Remarks . This variety is characterized by its robust form and short 
hinge-line. Upon comparison with Haynes’ material from Montana there 
is no doubt of the Minnewanka form belonging to this variety. The form 
described by Kindle 1 from New Mexico and illustrated by his figures 2, 
3, and 5 appears to belong to this variety, but as we have not seen his 
specimens it is not placed definitely in the synonymy. 
Locality and Horizon. Upper Devonian of New* Mexico, Colorado, 
and Montana. In the Minnewanka region in the Upper Devonian of 
sections 2-38 (lowest 55 feet) (c); 4-3 (?)-5 (c). 
Spirifer whitney i cf. gallatinensis Haynes 
1916. Spirifer whitneyi gallatinensis Haynes, Annals Carnegie Mus., vol. 
10, p. 35, Pi. 5, figs. 3-4. 
Remarks. This variety is characterized by the low, usually flat, 
cardinal area which is of equal width throughout its entire extent. The 
Minnewanka form apparently agrees with Haynes’ type, except that the 
former has a proportion ately greater breadth; Haynes gives for length of 
an average specimen 19 mm., width 29 mm., height of cardinal area 4 mm., 
width of delthyrium 4 mm. One Minnewanka specimen was noted with 
this proportion; the other extreme was noted in a mucronate individual 
having a length of 11 mm. ±, length of hinge-line of 66 mm., and height of 
cardinal area of 1 mm. This height was very slightly less at the cardinal 
extremity than at the beak. 
Locality and Horizon. Upper Devonian of Montana. In the Minne- 
wanka region in the Upper Devonian of section 2-38 (r). 
Spirifer raymondi Haynes 
1916. Spirifer raymondi Haynes, Annals Carnegie Mus., vol. 10, p. 31, 
PI. 5, figs. 1, 2, PI. 6, figs. 12, 13. 
Remarks. Our specimens agree fully with Haynes co-types with 
which they were compared. Radial surface striae w T ere observed upon some 
of his specimens. This species differs from S. pinonensis Meek 2 in that the 
latter form has length and breadth subequal (instead of 1 to 2), cardinal 
extremities rounded, 11 to 14 plications upon each side of median fold and 
sinus (instead of 8 to 12). 
Locality and Horizon. Upper Devonian of Montana. In the Minne- 
wanka region in the Upper Devonian of sections 2-38 (r); 4-5 (r).
