two years ago along with other skins from Celebes, without 

 any more definite locality. Geocichla fronialis appears to be 

 most nearly related to G. erythronota Sclater, but to diflfer 

 in its black forehead ; it ma}'^ however, possibly be only a 

 fully adult male of the latter species. 



79. Nehrkorn's Catalogue of his Egg-collection. 



[Katalog der Eiersammlung, nebst Beschreibungen der aussereiiro- 

 piiischen Eier. Von Adolph Nehrkorn. 8vo. Braunschweig, 1899.] 



The great Collection of Eggs of Herr Nehrkorn, of 

 Riddagshausen, near Brunswick, is known to many English 

 ornithologists, as is likewise the kind hospitality of its 

 owner. Herr Nehrkorn has long been engaged on an 

 account of his collection, and has now brought his labours 

 to a successful conclusion in the volume before us. 



The collection, which is one of the largest, if not quite 

 the largest on the Continent, and is surpassed in extent only 

 by that of the British Museum *, and perhaps by that of 

 Mr. Philip Crowley, in England, contains examples of the 

 eggs of 3546 species of birds. These are arranged and 

 named in this work according to the British Museum 

 * Catalogue of Birds,^ and references are given to the 

 volumes and pages of the Catalogue throughout the list. 

 Besides the name of the species the general locality is 

 given, but the number of specimens of each species and 

 their exact localities are only occasionally inserted. Short 

 but most useful descriptions are added of the eggs of 

 exotic species, and at the head of the genera and families 

 the general character of the eggs of the group is in many 

 cases summarized. Among the special rarities of the collec- 

 tion we observe eggs of Ccereba cyanea from Amazonia 

 (of an almost uniform black) ; of Lophotriccus sqiiamatus 

 (most beautifully zoned with rich red) ; of Eurystopodus 

 nigripennis (a Goatsucker from the Solomon Islands) ; of 

 a Toucan {Pteroglossus fiavirostris) , the first of this family 

 described, so far as we know ; and of two Touracous. These 

 eggs have attracted our notice on turning over the pages of
