Professor Schlegel has also scut us the first part of a new 

 popular work* on the Zoology of Holland, of which he has 

 undertaken to wi'ite the portions relating to the Vertebrata. 



The Proceedings t of the Royal Danish Academy of Sciences 

 for the present year contain a paper by Professor J. Reinhardt 

 of Copenhagen on the nidification of the Anis {Crotuphaga), in 

 which he has carefully collected extracts from the different au- 

 thors who have written on this subject. The Professor considers 

 that there exist but three species of the genus, viz. Crotophagae 

 ani, major, and sulcirostris, — an opinion, we may mention, which 

 exactly agrees with our own views on this point. Professor 

 J. Reinhardt has also published some remarks J on the question 

 whether Picus tridactylus is to be considered a Danish bird, in 

 which he takes to task Dr. Kjserbolling's somewhat loose state- 

 ments on this point, and notices several discrepancies which 

 exist between the assertions made in the latter's " Danmarks 

 Fugle," and the accounts of the same occurrences given by the 

 same author in * Naumannia.'

The * Proceedings of the Academy of Natural Sciences of 

 Philadelphia,^ of which we have received up to p. 80 for the 

 present year, contain some notes on the habits of the Mexican 

 Humming-birds [Campylopterus delattrii, p. 47, and Cyano- 

 myia cyanocephala, p. 80), by Rafael Montes de Oca. We have 

 also to thank Prof. Baird and Mr. Cassiu for separate copies of 

 the first portion of the latter gentleman's catalogue of the birds 

 collected during the United States' expedition for survey of the 

 Isthmus of Darien. The locality is interesting and hitherto un- 

 explored. A new Pufi'-bird [Monasa pallescens), and the recently 

 described Toucan [Selenidera spectabilis) and Calliste {C. lavinia) 

 are among the most noticeable novelties. Mr. Cassin's Ortho-
