papillce, wliich increased in size and length, but diminished in num- 

 ber, towards the root. The epiglottis was large and broad ; the 

 rimą gloltidis long ; and from the arytenoid cartihiges tvvo processes 

 extended backwards, having a triangular flattened surface ending 

 in a point." 



The body of one of the Society's specimens of the Razor-billed 

 Curassou), (Ourai Mitu, Cuv.,)was laid on the table, and Mr. Yar- 

 rell pointed out the peculiarities of its very e\ongated trachea, vvhich 

 is produced between the skin and the museles beyond the sternum, 

 and reaches ahnost to the vent. It has been figured by Dr. Latham, 

 M. Temminck, and others. Mr. Yarrell displayed the sterno-tra- 

 cheal museles extending along the whole of the tube, and remarked 

 that this disposition prevail», with one or two exceptions, in all 

 birds in which the fold of the trachea is not included in bone. In 

 those birds, on the contrary, in vvhich the prolongationof the f rac^ea 

 enters a cavity in the sternum, (as for instance in the Hoopers Cygnus 

 ferus and Cygn. Betvickii,) the sterno tracheal museles pass from 

 the entering portion of the tube to that vvhich has just left the bone, 

 and are not continued along the fold of trachea included vvithin the 

 bone. 



A portion of a large collection of Fishes from the Mauritius, pre- 

 sented to the Society by Mr. Telfair, vvas exhibited ; and Mr. Ben- 

 nett called the attention of the Committee to the species of Midlet 

 contained in it. These vvere eight in number, and belonged to the 

 extra-European form to vi'hich the name of Upeneus has been given 

 by M. Cuvier, and vvhich is distinguished from the European Mullets 

 by the presence of teeth in the upper javv. Four of these fishes 

 appear to have been previously undescribed, and may be thus cha- 

 racterized :
