53. Sharpe and Wyatt on the Hirundinidse. 



[A Monograph of the Hirundinidaej or Family of Swallows. By R. 

 Bowdler Sharpe and Claude W. Wyatt. Pails XI.-XIV. 1889-90. 

 4to. London : Sotheran & Co.] 



The Monograph of the Swallows makes slow but constant 

 progress. Since we last noticed its advance^ two double parts 

 have been issued^ dated respectively December 1889 and 

 December 1890^ so that^ if the statements in the prospectus 

 are adhered to^ three or four more parts will complete the 

 work. 



The letterpress contains all that is known of the species 

 treated of, and the plates are generally well designed and 

 nicely coloured. 



Parts XI. and XII. (December 1889) contain figures of 

 the following species : — Cheramoeca leucosternum, Hirundo 

 badia, H. hyperythra, H. puella, H. dimidiata, H. savignii, 

 Cotile sinensis, Tachycineta cyaneoviridis, T. bicolor, Stelgi- 

 dopteryx uropygialis, Atticora fasciata, A. cyanoleuca, Progne 

 tapera, also maps of the distribution of Progne, Tachycineta, 

 and Stelgidopteryx. 



Parts XIII. and XIV. (December 1890) contain figures 

 of Stelgidopteryx serripennis, Petrochelidon pyrrhonota, P. 

 sivainsoni erythrogastra, P. spilodera, Cotile cincta, C. pa- 

 ludicola, Hirundo euchrysea, H. daurica, H. nipalensis, 

 H. erythropygia, Chelidon nipalensis, and Tachycineta al- 

 biventris. 



Petrochelidon sivainsoni erythrogastra is not a trinomial 

 name, but that of a supposed hybrid between Petrochelidon 

 swainsoni and Hirundo erythrogastra. We prefer Mr. Salvin's 

 way of writing it, " Hirundo erythrogastra x swainsoni (cf. 

 Ibis, 1888, p. 256) . 



54. Shufeldt on the Osteology of the Water-birds. 



[Contributions to the Comparative Osteology of Arctic and Sub-Arctic 

 Water-birds. Part VIII. By R. W. Shufeldt, M.D., C.M.Z.S., &c. 

 Journ. Anat, »& Physiol, xxv. p. 60.] 



The eighth part of Dr. Shufeldt^s " contributions " treats 

 of the appendicular skeleton of the Laridse and Stercorariidee.
