described by Professor Owen in his " Memoirs on the Di- 

 nornis."* The small oval bone found along with the other 

 bones is evidently a tracheal ring ; it measures T 8 oths of an 

 inch in length, by ^jths of an inch in breadth, and is about 

 r Vth of an inch in depth. 



A portion of a vertebra, which has been deprived of its 

 calcareous matter by dilute acid, would seem to prove, by the 

 large amount of residual organic matter, that these fossil bones 

 are probably of recent origin. 



It is to be hoped that this interesting collection will ulti- 

 mately assist in the construction of one of the species of Pa- 

 lapteryx, indicated by Professor Owen from the examination 

 of detached crania, or founded upon the proportions and ana- 

 tomical differences of other separate parts, or single bones of 

 the skeleton. 



III. Notice of the " Angwantibo" of Old Calabar, Africa; an Animal 

 belonging to the Family Lemtjrina ; and apparently to the Genus 

 Perodicticus, of Bennett. By John Alexander Smith, M.D. 



The interesting little animal (now exhibited) was given 

 to me by Mr William Oliphant, who received it some time ago 

 from the Rev. Alexander Robb, one of the U. P. missionaries 

 at Old Calabar. The following extract from a letter, dated 

 Old Calabar, 1st December 1859, gives some details concern- 

 ing it: — "I was at Creek Town yesterday, and received from 

 ' King Eyo Honesty' a small bush animal ; or, as the Krumen 

 call it, i bush meat,' which I brought with me to give to Mr 

 Thomson, who is with us for a day or two, as he takes a great 

 interest in these matters. He, however, advised me to bottle 

 the animal, and send it to you myself ; which, therefore, I now 

 do with pleasure. We have put it up so that it ought to reach 

 you in safety. It is in a stoppered bottle, well sealed, and 

 the bottle is put up in a small tin box wrapped up in our 

 native grass cloth. It seems to be a lori, or Sienops tardi- 

 gradus. The Calabar people call it Angwantibo (Angwdn 

 means a farm), but we do not know the etymology of the second 



* This bone was afterwards compared with the skeletons of Aptcryx and 

 Dinornis in the British Museum, and found to be a left fibula.
