In No. 137 Mr. Ridgway shows tliat Cathartes burro- 

 vianus of Cassin is the same as C urubitinga of Pelzchi (ex 

 Natterer), Gassings name having the priority. In No. 138 

 we learn that Mr. Hidgway has solved the long-existing puzzle 

 of Onychotes gruberi, by proving that tliis supposed Californian 

 species (see Ibis, 1881, p. 39G, pi. xii.) is no other than Buteo 

 solitarrus of the Sandwich Islands, He states in No. 139 

 that, although smaller than any example in the National 

 Museum, B. oxypterus is unquestionably referable to B. 

 swainsoni. But the specimen described in ' North- American 

 Birds' (iii. p. 266) as the melanistic adult of " B. swainsoni, 

 var. oxypterus," is not B. sivainsoni at all, h\xi B . fuUginosus , 

 Scl., "which is said (and probably with truth) to be the 

 melanistic phase of B. brachyurus." In No. 140 the Boat- 

 billed Heron of Central America, from Mexico to Veragua, 

 is separated as a new species, Cancroma zeledoni, differing 

 from C cochlearia in having the neck and breast deep buff 

 instead of ashy white, the upper parts of a deeper grey, and 

 the crest far less developed. In No. 141 Rupornis gracilis, as 

 it is proposed to call the new species from Cozumel, is de- 

 scribed as similar to R. ruficauda griseicauda, but decidedly 

 smaller, and with the thighs and under wing-coverts nearly 

 or quite immaculate. Lastly, the specimens of Peuccea from 

 Texas referred to P. arizona by Messrs. Kidgway and Merrill 

 in their joint article on the ornithology of Southern Texas 

 (Proc. U.S. Nat. Mus. i. p. 127) turn out to be the same as 

 Coturniculus mexicanus, Lawrence (Ann. Lye. N. Y. viii. 

 p. 474), from the mountains of Colima. The species must 

 therefore stand as Peuccea mexicana. 



143. Salvadori and Giglioli on new Birds from Cochin 



China. 



[Due miove specie di Uccelli della Cocincina raccolte durante il viaggio 

 della R. Pirofregata Magenta e descritte da T. Salvadori ed E. Giglioli. 

 Atti R. Accad. Sci. Torino, xx. p. 427.] 



An apparently very conspicuous new species of Cissa (C. 

 hypoleuca) and a new Mirafra {M. erythrocephala) are de- 

 scribed from specimens collected in Cochin China in 1846, 

 during the voyage of the ' Magenta ' round the world.
