4. Highly interesting discovery of new Sauroid Remains.—Mr. 0. ¢. 
Marsh, a student in the Sheflield Scientific School of Yale College, pro- 
cured last summer from the Coal Formation of the Joggins in Nova 
Scotia, where he has for several seasons spent his long vacation in min- 
eralogical and Se ae observations, two Saurian vertebrae, of which 
Agassiz writes to us thus 
“ My Dear Billion, student of ho Scientific School, Mr. Marsh, 
has shown me to-day two vertebra from ‘oal Formation of the Jog- 
gins, which have excited my interest in che highest degree. I have never 
seen in the body of a vertebra such characters combined, as are here ex- 
hibited. At ie ir they might be mistaken for ordinary Ichthyosau- 
rus vertebrze ; closer examination soon shows a singular notch in 
the body of the erie itself such as 1 have never seen in Reptiles, though 
this character is common in Fishes. We have here undoubtedly a nearer

The discovery nd the Ichthyosauri was not more 
faijortiént in that of these vertebree; but what would be the knowl-
