LEPIDOPHLOIOS, AND ON THE BRITISH SPECIES OF THE GENUS. 



.551 



specimen of Lepidophloios Scoticus. At the points where the stalked cones were 

 attached, the leaf-cushions are bent back, and form a rosette of scales, at the centre of 

 which is seen the point of attachment of the branch. Similar "rosettes" are seen 

 on PI. II. fig. 6. 



Dr Macfarlane shows a cone of this species attached to its stem, but the base of the 

 stem is broken off."* The basal portion of a similar cone-stem is shown, natural size, 

 on my PI. II. fig. 7, where it is seen to terminate in a funnel-like expansion which 

 fitted into the "rosette" on the parent stem. When in life, these "rosettes" would 

 not be so flat as shown on the fossils — always more or less compressed — but would 

 form shallow cup-like depressions, caused by the upward rising of the leaf-cushions, 

 into which would fit the base of the stem shown at fig. 7. 



Associated with these specimens from the Midlothian Oil Shales, the ordinary Halonial 

 condition is found, and one is shown in the accompanying woodcut, about half natural size. 



Lepidophloios Scoticus, Kidston. Halonial condition. From Straiton, near Edinburgh. About half natural size. 



This example shows a portion of a stem (a) which dichotomises, but from the stronger 

 growth of the left fork (b) the right fork (&') is thrown to the side ; the left fork (6) 

 again dichotomises, and the left fork (c) is thrown to the side ; this fork (c) again divides,
