Neuropterts sp. 

 PI. Ill, fig. 4; pi. IV, fig. 1; pi. V, figs. 1 and 3. 



Numerous detached eyclopterid pinnules of Neuropterts Sp. were found 

 at the Yoho School locality. As none of these pinnules were found in actual 

 connections with the parent plant their determination is uncertain. The 

 form shown in pi. V, figs. 1 and 3, bears a rather close resemblance to the 

 eyclopterid pinnules of N. Jenneyi D. W.'^ 



Detached pinnules of two other undetermined species of Pecopleris are 

 shown in plate IX, fig. 4, and pi. X, fig. 1. The former is from the Aslierville 

 locality and the latter is from Schroepferman's mine.

 Pt. II, p. 886. 

 The fragmentary forms in hand n'ljrcscnting tliis sjx'cies seem to differ 

 in no essential characteristic from the forms dcscrilx'd from Ohio except 

 that they are much smaller. 

 Locality: Yoho School. 



Alelhopleris sp. 

 Plate III, figs. 1, 2. 



Only two fragments of this form were found. It is very probable that 

 this is an undescribed si)ecies ])ut the material is insufficient for determination 

 and description. 



Locality: Yoho School.

The forms representing this species agreed closely with the forms from the 

 Pottsville region of Pennsylvania. The finely punctuate ami rugose nature 

 of the lamina is not well shown in the figure. 



Localit.y: This species was abundant at tlic ^'olio School locality.
