Dr. Parncll lias ilcscribod a second species of Corrgoniis 

 fouml in Loch Loniond, which differs from tlie first in having 

 a smaller head, yet agreeing exactly in the number of all the 

 fin-rays ; but as I learn by communication with Dr. Parnell 

 that since the publication of his paper he has obtained many 

 specimens from Loch Lomond, the characters of which are 

 intermediate in reference to the two fishes described, and 

 appear to connect them, I have not figured it as a distinct 

 species.
