PLEISTOCENE FOSSILS. 271 



" FumcuHna quadrangularis (Pallas) = Pavonaria quadrangularis. 

 Johnston. 



" Fragments of the full-grown quadrangular calcareous skeleton- 

 rods. They are in good condition, and much more recent-looking and 

 less decayed than a similar rod which I dredged two months ago to the 

 N.E. of the 'Maiden Rock' near Oban. There can be no doubt that 

 this Oban specimen was 'recent'; for although I did not dredge it 

 living, it was close to this locality that Mr. McAndrew obtained the 

 first known British example of this species. FimicuHna quadrangular^ 

 is at present known to range from the Adriatic Sea (Kolliker) to the 

 Minch (' Porcupine' Expedition, 1869) on our own coast, and Kattegat 

 in the Scandinavian Seas (Malm)."

FOSSIL PLANTS. 



The first locality where fossil plants in any considerable 

 number were obtained, was Green's creek on the Ottawa, 

 where they owe their preservation to the nodules of cal- 

 careous matter that have enclosed delicate specimens, 

 which otherwise could not have been secured from the 

 soft Leda clay in which the nodules are enclosed. They 

 are associated with Leda arctica and with skeletons of 

 Mallotus and other fishes. In addition to specimens 

 collected by myself, I have examined the collections made 

 by the late Rev. Mr. Bell of L'Orignal, those of the late 

 Sheriff Dickson, and those of the Geological Survey. The 

 whole were described in my paper in the Canadian 

 Naturalist for February, 1866, and included nine or ten 

 species of phaenogams, a moss, and an alga. Subsequently, 

 additional specimens from this place were collected by 

 the late Mr. J. S. Miller, and by Mr. J. Stewart of
