 

 district. 



2. Succinea obliqua, Say. — Abundant under decaying logs on grass- 



land at Hamilton's Farm, in August. It occurred 

 very sparingly on the leaves of bushes, in other 

 parts of the district. 



3. Helix albolabris, Say (White-lipped Snail). — Not very common; 



Township of Wentworth, Montcalm and Harring- 

 ton. 



4. " exoleta, Binney. — Not uncommon under dead logs in the 



Townships of Wentworth,Harrington and DeSala- 

 berry. 



5. " monodon, Rackett. (One-toothed Snail.) — Sparingly met 



with ; portage from the Indian Village to Bark 

 Lake, Arundel ; Hamilton's Farm and near the 

 Lake of Three Mountains. 



6. " concava, Say. — Abundant under dead logs ; Townships of 



Wentworth, Montcalm and Arundel. On one 

 occasion I found an individual of this species 

 devouring the animal of Achatina lubrica, having 

 made a hole through the spire of its shell
