esteemed fellow-worker bearing upon a concise and simple 

 method of recording ornithological observations^ his text 

 being then the occurrence of the Black Redstart {Ruticilla 

 titys) at Pentland Skerries. In the present papers he has 

 selected as his theme the Little Gull {Larus minutus), which 

 has been killed in North Uist — apparently the most westerly 

 locality as yet recorded in Europe. 



81. Martorelli on the Fauna of Sardinia. 



[OsseiTazioni sui Mammiferi eel Uccelli fatte iu Sardegna dal Dott. 

 Giacinto Martorelli. Small folio. Pistoia : 1884.] 



In this useful addition to our knowledge of the Birds of 

 the island of Sardinia we have a coloured illustration of an 

 immature example of a Falcon which has been pronounced 

 by Mr. J. H. Gurney to be Faico punicus {cf. Salvadori, 

 infra, p. 462). There is also a coloured plate of a prettily 

 placed nest of the Grey Flycatcher [Butalis grisola), over- 

 hung with the maidenhair fern^ and an outline illustration of 

 heads and feet of various groups. We cannot always agree 

 with the learned Doctor in the orthography of his scientific 

 names, such as Haegilites for ^gialitis.

[Revue Comparative de laFaune Ornithologique des Gouvernements de 

 Moscou et de Toula. Par Michel Menzbier. Bull. Soc. Imp. Nat. Moscou,

The writer, who had already published (Bull. Soc. Imp. Nat. 

 IMoscou, 1879) a paper on the Birds of the Government of 

 Toula, which is situated nearly due south of that of Moscow, 

 now gives a columnar list of the 266 species found in both 

 these districts. This is followed by a catalogue of 259 

 species obtained between the Volga and the Oka, with very 

 interesting remarks upon their geographical distribution. 



83. Menzbier on the Extinction of Species through Crossing.

 dans I'extiuction des Especes. Par M. Michel Menzbier. Revue Scient.
