NEW SPECIEB OF LEPIDOSTHOBUS 
91 ■ 
Some of the character which are not well shown on those at- 
tached to the cone, have been taken from the detached speci- 
mens. In one of the largest and best preserved of the separate 
scales (Plate IX, fig, 4) the sporangiophore is 12 mm. long and 
9 mm. broad; the blade is 17 mm. long and 12 mm. broad, with 
the apical angle 44°. In over 50 separate specimens examined 
the apical angle ranges from 40° to 50°. 
The species most closely allied to Lepidostrobus minto ensis are 
Lepidophyllum tnangulare Zeiller, L. pichleri Kemer, L, jenney\ 
White, L. ovatifolium Lesq,, L. brevifolium Lesq., and perhaps 
Lepidostrobus ? trigonolepis Bunbury. Both Lepidophyllum tri- 
angulare and L. pichleri have not only acute apices of the blades 
but the angles at the base are sharply pointed, while the basal 
angles of the Minto specimens are slightly rounded and the 
blade is generally of a much broader type. The sporangiophores 
of the latter are slightly longer, indicating a larger cone, and they 
are generally broader, Zeiller's species, on the contrary, are 
described as characteristically narrow. The scales of Lepido- 
phyllum jenneyi seem to have shorter sporangiophores and the 
blades are slightly convex at the border and less pointed at the 
apex than the Minto specimens, and they have semiangular or 
rounded dilations or auricles at the base. Compared with the 
Minto scales Lepidophyllum haslatum is longer andmuchnarrower, 
the blades of Lepidophyllum ovatifolium, have convex 
borders and a more obtuse apical angle, while Lepidophyllum 
brevifolium have narrow sporangiophores and short blades with 
distinctly convex borders. 
C. J. F. Bunbury in 1847 described a cone from the Sydney 
coal-field of Cape Breton, N.S., under the name Lepidostrobus? 
trigonolepis , the scales of which, he says, are of a “broad tri- 
angular form, acute/ 7 which agrees in a general way with the 
Minto scales, but he adds they are slightly convex and that 
they seem to be attached to the axis by a very short claw. 
These latter characters clearly separate it from the species here 
described. Unfortunately Bunbury did not figure his specimen 
and his description is too general to admit of exact comparison. 
Lepidostrobus squamosus,\ Dawson, from Grand lake, N.B., 
was described as allied to Bunbury’s species, but larger. The 
type is in the Redpath Museum, Montreal, and through the
