Vol. 65.] ANATOMY OP LEPIDOPHLOIOS LABICINUS. 441 



Footprint A 8, spec, nov., has five toes in the pes connected by a 

 web. The manus is also five-toed, bnt corresponds to some extent 

 to I, Beasley. There is a well-marked tail- streak in the track. 



E, Beasley, which is very similar to I, really has five digits, the 

 fifth being directed backwards and only just touching the ground. 



A very small footprint is described as A 9. 



It is suggested that some of these prints may quite well belong 

 to such Thecodonts as Ornithosuchus. 



25. On the Anatomy of Lepidophloios laricinus, Sternb. By 

 D. M. S. Watson, B.Sc. (Communicated by Prof. W. Boyd 

 Dawkins, D.Sc, F.H.S., F.S.A., F.G.S. Read June 16th, 

 1909.) 



[Abstract.] 



A specimen of Lepidophloios laricinus, found in one of the coal- 

 balls of Lancashire, shows the internal structure. The species is 

 new, and is of the ordinary lepidodendroid type, but is remarkable 

 for the great size and strength of the corona and the leaf-traces. 



Lepidophloios acadianus, Dawson, which is identical with 

 L. laricinus, appears to differ in its internal structure, in having 

 still stronger protoxylein-points and leaf-traces. 



Lematophloios crassicaule, Corda, which is L. acerosus, L. & H., 

 appears to resemble greatly the Lancashire specimen of L. laricinus 

 in its structure, and is quite distinct from the specimen of the same 

 form described by Cash & Lomax. 



Lepidodendron fuliginosum, Will., a structural species, appears 

 to include a specimen the external structure of which corresponds 

 with Lepidophloios acerosus, Lepidodendron obovatum, L. aculeatum, 

 and Sigillaria discophora. 



Under these circumstances, it is proposed to take no account of 

 the impression-species in considering the synonymy of the struc- 

 tural specimens, and vice versa. When the exterior of a structural 

 specimen is actually known, it may be referred to by the name of 

 the structural species, with that of the impression-species added in 

 brackets.
