8 THE CANADIAN NATURALIST. [Yol. X. 



Orhidina, and tlie arenacous character suggests nearness to 

 Saccamm'ina. which also approaches most nearly in geological 

 time. The ridged surface is no doubt unusual in arenaceous 

 tests, but a tuberculated surface is found in some, as, for in- 

 stance, in that from the Challenger dredgings recently described 

 by Brady, under the name Thurammina papillata. The name 

 Calcisplicera would be unobjectionable, were it not for the dif- 

 ference of structure in the test of the forms referred to this 

 genus, and which on this account appear to me to be possibly 

 of different nature. In the mean time, therefore, I leave the 

 question of name as it stands at the head of this notice. 



Note, (March 14, 1881.) — In a letter just received from 

 Mr. H. B. Brady, he says that he knows of no rhizopod test 

 recent or fossil, precisely corresponding to the little Erian fossil 

 above described. He says — " the more I examine your little 

 fossil the more confident I am that it bears no relation to any 

 rhizopod type that I know." It will thus appear that he does 

 not admit its affinity to Saccammina, and that he even doubts 

 as to its rhizopodal character. 



III. New Devonian Plants from the Bay de Chaleur. 



The following notes relate to the examination of plants col- 

 lected by Mr. A. H. Foord, of the Geological Survey, at Scumi- 

 nac, opposite Dalhousie, and by Mr. Weston, of the Geological 

 Survey, near Campbellton. 



Mr. Foord's collections are from the Sandstones containing 

 Pterichtliys Ccmadensis Whiteaves, and other fossil fishes, and 

 which appear in a low anticlinal form overlaid uncouformably by 

 a great thickness of red sandstone and conglomerate of the Bon- 

 aventure Formation (Lower Carboniferous). The beds seen at 

 this place are characterised by their fauna, as. of Upper Erian 

 (Devonian) age. 



1. Archceopteris Gaspiensis, s. n. 



Barren pinnce densely leafy, with the pinnules broadly obovate 

 and somewhat truncate at the apex, decurrent by a broadish base 

 on the somewhat stout striated petiole, veins forked thrice and 

 strongly curved toward the lower edge. In luxuriant fronds the 

 pinnules are 2.5 centimetres long and 1.8 centimetre broad.
