532 Short Communications : — 



The inaccuracy of his figure, regarding the dorsal and ventral 

 fins, might arise from the error of the engraver, as your figure 

 is not much better in that respect, originating from the same 

 cause. Your correspondent states that he possesses a spe- 

 cimen, with a description and figure, of another species of 

 Pennant's genus Leptocephalus, wanting the pectoral fin. 

 He would much benefit his favourite science by communi- 

 cating them to the scientific public through the medium of 

 your widely circulating Magazine. On turning to p. 200. of 

 Fleming's British Animals, I find that he refers to a memoir 

 of the late Colonel Montagu concerning the fish, in the Wer- 

 nerian Memoirs, vol. ii. p. 436. xxii. 1. — Henry Vietz Deere.

Molluscous Animals. — Mytilus polymorphus. This cu- 

 rious muscle, which appears to thrive equally well in salt or 

 fresh water, is said to be a native of the Danube, but may now 

 be considered as a naturalised species. It was first noticed by 

 Mr. Sowerby, who found it in the London docks : and lately 

 it has been found in vast abundance in the Clyde and Forth 

 canal, towards its eastern extremity; and thence plenty of 

 living specimens have been communicated to me by my brother, 

 Mr. A. Scouler. — John Scouler, M. D. Glasgow, Oct. 4.
