Mr. Bennett availed himself of the opportunity to remark that the 

 Serranus, characterized by him from this collection on the 23rd of 

 August, as the Serr. Telfairii*, had been described about the same 

 time by MM. Cuvier and Valenciennes under the name of Serr. 

 argyro-grammicus. He also stated, that those eminent zoologists 

 having used as the designation of a distinct genus of Scombrida from 

 that to which he had applied itf, the classical name Apolectus, 

 he proposed, with the view of preventing confusion, to apply to the 

 group indicated by him the name of Apodontis. 



Mr. Bennett subsequently observed, that the Birds described by 

 him \, had during the summer completed the change of their plumage, 

 and had thereby assumed the full adult characters of the Angola 

 Vulture of Pennant, Vultur Angolensis, Gmel. The Pobjborus? 

 hypoleucus sinks therefore into a synonym, and the description of it 

 is that of the Angola Vulture in its change from immature to adult 

 plumage. 



Mr. Owen read the following additional Notes on the anatomy of 

 Crocodilus actitus, Cuv., taken at the dissection of the female of that 

 species, which lately died at the Society's Gardens. 



" The same subdivision of the serous membranes, as was noticed 

 in the dissection of the male§, was again observed ; and in addition 

 to those cavities previously described, another distinct one was found 

 between the back part of the liver and oesophagus. 



"The interior of the stomach did not present the distinct patches 

 observable in the previous dissection (and still obvious in the prepa- 

 ration), which must therefore be considered as an accidental variety : 

 but the lining membrane was a smooth uniform villous surface, stained 

 of a yellow colour, and highly vascular, as is proved by injection of 

 size and vermilion. 



"The small intestines presented a dilatation immediately beyond 

 the folds of the duodenum ; which is most probably a normal structure, 

 and not depending on the accumulation ofjlatus, as was supposed in 

 the dissection of the male. 



"The spleen was in the same relative situation, and exhibited the 

 same loose mode of connection, but the process of peritoneum was 

 somewhat broader. On holding it up to the light an equally satis- 

 factory view of its contents was obtained ; and I am therefore inclined
