I have adopted for this species the synonymy composed by Schuchert, 1 

 who has given the specific limitations of these forms more detailed study 

 than any other investigator. The material from the Yellowstone National 

 Park includes orAj four specimens, one of which is the external cast of a 

 dorsal valve, shown on PI. LXXI, fig. la: the others are three ventral 

 valves, exfoliated so as to be almost internal casts. These specimens agree 

 well with Hall's description and with Meek's 2 figures of Spirifer cuspidatus (?) 

 which are here reproduced for reference. The dorsal cast shows the peculiar 

 "textile" surface ornamentation of the genus, and the shell substance, where 

 preserved, gives evidence of being punctate. Therefore, although the char- 

 acteristic structures of foramen and beak have not been observed, reference 

 to the genus and to the species under the genus seems to be justified 



It should be noticed that one of the ventral valves above referred to 

 has every character of the specimen figured by White as Syringothyris 

 extenuatus (Wheeler's Rept. U. S. Geogr. Surv. W. 100th Merid., Vol. IV, 

 1877, p. 88, PI. V, figs. i)a-M).
