440 THE CANADIAN NATURALIST. [Vol. ix. 



mit the arrangement of meetings more than a year in advance. 

 It was considered, however, as virtually pledging the American 

 Association to accept the invitation, provided it be renewed at 

 the meeting to be held in Cincinnati next year. The Committee 

 ask that it be continued, with power to add to its numbers, and 

 be authorized to correspond with men of science, abroad or other- 

 wise, to prepare for a meeting of the Association in Montreal in 

 1882. Further, that this report be communicated to the other 

 bodies which joined in the invitation. 

 The report was unanimously adopted. 



Mr. Whiteaves, then re'ad a paper on '' Some new and re- 

 markitble fossil fishes from the Devonian rocks of the northern 

 side of the Baie des Chaleurs. " He commenced by remarking 

 that until last year a long strip of the northern side of the bay 

 had been mapped as belonging to the conglomerates of the Bona- 

 venture formation, which form the base of the Carboniferous sys- 

 tem. Last year, however, Mr. R. W. Ells, of the Geological 

 Survey, discovered a fine specimen of a fossil fish belonging to the 

 genus Pterichthi/Sj of Agassi z, in Escuminac Bay, a discovery 

 which led to a careful re-examination of the locality by Messrs. 

 R. W. Ells, T. C. Weston and A. H. Foord. From the researches 

 of these gentlemen, we now know that at this point Devonian 

 rocks crop out from under the Bonaventure conglomerates, and 

 further, that these Devonian rocks hold a rich and extremely in- 

 teresting series of fossil plants and fishes. The vegetable organ- 

 isms will be described by Principal Dawson at some future time, 

 but the fossil fishes, of which many specimens were exhibited at 

 the meeting, were shown to belong to the following genera and 

 species: — 1. Pterichthys. A fine species, supposed to be new, 

 whicli has been described in the Aui!;ust number of the American 

 Journal of Science as Pterichthys Canadensis. It is very closely 

 allied to a fossil fish found in the Old Red sandstone of Scotland 

 and Russia, and is the first species of this remarkable genus yet 

 found in America. 2. Dipl acanthus, A cluster of fin rays only, 

 of a small form, possibly referable to this genus. 3. Cheirolepis. 

 A beautifully preserved fossil fish, about a foot in length, which 

 cannot at present be distinguished from the Cheirolepis cumingim 

 of Agassiz, which was so named in honour of Lady Gordon 

 Cuming, of Altyre. 4. Phaheropleuron, nov. s^. 5. Tristicho- 

 porus, nov. sp. 6. Portion of the vertebral column of the above 

 species of Tristichoporus shewing the neural and haemal spines
