1052 General Notes. [October, 
lection was some time since placed in my hands for determina- 
tion, and I have now much pleasure in submitting a list of the 
shells to the many students of science who take an interest in the 
distribution of the Mollusca. 
Land Shells: Helix hortensis Miull.; Macrocychs concava Say; 
Hyalina nitida Müll., Patula striatella Anthony; Conulus fuivus 
Drap. ; Vallonia pulchella Müll. ; Helicodiscus lineatus Say; Vitrina 
limpida Gould; Cionella sudcylindrica L.; Pupa muscorum L.; P. 
pentodon Say ; P. hoppii Möller; Vertigo gouldii Binney ; Succinea 
obliqua Say; S. ovalis Gould; S. avara Say; S. verrilli Bland. 
Fluviatile Shells: Zimneæa stagnalis L.; L. palustris Mill; R 
emarginata Say ; Physa heterostropha Say ; Bulinus hypnorum L.; 
Planorbis bicarinatus Say; P. campanulatus Say ; P. deflectus Say; 
P. parvus Say; Valvata sincera Say; Pisidium abditum Hald. ; 
Anodonta fragilis Lamarck. 
Professor Macoun was informed that a large kidney-shaped 
mussel occurred in Fox river—a locality which he was unable to 
visit. This shell no doubt is Margaritana margaritifera—alrealy 
recorded from Anticosti by Professor Alpheus Hyatt. , pine? 
nula harpa Say, was not observed, although from being foun 
on the mainland opposite, in Gaspé, and inward along the St. 
Lawrence to Montreal, its presence might be expected. Both i 
plain and banded forms of Æ. hortensis were collected, but none 
var. nemoralis. Vallonia pulchella is the strongly ribbed at 
(costata Miill.), which has not, I believe, been found crates 
anada, where the typical form is very common, but whi a 
known to occur at various points in the United States. Succi

verrilli does not seem distinguishable from S. avara, ee 
doubtful, but is probably that species. The Anodonta h Ti 
distinct from the pale, thin forms of fuviatilis which it's i e 
tom to call fragilis, and probably more nearly approac oe 
marck’s species—originally described from Newfoundlan 
ica and Europe. Of these Conulus fulvus has the most mre 
distribution north and south, while others of them— Crone e 
cylindrica, Patula striatella, Bulinus hypnorum, Limnæa st Jand. 
and L. palustris—range with it across Canada to Vancouver z 
— rank R. Latchford, Ottawa, Ont. 
GILL on THE Hanits or Fisnes—Professor Gill give Oe 
lowing notes in a late number of Forest and Stream: h found 
an interesting instance of the female of one type of ss riod- 
in South America, the Aspredinidæ, in which there occur ar are 
ical swellings of the skin of the abdomen in which the ege 
received, and therein they are nourished for some time.
