It is not certain, in our opinion, that the fossils from the Salt Tlange, 
described and figured by Waagen, and referred to Eiu^ydesma, really belong 
to that genus. They are certainly closely allied, but both the description 
and figures indicate structures not common to typical forms of Eunjdesma . 
Trech’s suggestion that Sangumolites Etheridgei, DeKon., >S'. cnrvatus, 
De Kon., Mytilm Bigshyi, De Kon., and M. crassiventer, De Kon., may all be 
referable to Ewvjdesma, has already been referred to (p. 46). There 
appears to be no evidence in support of the suggestion.
