Report on 



discoveries of this naturalist Morphnus hastatus, Less, of Ben- 

 gal ; the Circus rufus of Bengal ; the Melias tristis, Less, of 

 Pegu ; the Cuculus lugtibris, Horsf. the female from Java; 

 the Picus cavente. Less, of Pegu, where it is called Temaga- 

 oume ; Edela rujiceps. Less, of Java; Lanius collurioides, 

 Less, of India ; Lanius sordidus. Less, of Pegu ; Garrulax 

 Belangeri, Less, of Pegu ; and G. rvfifrons^ Less, species 

 which the author has isolated under the generic name of 

 Garrulax, because they form a very distinct type, according 

 to M. Lesson, which ought to find a place in the family of 

 Cassicans after the Myophone, and in the group of Chouca- 

 ris ; the Muscicapa (muscylva) albogularis, Less, of Pondi- 

 chery ; the Pastor peguanus, Less. ; the Fringilla pyrrhop- 

 tera, Less. ; the Francolinus spadiceuSf Less. (Perdix spadiea, 

 Lath.) from the vicinity of Pondichery ; finally the Otis aurita^ 

 Lath, and the Chenelopex coromandelianus^ Less. These 

 species are worthy of the interest of naturalists, and many of 

 them have been figured in the Atlas volume of plates, of 

 which there are ten dedicated to Ornithology. 



M. Lesson was also charged with the publication of the 

 Reptiles, apparently consisting altogether of species collect- 

 ed by M. Belanger ; these to the number of thirty-three be- 

 long to sixteen genera, of which we find one new genus allied 

 to Trionyx, which he has named Tetraonyx, characterized 

 by a broad membrane between the toes, which are four, all 

 supplied with nails. M. Lesson takes occasion also to furnish 

 descriptions of certain species of Hydrophis, which he pro- 

 poses to unite with the Ophidiens in a family which he calls 

 Nauticophis ; this family he proposes to divide into two 

 tribes, including the five genera into which these animals 

 appear to be separated. 



Amongst the most remarkable Reptiles which science owes 

 to the travels of M. Belanger, we may mention a species 

 of Emys dedicated to this traveller. The species upon 

 which the genus Tetraonyx is founded, the long-necked
