on Feb. 8tli, 1898, with a collection of 3075 birds — not to 

 speak ol" tortoises and other specimens. After a short 

 general introchiction, the diaries and ficld-n()L'\s of Mr. Harris 

 and jNIr. F. P. Drowno nre printed at full length. They are 

 well wt)rthy of perusal. 



In the general remarks on the fauna of the (Jalapagos, 

 which follow, the authors show more clearly than ever that 

 the bird- life is entirely of American origin, without any sort 

 of admixture. As regards the somewhat far-fetched theories 

 of Dr. Banr, they prefer to leave the questions as to the 

 supposed former connection of the islands with each other 

 and with the continent as "uncertain^': we may say de- 

 cidedly " not })roven.^' 



In the leview of the 108 species of birds now known to 

 compose the avifauna of the Galapagos, which concludes the 

 memoir, the anthors have had the use of the Baur Collection 

 of 1100 skins, as well as of that made by Mr. Harris. They 

 acknowledge the assistance received from Mr. Ridgway^s 

 excellent essay on the ' Birds of the Galapagos Archipelago,^ 

 but do not agree to all his conclusions. Most of the new 

 species and subspecies based on Mr. Harris's collection have 

 been already characterized in the ' Bulletin of the B. O. C.,' 

 bnt the following are now added •.■—Certhidea olivacea riily- 

 ivayi, Geospiza scandens septentrionaUs, Nesopelia yala- 

 pagoensis exsul, and Creciscus sharpei. 'V\\e most notable 

 discoveries made by Mr. Harris seem to be the Short-winged 

 Cormorant, Phulucrocorax harrisi, and the abundauce of 

 Xema fnrcata in the Galapagos, whence it has been known to 

 wander to the coast of Peru ; it has also been obtained on 

 the volcanic island of Malpelo, in about lat. 4 N. [c/. Ibis, 

 1896, p. 286].
