Mr. Frank W. Langdon describes and figures a supposed new 

 Warbler of the genus Helminthophaga, proposed to be called 

 H. cincinnatiensis , based on a single specimen obtained by the 

 describer in Ohio in May 1880. In a subsequent note Mr. 

 Ridgway suggests that this singular bird may be a hybrid 

 between Helminthophaga pinus and Oporornis formosa. 



36. Burbridge's ' Gardens of the Sun.' 



[The Gardens of the Sun : a Naturalist's Journey on the Mountains and 

 in the Forests and Swamps of Borneo and the Sulu Archipelago. By F, 

 W. Bui-bridge. 8vo. London : John Murray, 1880.] 



Mr. Burbridge is a w^ell-known collector of plants, and 

 gives us an interesting account of his journey via Labuan to 

 Northern Borneo and the Sulu Islands in quest of botanical 

 novelties. Two expeditions were made up the celebrated 

 mountain Kina Balou by diflFerent routes, in search of Pitcher- 

 plants {Nepenthes). On the Lawas river Mr. Burbridge met 

 with Lobiophasis bulweri and other fine Pheasants (see p. 61). 

 Mr. Burbridge reprints in an appendix the two papers pub- 

 lished by Mr. Sharpe (P. Z. S. 1879) on birds from Kina 

 Balu and the Sulu Islands. It would appear, however, from 

 ~"fr©«^-Mr. Burbridge's footnote (p. 359), that in the former 

 case the-specimens obtained by " Mr. Treacher's collectors" 

 were not got on the Kina Balou, but on the '' route between 

 Gaya Bay and Kivan (alt. 3000 feet)," where the ascent of 

 the mountain commences. It follows that we are, as yet, 

 very little acquainted with the birds of the elevated range of 

 Kina Balou.

[Beautiful and Curious Birds of the World. By Charles B. Cory, 

 F.L.S., F.Z.S., &c. Part i. October, 1880. Elephant folio. Boston, 

 Mass., U. S. A.] 



The contents of part i. of this work, which measures .2 feet 

 3 inches by 1 foot 10 inches, are figures of Didus inepdus and 

 Ptiloris paradiseus, and accompanying letterpress. 



We trust Mr. Cory will excuse us if we say, in our opinion, 

 the production of expensive illustrations of enormous size
