The punctations or dots described and figured by Lesqiiereux ^ as 

 occurring on the pinnules of Pseudopecopteris anceps Lx. have been corre- 

 lated by Kidston and Meschinelli with the Excipula CalUpteridis found by 

 Schimper on the pinnules of Callipteris conferta. These minute fossils are 

 obscurely noticeable in portions of a specimen of Pseudopecopteris squamosa 

 (Lx.), PI. IX, Fig. 4 {Pseudopecopteris cmceps Lx.), from Missouri, though 

 they are not so cleai-ly presented as is often the case in the material from 

 Cannelton, Pennsylvania, where they appear as clearly interneural minute 

 pustules situated within the lamina, and giving to the unaided eye the 

 impression of very small dots scattered over the pinnule. 



As Kidston remarks,^ it is a matter of interest that this species should 

 be found in both Europe and America on the same host, Sphenopteris neu- 

 ropieroides Boulay, on which Excipulites Gallipterklis has been found by 

 Kidston and Zeiller,^ being recognized by those authors as identical with 

 Pseudopecopteris anceps Lx.
