NOTES. 
In reference to the observations on Leptostoma, page 139., 1 may ob- 
serve, that this bird seems to have been described in France (some time 
after the specimen in question passed into the possession of the Zoological 
Society) under the name of Saurothera Botte. 
The great delay in determining the apparently undescribed species enu- 
merated in the systematic arrangement, and the lateness of their appear- 
ance, has prevented me from availing myself of some few ornithological 
publications ; as the late Numbers of the Zoological Proceedings, Gould’s 
Ornithology of New South Wales, &c. 
My suspicions that T. oréentalis was a distinct species from that found in 
Southern Africa, has been fully confirmed by specimens of the latter just 
brought home by Dr. Smith. M. Lichtenstein has evidently mistaken them 
for one, his measurements being those of the African, which he has thought 
to be the same as the Indian. M.Temminck, and Dr. Latham, have both 
fallen into the same error. As the case, therefore, now stands, I should 
| 
propose that the Cape species be distinguished by the name of 7. Capensis. _
