108 BERENICE A. 



(Reuss), 1 which has the same large, flat, discoid zoaria, serial, 

 crowded, and slightly reflexed peristomes. This form resembles 

 J3. scolinula so closely that it cannot be regarded at most as 

 more than a variety ; but I do not include it definitely among the 

 synonyms without having seen a specimen. It is described by 

 Reuss as rare.
