1364.] DR. P. L. SCLATER ON NEW PARROTS. 297 
STERNOTHARUS ADANSONII. 
Shell oblong ovate, depressed, rather wider behind than in front ; 
dark olive, with very close, regular, uniform radiating black lines, 
sometimes broken up into small dark spots; sternum and under- 
sides of the margin yellow; the areola of the sternal plate square, 
blackish. 
The head depressed, with very close, nearly uniform, unequal 
black lines; the frontal plate very large, with a triangular patch of 
small scales on the temple, reaching to over the front edge of the 
ears ; the lips white; the throat pale; the feet olive above, pale 
beneath ; claws 5/5, olive, with a yellow streak in the middle of the 
upper surface. 
The first vertebral plate much longer than wide, narrow behind, 
with a blunt keel ending in a rounded tubercle behind. The second, 
third, and fourth vertebree about as wide as long, with a sharp keel, 
ending in an acute tubercle near the hinder edge of each shield ; the 
fifth vertebra like the first, but only very slightly keeled. The 
front marginal plate wide, those over the hinder legs rather wider, 
and those on the sides of the shell very narrow. The gular plate 
small, triangular; the intergular one lozenge-shaped, narrowed in 
front ; the pectoral plates narrowed and truncated at the inner edges. 
Hab. West coast of Africa (Dalton). 
The species of this genus seem to have a confined range. Thus, 
there are two species of the first subgenus (Tanoa)—one from S. 
Africa and Natal, and the other from Western Africa; in the same 
manner there are two species of the second subgenus (Notoa)—one 
from Madagascar and the other from the West African coast. Thus 
1. Tanoa. 2. Notoa. 
S. sinuatus ...... S. and E. Africa........ S. subniger. 
S. derbianus...... West Africa............ S. adansonit. 
4. CHARACTERS OF TuoRrE New AMERICAN Parrots. By P. L. 
ScuatTer, M.A., Pu.D., F.R.S., SecRETARY TO THE SOCIETY. 
(Plate XXIV.) 
Mr. Otto Finsch, the lately appointed Curator of the Zoological 
Museum of Bremen, who has recently visited this country in order 
to obtain materials for the preparation of his work on the Psitta- 
cide, has furnished me with notes on three new American species of 
this interesting group of birds. Two of these are discoveries made 
many years ago by the late Johann Natterer in Brazil, although they 
have not yet been published, and I shall describe them under Nat- 
terer’s MS. names. To the third species I propose to attach the 
name of Mr. Finsch, whose monograph of the Parrots, to which he 
has devoted much time and toil, will shortly be published.
