yd. 4, p. 101, in which Bothriolejns Canadensis (Whiteavea), Jcanthodes 

 Miichelli f (Egerton), Acanthodes concinnus (Whiteaves), and Fhanero- 

 pleuron curium (Whiteares) are described, either for the first time or 

 more in full than in the original papers "which announced the important 

 discovery of fishes in rocks of Devonian age, in part the equivalents of the 

 Old Red Sandstone of Scotland, from which Hugh Miller's celebrated 

 •collections were obtained, and which the famous Louis Agassiz described 

 in his " Poissons Fossiles du Vieux Gres Rouge." 



In the last volume of the Transactions of the Royal Society of 

 "Canada, Mr. Whiteaves describes the remaining species of Upper and 

 Lower Devonian fish -remains which had been collected by Mr. Foord, 

 Dr. Ells, and other officers of the Geological Survey Staff, in the Bale 

 des Chaleurs region. The paper contains descriptions and illustrations 

 of five species "from the Upper Devonian Rocks of Scaumenac Bay, 

 P. Q.," together with a note on Bothriolepis Canadensis (Whiteaves), 

 besides '' Descriptions of Species from the Lower Devonian Rocks of 

 Campbellton, N. B.," which include descriptions and figures of four 

 species. 



In the first part of the paper the following forms are described : — 

 Glyptolepis Quebecensis, N. sp., Eusthenopteron Foordi (Whiteaves), 

 Cheirolepis Canadensis (Whiteaves), Bothriolepis Canadensis (Whit- 

 eaves, note), Acanthodes affinis, N. sp., Phaneropleuron curtum (Whit- 

 eaves). 



Each species receives its full share of careful examination ; details 

 of description are given so that any observer may easily recognise the 

 species in question. Of Eusthenopteron Foordi a very exhaustive diag- 

 nosis is furnished, in which quite an array of new facts are recorded for 

 the first time. 



The second part of this paper includes descriptions of the following 

 forms : — Cejyhalaspis Gamphelltonensis (Whiteaves), Coccosteus Acadicus 

 (Whiteaves), Ctenacanthus latispinosus (Whiteaves), Homocanthzis 

 _gracilis, N. sp. They occur associated with intrusive rocks occurring 

 ■at the base of the Devonian of that region. 



Most of the illustrations were drawn by Mr. Lawrence M. Lambe, 

 artist to the survey, who also helped in a study of the several forms 

 under consideration. These two parts (Parts I and IT) of " Illustrations
