Journal Academy Nat. Sciences, vol. i. p. 83. 
From Dr. Yale I have received two specimens of 
a “Muraena,” which answers in all important par- 
ticulars to the “ argentea." Its general color is sil- 
very gray, darker upon its upper portion, with a clear 
satiny white abdomen. The spiracles are as long as 
the base of the pectorals. This species is taken in 
pots in October, when it leaves the ponds, and sel- 
dom at other times. At Holmes Hole, it is called 
* Neshaw eel.” 
The following description of a specimen. « of each 
species, will show their different proportions. — 
specimens were each twenty-three inches in er
