So far as the characters of each can be made out, the dorsal valve of this shell 

 agrees vpith what maj^ be regarded as typical specimens of S. carteri., but the ven- 

 tral valve seems to be more erect than the corresponding one of that species. The 

 same is true when comparison is made with the specimen from the White Pine 

 mining region which was figured by Meek (1877, loc. cit.), but the latter is somewhat 

 distorted by crushing. Other specimens from the White Pine district show a similar 

 erect habit.
