Among the forms peculiar to India was observed a second spe- 

 cies of the singular group which contains the Horned Pheasant, or 

 the Meleagris Satyra of Linnaeus, and which has been lately sepa- 

 rated by M. Cuvicr under the name of Tragopan. Its specific cha- 

 racters are ; 



TRAGOPAN HASTINGSII. Trag. dorso brunneo : fusco undulato, 

 abdomine intense rubro, amborum plumis ad apicem nigris in 

 media albo guttatis ; cristd crissoque alris, ilia ad apicem coccined, 

 hoc albo maculato ; collo posteriori coccineo ; thorace aurantio ; 

 regione circumoculari nudtt, carunculisque pendentibus luteis ; 

 caudd atrd, lutescenti-albo undulatd. 



A species of true Pheasant, which seems to have been indicated 

 by former writers from incomplete descriptions or drawings, but 

 never to have been accurately characterized, was also exhibited 

 and named. 



PHASIANUS ALBO-CRISTATUS. Mas. Phas. supra ater, viridi 

 nitore splendens ; dorso imo albo-Jasciato cristce plumis albis, 

 elongatis, deorsim recumbentibus, basi subfuscis ; remigibus cor- 

 poreque inferiorijuscis ; pectoris plumis lanceolatis albescentibus. 

 Fcem. Corpore supra cristdque breviorijvscescenti-brunneis; ab- 

 domine pallid iore ; guld, plumarumque corporis apicibus et rha- 

 chibus albescentibus ; rectricibus lateralibus atris, mediis brunneis 

 albescenti undulatis. 



A third species was likewise added from the collection to the 

 group of Enicurus of M. Temminck, which has hitherto been con- 

 sidered as limited in range to the Indian Archipelago. The fol- 

 lowing are its characters : 



ENICURUS MACULATUS. En. capite, collo, dorso superiori, pec- 

 tore, ptilis, remigibus secundariis, cauddque intense atris ; frontis 

 notd latd, maculis confertis nuchce et sparsis dorsi, pteromatibus , 

 dorso imo, abdomine, rectricibus lateralibus, mediarumque apici- 

 bus albis ; remigibus primariisjuscis ; rostro nigro ; pedibus al- 

 bescentibus. 



Statura En. specioso sequalis. 



Mr. Owen resumed the reading of his paper On the Anatomy 

 of the Orang Utan (Simia Satyrus, L.) This part of the com- 

 munication is devoted to the osteology of the animal, which is 

 minutely described and contrasted with that of the Chimpanzee. 

 With the skeleton of the Pongo (Pongo Wurmbii, Desm.) the re- 

 semblance is in many particulars almost complete j and the exten- 

 sive examination which Mr. Owen has made of entire skeletons of 

 both the Pongo and the Orang, and of numerous crania of the 

 latter at various ages, has led him to adopt the opinion of those 

 who maintain that these constitute really but one species, of which 

 the Orang is the young, and the Pongo the adult. The remarkable 

 differences in the crest of the cranium, and in the facial angle, 

 appear to be the result of the action of the powerful muscles of 

 nianducation, and of the developement of the extremely large 

 laniarii. 



A marked peculiarity of the cranium of the Orang exists in 

 the junction of the sphenoid with the parietal bones; a junction 



which
