“ This species is closely allied to A. maritima, but is dis¬ 
tinguished by its leaden-brown plumage and white superciliary 
streaks, as well as by the increased amount of white on the 
tail-feathers.” 
Dr. Bowdler Sharpe exhibited a specimen of the rare 
Bubo letti, Biittik., from the Rio Benito, French Congo, 
obtained by Mr. G. L. Bates. The species had been originally 
described by Dr. Biittikofer from Liberia, and placed by him 
in the genus Bubo . The present specimen, however, had 
been examined by Mr. Pycraft for its pterylography, and 
Dr. Sharpe, judging by its external characters, concurred 
with him that it belonged to the genus Scops , and should 
be known as Scops letti (Biittik.). 
Another interesting bird procured by Mr. Bates was a 
white-spotted Crake, which did not seem to be quite the 
same as Canirallus oculeus of the Gold Coast. It was identical, 
however, with the bird from the Cameroons, and Dr. Sharpe 
had already referred (Cat. B. xxiii. p. 73) to the differences 
exhibited by the birds of the latter country. He therefore 
proposed to describe the Crake from the French Congo and 
the Cameroons as 
Canirallus batesi, sp. n. 
Ad. Siinilis C. oculeo, sed saturatior, dorso saturate olivas- 
centi-brunneo, nee virescenti-olivaceo: pileo sordid^ 
brunneo, nee rufescenti-brunneo : fronte et facie laterali, 
sicut in C. oculeo , cinereis; regione auriculari quoque 
cinerea. Long. tot. 110 poll., culm. 1*35, alae 6’3, caudae 
2’4, tarsi 1*95. 
Among other interesting birds obtained on the Rio Benito 
on the same occasion were examples of Bubulcus lucidus and 
Calopelia brehmeri. 
Dr. Sharpe likewise exhibited a specimen of a Goshawk 
from British Guiana, from the collection of Mr. F. V. 
McConnell. Feeling sure that it was Astur jardinii of 
Gurney (Ibis, 1887, p. 96, pi. iii.). Dr. Sharpe had sent the 
specimen to Mr. James Reeve, the Director of the Castle
