Id another paper, on the genus felis, he gives the osteolo- Feline genus, 

 gical characters of the head in the principal species; and 

 has made known a species not distinguished by modern 

 naturalists. To this he has given the name of leopard. Leopard, 

 which had become synonimous with panther, for want of 

 being able to apply it with precision. It dijQTers from the 

 latter in being of a smaller size, and having a greater num- 

 ber of spots, 



Mr. Geoffroy long ago made a particular division, under Classification 

 the name of ateles, of the apes without thumbs, which had °^^P^» 

 been confounded with the sapajous, from the prehensile 

 tail common to both. He has now added two new species Two new spc- 

 to those he had already made known, and given figures and ^^^* 

 descriptions of them. One of them, which he names aracb- 

 noides, had been merely mentioned by Edwards and 

 Brown. The other, which he terms encadree is altogetber 

 new. It is black, with white hairs round the face. 



The same gentleman has described two birds; one im- OmUhoIogy. 

 perfectly known, the other new. The latter has some re- ^ 



semblance both to the corvus nudus and the c. calvus ; but 

 there are sufficient differences between them to form three dis- 

 tinct genera, under the names of cephalopterus for the new 

 species, gymnoderus for the c. nudus, and gymnocephalus 

 for the c. calvus. 



The cephalopterus is black, with a very high crest, which Cephalopte. 

 falls forward on the beak, and a kind of dewlap also covered ^^^' 

 vith feathers. Each of these is of a metallic violet colour. 



The other bird, which had been imperfectly described by Microdacty- 

 Marcgrave under the name of cariama, Mr. G. had consi- 

 dered from his description as approaching to the trum- 

 peter; but now he has seen it in the Museum of Natural 

 History he classes it as a separate genus under the name of 

 microdactylus. 



The tortoises have furnished Mr. G. with the subject of Tortoises, 

 another interesting paper. Having seen, while in Egypt, 

 the tortoise of the Nile, mentioned by Forskaol, he was led 

 to form a particular genus of all those, which like it have 

 the extremities of the ribs separate, and a soft shell. He 

 names it trionix, and has added to it severa'l new species.
