64. Gadoio on the Myology of the Ratitce. 



[Ziu' vergleichenden Anatomie der MiiskulatLu- des Beckens imd der 

 hinteren Gliedmasse der Ratiten. Vou Haus Gadow, Dr. Phil, Jena: 



leso.j 



In this large quarto paper of fifty-six pages, Dr. Gadow 

 describes at length, from his own dissections, the muscles of 

 the pelvis and hind limb of the genera Struthio, Rhea, and 

 Casuarius, particular attention being given to the nervous 

 system. The myology of Apteryx is compared with the 

 other three genera, from Prof. Owen's description of that 

 bird in the Zoological Society's ' Transactions.' Five tinted 

 plates illustrate the more important points touched upon. 

 We regret that Dr. Gadow has not added a precise summary 

 of the results arrived at as to the leading myological differ- 

 ences between the forms which he has examined.

[Apuntes para la Fauna Puerto-riquena, por Don Juan Gundlach. 

 Anal, de Hist. Nat. vii. pp. 135, 343 (1878).] 



The well-known naturalist of Cuba, Don Juan Gundlach, 

 has made two expeditions to Porto Rico. Of the first of these, 

 which took place in 1873, so far as regards the birds, the 

 results have been already published in the ' Journal fiir Or- 

 nithologie' for 1874. In 1875 this ardent collector made a 

 second expedition to the same island, and visited various 

 points to which he had not penetrated in his former journey. 

 The present memoir contains the results of his last expe- 

 riences added to his previous knowledge of the same subject. 

 After a preliminary account of former authorities upon the 

 birds of Porto Rico, the author presents us with a very com- 

 plete essay on its avifauna. According to Gundlach, the 

 birds now known to exist in Porto Rico are 153 in number, of
