mark-able in the normal Tinamine skull is entirely lacking, 

 and the interorbital portion of the cranium is much con- 

 tracted. Also the first three dorsals are fused into one mass, 

 and other peculiarities exist. It is unfortunate that Mr. Lucas 

 has no skeletons of other forms of Tinamous to aid him in 

 his comparisons. 



10, Meyer on the Caper caillie and Black Grouse. 



[Unser Auer-, Rackel- und Birkwild uud seine Abarten ; von Di*. A. 

 B. Meyer. Text, folio ; Atlas, Elephant folio (17 plates). Wien: 1887.] 



Dr. Meyer has devoted a folio volume of 96 pages and an 

 accompanying larger Atlas with 17 coloured plates to the 

 consideration of Tetrao urogallus and T. tetrix and their 

 various crosses : inter se, and with allied forms of Grouse. 

 The number and variety of these forms is certainly worthy of 

 careful study, and is here exhaustively treated of. The 

 figures are drawn by Miitzel, and well printed in colours. 



11. Milne-Edwards and Oustalet on the Birds of Grand 

 Comoro Island. 



[Observations sur qiielques especes d'oiseaux r^cemment decouvertea 

 dans I'ile de la Grande Comoro. Par MM. Alph. Milne-Edwards et 

 E. Oustalet. Ann. Sc. Nat. Zool. ser. \ii. t. ii. pp. 213-238 (1887).] 



In 1885 M. Humblot brought from the island of Grand 

 Comoro an important collection of birds, of which a short 

 account was published by the authors of the present paper in 

 the ' Coraptcs Rendus ' (Compt. Rend, Ac. Sc. 1885, i. CI, 

 p, 218). A more complete account is now given of this 

 collection, and of a second, still larger one, brought by this 

 collector from the same island. 



Fourteen specimens are treated of in the present com- 

 munication, all of which were described as new by the 

 authors in their first paper on this subject in the ' Comptes 

 Rendus,' Two of these are now identified with other species, 

 but twelve are regarded as well founded. 



The total number of species of which examples were ob- 

 tained by M. Humblot in Grand Comoro was 33.
