On the Buenos-Ayres Finner. By Dr. BURMEISTER. 
(In a letter to Dr. J. E. Gray.) 
I have received another Whale, well preserved and entire, of 
which I have made a careful drawing, which I intend to publish as 
soon as the skeleton is cleaned and transported to the Museum. At 
present I am not quite certain of the identity of the animal; but I 
believe it is Physalus patachonicus. The body is sixty feet long, six 
feet high, and sixteen feet in circumference ; it is a 
plete specimen which I described three years ago was a female, so 
that now I shall have both sexes of the species. Unfartaustély 
and I a i 
any thing of the intestines. As the body is deposited on the shores 
of the river nearly two miles from Buenos Ayres, it is somewhat 
difficult for me to study it in detail; so that I shall only be able to 
present to the scientific public a drawing of the entire animal and 
its skeleton, which I shall send to you, to have published in London. 
New Localities for Zonites glaber. 
To the Editors of the Annals and Magazine of Natural History. 
GENTLEMEN, 
In your May number of the * Annals, Mr. Jeffreys describes a 
new British land-shell, Mens glaber. Tt may be interesting to 
many of your readers to a few other localities whence I have 
obtained it:—In 1862 Rea near Leeds ; in 1864 my son took it 
in Guernsey ; in 1868 I took it at Bristol ; same year near London ; 
in 1869 from Jersey. 
I remain, Gentlemen, 
Yours, &c.
