half a raile north of the Aylraei' Road tollgate. They were large for 

 the species and of a rich amber colour. Shells of equal size but paler 

 on the body whorl and tinged with red towai'ds the apex were found 

 on the Ontario shore of the Ottawa near Mason's mill in company with 

 Succinea avara, Say, and Ilyalina nitida, Muller. 



The young of Succinea ovalis were taken on alders in the Hull 

 beaver meadow at the height of eight feet from the ground, where they" 

 were observed both by Mr. Harrington and one of the leaders of this 

 branch. This climbing habit of a species which usually lives at the 

 very edge of a pool or sti'eam is not a little remarkable. Succinea 

 avara has also been observed climbing to a height of three feet on tali 

 fronds of Struthiopteris germanica in Billings' bush. 



A succinea resembling ovalis, but smaller and more acuminate,. 

 was found in abundance on floating timber in Skead's Bay near the 

 Remices Rapids in October, 1882. Specimens collected at that time 

 were afterwards mislaid ; and on a visit to the same place in October, 

 1883, no shells of the kind could be found. This locality should be 

 visited again during the coming season and an effort made to collect 

 some of these shells. A small form of Limncea stagnalis is also found 

 there and is of much interest. 



In the report of the branch made in 1883 mention is made of the 

 occurrence in a garden in this city of a single specimen of Limax 

 agrestis, Linn. In the preceding years this slug was not observed 

 either by Mr. Hei^on or Mr. Latchfoi'd. The garden in which one 

 solitary individual was found in 1882 aflforded hundreds in 1883. Last 

 year in and around Ottawa L. agrestis was abundant everywhere, both 

 alone and in company with the smaller and common native species, Z. 

 cam2yestris, Binney. 



L. agrestis is of toreign origin, but has long been known as inhabit- 

 ing the cities along the Atlantic coast. Its migi-ation has since been 

 steadily inland ; and its advent in Ottawa is of interest not only from a 

 scientific but from an economic point ot view, as it is an exceedingly 

 prolific and voi*acious species. Gardeners have already complained of 

 its destructive attacks on lettuce, spinach and other tender esculents 

 and its continu ed increase may be regarded with some apprehension.
