Group, the Knoxville, the Kootenay, and Lakota. It appears to be repre- 
sented in the Kome beds of Greenland, and it is common in both the 
Kootenay and Lower Blairmore of Alberta, where it is frequently repre- 
sented by characteristic fruiting specimens. In the absence of the latter 
the sterile fronds frequently vary in the direction of the associated and 
equally protean species Onychiopsis goepperti , and it is not always possible 
to differentiate between the two with any precision. 
Occurrence. Kootenay; localities CK1, CLI (in fruit), CM1, CN1, COl, 
C03, CQ4 (in fruit), CP2, DG2, and DH2. Lower Blairmore; 
localities CH5, CH6, CB1, and DA3. 
Onychiopsis goepperti (Schenk) Berry 1 
Although not known for so long a period this species has shared the 
taxonomic career of the preceding species, and like it includes a large 
number of the forty supposed species of Thyrsopteris proposed by the late 
Professor Fontaine. This species was also based on large fern fronds and 
many students consider it identical with the preceding. The two are 
certainly closely related and it is doubtful if they can be consistently 
differentiated. Most of the Alberta material I have referred to Ony- 
chiopsis psilotoides , and it would do but little violence to the facts if all 
of this material was lumped under one or the other of these nominal species. 
The geologic and geographic range is essentially the same as that of 
the preceding. To it I have referred material from three localities in the 
Lower Blairmore, all of the somewhat similar material from the Kootenay 
of this region being referred to Onychiopsis psilotoides. 
Occurrence: Lower Blairmore; localities CH2, CH6, and CS2.

Character of the fronds unknown, as are also the fructifications. 
The supposed fronds, which might perhaps be considered to represent 
detached pinnse, are narrowly linear, with a relatively strong midvein, and 
numerous close set, once dichotomous lateral veins at right angles to the 
midvein. 
This species was evidently one of the most abundant types of the 
Kootenay flora, to which horizon it is thus far confined. It has probably 
frequently been overlooked or misidentified in collections of plants of this
