is the same. M. Mulsant adheres to his terms "machoire" 

 for what we prefer to call the mandible of the beak, and 

 " raandibule " for the upper mandible or maxilla, which is to 

 be regretted, as ornithologists are not likely to adopt his no- 

 menclature. A Latin description is given of each species as 

 well as a French one. Minute measm'cments and full synonymy 

 with references make this part of the work very complete. 

 The geographical distribution of each species is also given ; 

 this is of coui'se much more ample than in the former work, 

 and, we are happy to add, more accurate ; still we see room 

 for improvement. We can hardly accept Guatemala as com- 

 prised within the range of Euioxeres aquila Avithout good 

 authority ; nor can we credit the statement that Pliaethornis 

 eurynome occurs in Chili ; nor do we believe that Campylo- 

 pterus parnpa inhabits New Granada, it ha\Hng not hitherto 

 been found southward of the limits of Guatemala. 



M. Mulsant does not follow ]Mr. Gould in his excessive 

 multiplication of species, but goes fuither than any one has 

 yet done in uniting birds hitherto supposed to be specifically 

 distinct. We are not disposed to demur to this treatment, 

 especially as all the so-called races or varieties are mentioned 

 separately in the text attached to the species to which they 

 are said to belong. Having thus briefly noticed the chief 

 features of ]\I. ]\Iulsant's work, which will, when finished, be 

 of great use to those studying this fascinating group of birds, 

 we wish him all success in his undertaking. 



After a long interval Professor Schlegel has resumed the 

 issue of his well-known work, the ' INIuseum d'Histoire Na- 

 turelle des Pays-Bas ^^, the 10th livraison of which was pub- 

 lished last year. The contents include the Aves Struthiones, 

 the Columbse, and a re^-iew of the Rapaces. 



In continuing to place the Dodo and its allies with the 

 Struthiones, Prof. Schlegel occupies what must, we believe, 

 be now considered an isolated position — all who have recently 

 studied the remains of these remarkable birds, with one accord
