OxYPHYLLTJM, Moovc. (Fig. 519.)— Found in 1855 near 

 Dunoon, in Argyleshire, by Mrs. East, of Blackheath, and 

 subsequently near Stirling, by Mrs. Macleod. Moderate in 

 size, pinnjE brief, very oblique from the increased size of the 

 basal anterior pinnule, the latter more distant and more 

 distinct than the remainder, which become confluent. Dentation
