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

 Serratvts, characterized by him from this coUection on the 23rd of 

 Augusi, as the Serr. Telfairii (p. J 27), had been described about the 

 šame 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 it (p. 146), the classical name Apoleclust 

 he proposed, wilh the vievv of preventing confusion, to apply to the 

 group indicated by him the name of Jpodontis. 



Mr. Bennett subsequently observed, that the Birds described by 

 him (p. 13), had duiing the summer completed the change of their 

 plumage, and had thereby assumed ihe fuU adult characters of the 

 Angola Fulture of Pennant, Vutiur Angolensis, Gmel. The Poly- 

 borus? hypoleuciis smVs. therefore into a synonym, and the description 

 of it is that of the Angola Fulture in its change from immature to 

 adult plumage. 



> Mr, Owen read the following additional Notės on the anatomy of 

 Crocodilus acufus, Cuv., taken at the dissectioti of the female of that 

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



" The šame subdivision of the serous membranes, as was noliced 

 in the dissection of the malė (p. 139), was again observed ; and in 

 addition to those cavities previously described, another distinct one 

 wa8 found between the back part of the liver and asophagus. 



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

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

 ration), which mušt 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 intestine^ presented a dilatation immediately beyond 

 the folds of the duodenum ,• vvhich is niost probably a normai structure, 

 and not depending on the accumulation ofjiatus, as vvas supposed in 

 the dissection of the malė. 



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

 šame loose mode of connection, but the process of peritoneum vvas 

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

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

 to consider it an expeiimentum crucis on the ncgative side of the 

 •picstion regarding the duct of the spleen.
