{^Supplementary Notes to a Paper read before the Association, October 8th, 1882.1 



Since I read a paper on the above subject I paid sundry visits 

 to places in this neighborhood where these organic remains were 

 originally obtained, and although not successful in obtaining 

 others in better preservation than the ones submitted for ex- 

 amination by the members of our Association, I have a few 

 more which may prove of some little interest to the Section. 



From the lower portion of the Clinton beds, above the grey 

 band, I secured fragments of the cord-like fucoid, possessing a 

 striated appearance. This may be allied to, if not identical with, a 

 form appearing in the Medina series. The plant in the latter, it is 

 true, does not usually present the longitudinal lines or fluted aspect; 

 however, in rare instances, I have remarked this peculiarity. The 

 fucoid from the Niagara sbale came from the quarry near Mr. 

 Colbeck's. It seems very well marked ; however, it may be only 

 the detached branch or branches of a Buthotrephis. Its plant 

 nature can hardly be questioned. 



The small Clinton Licrophycus here produced does not come 

 under the head L. Minor. The stem was more flexible and the tuft 

 of branches more closely bunched at an acute angle. The plant at 

 first sight would lead one to suppose it was of a soft succulent 

 nature ; this supposition may prove erroneous. Both stem and 

 branches stand out boldly in relief on the surface of the flag, though 

 difficult to reconcile with what I asserted as regards its flexibility. 

 Altogether I think there are three small species or varieties rep- 

 resented in the Clinton beds, and one in the Medina grey band. 

 In a specimen from the former, the main stem throws out a compact 

 tuft, is continued and forms a second one higher up. It appears 

 quite impossible that anything but a plant could have left this 

 impression.
