 are characteristic of beds in which iStringooephalus has actually been 

 found. It has been omitted in some few instances, such as in the case cif 

 Cyrtimi /fmni/tOQir/iiKisj for example, where the species seems to Ije rare in 

 the Stringocephalus zone, but abundant in the beds below or aljove that 

 zone ; and it is of course not prefixed to species from beds whcse litho-

 his Monogi-aph on the fossils of the Devonian Ro(-ks of the South of Eng-
