20 ROYAL SOCIETY OF CANADA 
in the Queen Charlotte Islands in 1878. The paper is published in the 
Report of Progress of the Geological Survey of Canada for 1878-79. 
Dr. Dawson took home quite a large collection of shells of about 
135 species, no fewer than 22 being additions to the list, and 2 of these 
new to science. 
The new species are :—Macoma carlottensis and Lepton rude, and the 
other additions are :—Bryophila setosa, Crenella decussata, Leda cælata 
(= acuta) Astarte undata, Cryptodon flexuosus, Lucina filosa (= acutili- 
neata) Macoma sabulosa (= lata) Bela Trevelyana, Mitromorpha filosa, 
Mangilia sculpturata, Volutella pyriformis, Chrysodomus Harfordi, Odostomia 
Sitkensis, Odostomia straminea, Caecum crebricinctum, Lamellaria Stearnsii, 
: Fenella” pupoidea, “ Fissurella” bimaculata, Tonicella marmorea and 
Chetopleura Hartwegii. 
Some of the shells noted in this paper seem to have been incorrectly 
determined. A few corrections have been made by Mr. Whiteaves him- 
self in subsequent papers as follows :— 
Moera variegata, should be M. salmonea. 
Astarte semisulcata, os A. undata. 
Leda celata, + L. acuta. 
Chlorostoma brunneum, É P. pulligo. 
Galerus contortus, ss G. fastigiatus. 
The following additional corrections, to which I think Mr. Whitea- 
ves will assent, are also needed : 
Turtonia minuta.—The shell, in the Ottawa Museum, is a large 
specimen of Tellimya tumida. 
Cylichna alba.—This is C. attonsa. 
Amphissa versicolor.—Merely a small form of A. corrugata. 
A third paper by the same author was published in the Transactions 
of this Society (vol. ili., section iv., 1886). It is an account of the 
Invertebrata obtained by Dr. Dawson, principally by dredging, off the 
northern and northwestern coasts of Vancouver Island in 1885. 
One hundred and forty-seven species of mollusca are noted, fourteen 
being new to the fauna and two, so it was thought at the time, new 
to science. 
The supposed new species are: Cadulus aberrans which still stands, 
and Leptochiton punctatus the type of which appears to be a very pale 
form of Ischnochiton retiporosus. 
The other additions to the list are : Pecten Vancouverensis (recorded 
as “ Alaskensis”), Limatula subauriculata, Yoldia thracieformis, Bela 
violacea, Cancellaria circumcincta, Admete viridula (= Couthouyi) Sipho 
(misprinted Siphon) Verkruzeni, Trophon Stuarti (recorded as orpheus)
