scales." A woodcut accompanies the description, but is 

 too coarsely drawn to illustrate anything except that 

 there is no dichotomy. 



The specimen was said to run nearly at right angles 

 to the bedding (? cleavage), and that it lay upon the 

 surface of a boulder taken from the glacial drift. 



In this case, as with previous writers, there is a lack 

 of positive evidence, but an attempt has at least been 

 made to describe the supposed fucoid intelligently. It is 

 most unfortunate that the woodcut does not increase, but 

 rather nullifies, the value of the description. 



The species cannot be accepted as a good one, nor is 

 there evidence to show that the boulder was derived from 

 the slates of the island. There is no certain knowledge 

 of plant remains. 



Animal remains are of a less uncertain character than 

 the fucoids, but are few in number and species and far 

 from satisfactory. 



We have already seen that Profs. Harkness and 

 Nicholson recorded Palceochorda ; E. W. Binney figured 

 and described Nemertites inonensis and Neretites monensis, 

 and added the Cambrian brachiopod, Lingulella davisii. 



To these must now be added a few fragments of 

 Hydrozoa, and the impression of an obscure trilobite 

 [, but they are evidently very rare as later searches have, 

 up to the present, been unsuccessful. — G. W. L.]. 



In the north quarry from which the specimens were 

 obtained, the slates are strongly cleaved and break up 

 readily into irregular shuttle-like masses. The cleavage 

 planes form an acute angle with the bedding, which is 

 frequently indicated by bands of colour. The slates are 

 much iron-stained, and in close association with grits and 

 the remarkable "crush-conglomerates" described by Mr. 

 Lamplugh.
