Group JOHANNOPHYTON.' 
Johannophyton (Alethopteris Dn.) discrepans, Dn.) 
Sporangites acuminata Dn. (Fruit of the above Pteridosperm. 
Alethopteris ingens, Dn. (A rare species, no type in the Natural 
History Society type collection). 
A.—Perleyi, Hartt. 
Group GINKGOPHYTON.? 
The next group is not uncommon in the Devonian as well as in the 
Little River group, and in the latter is represented by 
Ginkgophyton Leavitti. 
Cyclopteris (Aneimites) obtusa, Dn. 
C.—(Archeopteris) valida, Dn. (This species has the aspect of an 
Aneimites or Triphyllopteris, rather than of Archæopteris). 
? C.—(Aneimites) Bockshii, Gôpp. Dn. (A smaller form than 
A. obtusa but the specific reference needs revision). 
Group PSEUDOBAIERA. 
This group also has resembling species in the Devonian, viz., certain 
dissected Sphenopterids (Sphenopteridium), and has mucronate tips to 
the lobes of the pinnules like certain Archæopterids, and Ginkgophyl- 
lids. 
Pseudobaiera McIntoshv. 
? Cyclopteris (Archæopteris) Jacksoni, Dn. (I have not found this 
form in the Little River group, nor is it among the types returned by 
Sir William to the Natural History Society Museum at St. John). 
Group LyYGINOPTERIS.‘* 
Species of the type included in this group, of Coal Measure age, have 
been found to be Pteridosperms, but the connection of seed-bearing parts 
with the vegetative branches has not yet been shown for the corres- 
ponding forms of the Little River group. 
Sphenopteris marginata, Dn. 
S.—Hoeninghausi, Brongt, Dn. 
? S.—Hitchcockiana, Dn. [Said by Dawson (page 52) to be possibly 
the spore cases of an Archæopteris].
