540 Coaiit. T. Salvador! on 



researches (of whicli only Rallus insignis, Sc\., seems to be 

 peculiar) I have to add Esacus magnirostris , Limosa melanu- 

 roides and L. uropygialis, Phalaropus angustirostris, Tringa 

 minuta and another species of Tringa, all temporary visitors 

 to this country^ besides Ardea sinensis. Of the Porphyrio I 

 obtained only a young one, not sufficient to determine the 

 species, which will, however, be a known one. Strange to say, 

 I never observed Strepsilas interpres, although this bird, no 

 doubt, also visits these shores. Ardea sacra is very rare. 



Of the Natatores Mr. Brown sent home only Sterna fuli- 

 ginosa and Anous stolidus ; but I can add six species more, 

 namely Sterna bergii, S. longipennis, S. melanauchen, S. 

 sinensis, Sula fusca, and Tachypetes aquilus. I have never 

 seen a Gygis nor a Phaeton, nor any member of the Procel- 

 lariidse here. Very strange is the absence of Ducks, espe- 

 cially oi Dendrocygna ; but it is likely they may occur in the 

 interior or on the rivers in the southern portion of the 

 island.

XLII. — More about Cypselus horus, H. et F. 

 By T. Salvadori, C.M.Z.S. 



In 1872 the Marquis Antinori and I jointly published a paper 

 on Cypselus horus, H. et F."^, showing that the bird so named 

 was not a variety of C. affinis, as von Heuglin f had thought, 

 but a perfectly distinct species. We gave a full description of 

 it, and pointed out the characteristics by which it may be 

 distinguished from the allied species, C. affinis, J. E. Gr., and 

 C. cafer, Licht. Quite recently Count Turati, of Milan, has 

 sent me for inspection a Cypselus from Landana (Congo), 

 collected by Dr. Lucan and M. Petit, and received through 

 M. Bouvier. Although this specimen is not fully adult, 

 it is quite evident, in my opinion, that it belongs to the 

 same species as the specimen in the Turin Museum which
