EOPHY'ON JUKESI Billings. 
Eophyton jukesi Billings, 1874. Geol. Nat. Hist. Survey Canada; Pal. Fossils, Vol. II, 
Part I, p. 66, 
Professor Billings doubtfully identifies EL. linne@anum, and describes 
E. jukesi as a new species, on account of the greater size of the stems. 
EOPHYTON (?) EXPLANATUM Hicks. 
Eophyton (?) explanatum Hicks, 1869. Geol. Mag., Vol. VI, p. 535, Pl. XX, fig. 1. 
Dr. Hicks referred this species, with doubt, to Eophyton, and it has 
since (according to Dr. Nathorst) been referred to the sponges.! 
EOPHYTON (?) PALMATUM Nicholson. 
Eophyton (?) palmatum Nicholson, 1869. Geol. Mag., Vol. VI, p. 497, Pl. X VIII, fig. C. 
It is doubtful whether this form should be referred to Kophyton. It 
occurs in the Skiddaw slates (Ordovician).
