M. Leon Vaillant describes a new genus of fishes from the Caroline 
Islands of which there are now two individuals at the Paris Museum. 
This fish resembles Fierasfer of Cuvier, but differs from it in the size 
of the dorsal fin, and more particularly in the character and position 
of its scales. In the Caroline genus the scales are distinctly separate, 
large in proportion and form a sort of network with lozenge-shaped 
meshes over the body; they are not imbricated, but merely touch, end 
forend. It is this singular arrangement of the scales that leads Mr. 
Vaillant to create a new species to which he refers these fish with the 
` specific name Rhizwketicus carolinensis. (Revue Scientifique, Dee. 
1893.) 
A list of the Mammals of Rio Grande de Sul published by Dr. 
Herman von Ihering shows the following distribution : Marsupialia 
11; Diplarthra 8; Cetacea 2; Edentata6; Glires 24; Chiroptera 17; 
Carnivora 19; Pinnipedia 2; Quadrumana 3. (Rio Grande de Sul, 
20, IV, 1892.) 
From certain cranial and dental peculiarities, Mr. C. Hart Merriam 
considers the Yellow Bear of Louisiana a species distinct from Ursus 
americanus Pallasand U. horribilis Ord. He gives a description based 
on five skulls from Morehouse Parrish, Louisiana, and claims for it 
the name U. luteolus, given by Griffith in 1821. (Proceeds. Biol. Soe. 
Wash., Dec., 1893.) He thinks it is the Cinnamon Bear of Audubon 
and Bachman, but of this there is much doubt, 
Two new species are added to the list of Mammals from East Africa, 
a dormouse, Eliomys parvus, closely resemblingj E. kellenii, and a mouse 
Mus tana, allied to M. musculus. Both species are described by Mr- 
Frederick True in the Proceeds. U. S. Natl. Mus., 1893.
