 of Cape Breton and Newfoundland. (Canadian Kec. !Sci,, vol. ii, 

 No. 4, pp. 255-258, 1886. Montreal.) 



Abstract of a paper in the Trans. Roy. Soc. of Canada. 



Matthew, George F. Synopsis of the Fauna in division 1, of the 

 St. John Group, with Preliminary Notes on the Higher Faunas of the 

 same Group. (Bull. Nat. Hist Soc. New Brunswick, No. v, pp. 25- 

 31, 1S8(), St. Joliu, New Brunswick.) 



Matthew, George F. The Structural Features of "Discina Acadica" 

 (Hartt), of the St. John Group. (Can. Rec. Sci., vol. ii, No. 1, pp. 

 9-11, figure on p. 11, 1880. . Montreal.) 



Gives some descriptive notes and a figure of a young specimen of Stenotheca 

 acadica. 



Matthew, George F. Discovery of a Pteraspidian fish in the Silu- 

 rian rocks of New Brunswick. (Canad. Rec. Sci., vol. ii, No. 4, pp. 

 251, 252, fig. p. 252, 1886. Montreal.) 



Describes the fossil fish found on the southern slope of the Nerepis Hills, in 

 King's County, New Brunswick, from beds equivalent to the Lower Helder-

Matthew, George F. Pteropod of the St. John Group. (From a let- 

 ter by Mr. G. F. Matthew, dated St. John, New Brunswick, December

States that there is no relation between Diplotheca and Phragmofheca of Bar-

 which distinguish it from other Hyolithoid shells. 



Matthew, George F. Note on the occurrence of Oleuellus ? Kjerulfi 

 in America. (Amer. Jour. Sci., 3d ser., vol. xxxt, pp. 472, 473, June,

Notes the occurrence of the fossil named in New Brunswick in the basin of the 

 Keunebecasis River, where it is associated with a number of species found 

 in the St. John basin in the bands c and d of Division i. The species are 

 similar and in some cases identical with those of the Menevian Groups of 

 Wales. 



In Newfoundland 0. (?) Kjerulji occurs in association with Agraulox nfrenuus, 

 HyohtheH Micmac, etc. 



Mr. Matthews considers it doubtful whether it belongs to OloieUn*, and says that 

 among Paradoxidw it is more closely allied to /'. Jcaduus Xhnu ;ii v other.
