MISS G. L. ELLES AND MISS I. L. SLATER OK THE [May I 906, 



the articulate brachiopoda, so characteristic of the lower beds, have 

 almost disappeared, Lingulce and the molluscan fauna alone remain- 

 ing ; and we therefore consider that the dividing -line between the 

 Upper Ludlow and Temeside Groups is best drawn at this horizon. 



The Platyschisma-Bed (E b) is practically composed of Platyschisma 

 helicites and Modiolopsis complanata. Beyrichia is also abundant 

 at its upper and lower limits. This bed gives place upward to the 



typical massive, yellow, mica-

 of the Downton-Castle Sand- 

 stones. 



The higher members of the 

 Downton-Castle Sandstones are 

 not well seen in this Teme 

 section, for, with the exception 

 of the lower beds just described, 

 which are exposed at the lower 

 end of Ludford Lane and in the 

 adjoining Leominster Road, the 

 ground occupied by them is 

 largely built over. They appear 

 to have been worked in an old 

 quarry, in the copse east of 

 Ludford Church, but this is 

 now quite overgrown. 



The lowest members of the 

 Temeside Shales (F) visible are 

 seen in two exposures in the 

 river-bank opposite the Gas- 

 works ; and, from analogy with 

 other sections, we are of opinion 

 that these are the beds which 

 immediately succeed the highest 

 beds of the Downton-Castle 

 Sandstones. They consist of 

 rubbly shales (seen at water- 

 level) overlain by massive 

 greenish micaceous sandstones 

 with Lingula cornea, and with 

 rubbly marls above again (F a). 

 For some 250 yards below this the section is interrupted, and no 

 exposures are visible. The section is, however, continued west of 

 the Sewage-works footbridge, where the higher members of the 

 group are extremely-well shown (cf. vertical section, fig. 2). 



The rubbly grey and red beds (F a), the lowest beds observed at 

 this point, appear to correspond very closely in general characters 

 with those seen opposite the Gasworks ; 12 feet of these are seen in 

 this lower exposure : they are probably, therefore, of considerable 

 thickness, although there is no direct evidence on this point. The
