Note on the Tetrapedos Smithii of Jan. 
By Dr. J. E. Gray, F.R.S., V.P.Z.S., &e. 
In a recent Number of the ‘ Archiv fiir Naturgeschichte’ (vol. xxv. 
p- 69, t. 2), a reptile from Ceylon is described by Prof. Jan of Milan, 
under the name of Tetrapedos Smithii: it is the same as Evesia 
monodactyla, described by me in the ‘ Annals of Natural History,’ 
ser. 1. vol. ii. p. 336, in 1839, and in the ‘ Catalogue of Lizards in the 
Collection of the British Museum,’ 1843, p. 127; and identical with 
Evesia Belli, described by Duméril and Bibron, ‘ Erpétologie Géné- 
rale,’ vol. v. p. 783. Both these descriptions are from the same 
specimen, which was in the collection of Mr. Bell, and which he 
presented to the French Museum. 
Freshwater Polyzoa in Australia. 
By C, D’Oyry H. Artin, Esq. 
To the Editors of the Annals and Magazine of Natural History. 
GENTLEMEN,—As I believe that up to this time the existence of 
freshwater Polyzoa in any part of Australia, or even in the southern 
hemisphere, is quite unknown to naturalists, I am gratified at being 
able to announce that within the last week I have found several spe- 
cimens, comprising at least two species, each belonging to a different 
enus. 
2 One is a Plumatella, with elongated statoblasts (free), closely 
resembling the figure of those of P. emarginata in Dr. Allman’s . 
Monograph, pl. 7. fig. 7. 
The other is unlike any figure in the above-named work. 
Both were found adhering to the under surface of fragments of 
basalt, near the margin of a clear sheet of water occupying the site 
of a deserted quarry close to the river Yarra, at Richmond, about 
two and a half miles from Melbourne,—the former also adhering to 
the inner surface of the bark of a dead stump of Hucalyptus, in a 
lagoon in the Zoological Gardens near Melbourne. 
They will both, I hope, be described and figured at an early date. 
Tn the mean time, I must content myself with this notice of their
