Remarks. — This species is very common in the Lower and Middle Coal Measures. 

 It is plentiful in the Ayrshire Coal Field, but usually occurring in a fragmentary condi- 

 tion, it is often passed over by collectors without note. The cyclopteroid pinnules are 

 placed upon the main rachis ; a fine example showing this condition is figured by Roehl.* 

 I have seen a similar occurrence of cyclopteroid pinnules on other species of Neuropteris. 



Grand' Euryt regards Cyclopteris trichomanoides as leaves or foliar stipules of Odon- 

 topteris minor and Odontopteris Reichiana. In the Lower and Middle Coal Measures of 

 Britain, cyclopteroid pinnules, which I cannot distinguish from Cyclopteris tricho- 

 manoides, Brongt., are always associated with Neuropteris heterophylla, and in some 

 cases are extremely plentiful, and from their mode of occurrence, I have no doubt that the 

 specimens to which I refer belong to that fern. My specimens clearly do not belong to 

 any of the Odontopteris to which Grand' Eury refers them, as I have found neither of 

 these species in the beds in which the cyclopteroid pinnules and Neuropteris hetero- 

 phylla occur ; in fact, Odontopteris Reichiana is very rare in Britain, and Odontopteris 

 minor has not yet been discovered in our Coal Measures. The explanation may be that 

 several species of Odontopteris, as well as Neuropteris, may have borne cyclopteroid 

 pinnules, which, when separated from their parent stems, cannot be specifically dis- 

 tinguished.
