300 Miscellaneous. 
The anatomy of the eye and ear is fully described in the 
original paper, together with that of the digestive, nervous, 
and vascular systems; in connexion with this last, remarkable 
vascular retia were found, situated in the axillary, submaxillary, 
and cervical regions.

Notice of a new Species of Spider Monkey (Ateles Bartlettii) in the 
British Museum. By Dr. J. E. Gray. 
Mr. Epwarp Bart ett, who is collecting specimens on the banks 
of the Amazons, has sent home a new and beautiful species of 
spider monkey, which I propose to call Ateles Bartletti, in honour 
of the father and sons. Every one acquainted with the father knows 
_him as a most careful and accurate observer and most obliging per- 
son; and I believe his sons are following in his footsteps. 
Ateles Bartlettii may be thus distinguished :— 
Fur abundant, long, and soft. Black ; the cheeks white, a band 
across the forehead over the orbits bright reddish yellow ; the chest, 
belly, inner side and front and back of the limbs, and the sides and 
under surface of the tail yellow. 
Hab. Brazil, the upper part of the Amazons (Bartlett). In Brit.

Note on a Species of Planarian Worm hitherto apparently not 
described. By the Rev. W. Hoveuron, M.A., F.L.S. 
To the Editors of the Annals of Natural History. 
GENTLEMEN,—I have recently met with a form of Planarian 
worm which I am unable to identify with any described species, 
either in Diesing’s ‘ Systema Helminthum’ or in Johnston’s ‘ Cata- 
logue of non-parasitic Worms in the British Museum.’ It belongs 
to the family of Dalyellidee, and is a species of the genus Typhlo- 
plana, Hemp. & Ehrenb. Diesing (Syst. Helminth. vol. i. p. 231) 
enumerates four freshwater species of this genus; and Dr. Johnston 
admits two into the British fauna, viz. T. feecunda and T. prasina, 
the first of which is white, the second of a beautiful grass-green 
colour. My specimens are almost entirely black, except at the mar- 
gins near the head. I find them within the stems of Sparganium in 
a weedy reedy pond where other Planariz (such as Polycelis nigra 
and P. brunnea, Planaria lactea and P. torva) are common. The 
species, which I believe to be new, occurs sparingly. Diesing’s 
definition of the genus is as follows :— 
* Corpus oblongum, teretiusculum. Caput corpori continuum. 
Os centrale v. subcentrale. Ocelli nulli. Aperture genitales.... 
Aquarum dulcium, rarissime maris incolee.”’ 
The species, which I propose to call Typhloplana nigra, may be 
thus described :— 
Body rounded anteriorly, tapering to a point behind; colour deep
