LEPIDOPHLOIOS, AND ON THE BRITISH SPECIES OF THE GENUS. 557 



still one cannot resist the conclusion that, as in Lepidophloios Scoticus, so in Lepi- 

 dophloios laricinus, the cushions become deflexed, and their true apex becomes directed 

 downwards. 



The leaf-cushions, in all the species, increase in size with the growth of the stem, 

 and hence the relative proportions of their width to their length varies with the varying 

 age of the plant. 



Probably the cones of Lepidophloios laricinus were stalked, but absolute proof is 

 wanting on this point, though the example figured by Goldenberg on his pi. xvi. seems 

 to represent the fruiting condition (Halonia) of the species with the cone-stems still 

 attached. 



The Sigillaria Menardi given by Goldenberg on his pi. vii. fig. 1, has a great 

 resemblance to Lepidophloios laricinus, but when one takes into consideration the 

 enlarged figure 1b, it certainly cannot be the latter plant, though it is difficult to under- 

 stand how this fig. 1b could be derived from fig. 1. Possibly only a portion of the 

 specimen is given at fig. 1, and fig. 1b may be taken from a part not shown in the 

 portion figured. 



Lepidophloios dilatatus, Lesquereux, as far as fig. 2 * is concerned, does not appear to 

 differ in any essential character from Lepidophloios laricinus. There do not seem to be 

 any reasons given why the figs. 1, 3, and 4 of the same plate are placed under the same 

 name as fig. 2, from which they appear to differ. It is, in fact, difficult to understand 

 on what grounds such specimens as fig. 1 could be referred to Lepidophloios as its cone. 

 Such relationship appears to me to be purely conjectural. 



I believe that the specimen figured by Weiss as Lepidophloios laricinus t is my 

 Lepidophloios Scoticus. The figure is scarcely enough to determine the point, but it has 

 all the characters of this species, and originates from the same horizon. 



Lepidophloios laricinus is very rare in Britain, and hitherto I have only seen it in 

 the Middle Coal Measures.
