in the Queen Charlotte Islands in 1878. The paper is publislied in the 

 Keport of Progress of the Gl-eological 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, Crendla decussata, Leda ccelata 

 ( = acuta) Astarte undata, Cryptodon Jlexuosus, Lucina filosa ( =: acutili- 

 neata) Macoma sabulosa (= lata) Bela Trevelyana, Mitromorpha filosa^ 

 Mangilia sculpturata, Volutella pyriformis, Chrysodomiis Harfordi, Odostomia 

 Sitkensis, Odostomia straminea, Coecum crebricinctum, Lamellaria Stearnsii, 

 " Fenella " pupoidea, '' Fissurella " bimaculata. Tonicella marmorea and 

 Chcetopleura Hartwegii. 



Some of the shells noted in this paper seem to have been incorrectly 

 determined. A few corrections have been made b}^ Xr. Whiteaves him- 

 self in subsequent papers as follows: — 



Moera variegata, should be M. salmonea. 



Astarte semisulcata. " A. undata. 



Leda ca'lata, " i. acuta. 



Chlorostoma brunneum., " P. pulligo. 



Galerus contortus, " G. fastigiatus. 



The following additional cori"ections, to which T think Mr. Whitea- 

 ves will assent, are also needed : 



Turtonia minuta. — The shell, in the Ottawa Xuseum, 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. iii., section iv., 1886). It is an account of the 

 Invertebrata obtained by Dr. Dawson, principallj" by dredging, off the 

 northern and northwestern coasts of Vancouver Island in 1885. 



One hundred and forty-seven species of raollusca are noted, fourteen 

 being new to the fauna and two. so it was thought at the time, new 

 to science. 



The su Imposed new s]iecies 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 : Pecien Vancouverensis (recorded 

 as " Alaskensis "), Limatula subauriculata, Yoldia thraciceformis, Bela 

 violacea, Cancellaria circumcincta, Admete viridula (= Couthouyi) Sipho 

 (misprinted Siphon) Verkruzeni, Trophon Stuarti (recorded as orpheus)
