FOSSIL SPECIES. 
M. saxorum Cockerell in Am. Mus. Nat. Hist. Bull. 24: 107. 
pl. 10, fig. 47. 1908. 
Pedicels 6.5 mm. long; calyx 18 mm. long, teeth sharply pointed, 
upper and lower teeth 6 mm. long, lateral teeth 5 mm. long. 
This is a well-preserved specimen from the Tertiary and was 
discovered in Colorado. Cockerell says that it has a calyx formed 
"approximately as in M. guitatus." In that species, however, 
the teeth are broadly rounded and the upper one is two to three 
times as long as the others. The fossil calyx seems to be more 
nearly related to Tropanthus or to Eumimulus.
