E. BlumenhacMa has been heretofore referred bj me to the o-enus 

 Conocardium, but that genus has not the two Uirge iDosterior teeth ? pos- 

 sessed by this shell. It must be closely allied to Eopteria (^ante, p. 221, 

 306, 307), but differs externally in having one extremity flat. This may 

 not be sufficient to separate the genera, and should it hereafter turn out 

 that the internal structure is the same in all the species, I beo- that the 

 Euchasma be retained for the group, and Eopteria withdrawn from science. 



In the above description I have called the flat side the posterior with 

 doubt, as the specimens are not sufficiently perfect to enable me to deter- 

 mine which is posterior or anterior. 



I may explain here, also, that this genus would have been described on 

 p. 220, only that I had then hopes of procuring better specimens, and thus 

 delayed.

GRAPTOLITID^. 



A number of species of graptolites were collected at Table Head, Bay 

 St. Paul, Pistolet Bay, and Cow Head. Most of them are identical with 

 those that occur at Point Levis, but there are a few which may be new 

 species. It would require a larger collection of more perfect specimens 

 to decide. 



Table Head. — Two species, in a bad state of preservation, were found 

 at this locality in the black bituminous slates forming the upper part of 

 Division N. One of them resembles G. jyristis. The other, of which a 

 single specimen only was collected, consists of twenty or thirty stipes.
