papilloe, which increased in size and length, but diminished in num- 

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

 rima glottidis long; and from the arytenoid cartilages two 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 

 Curassovo, (Ourax Mitu, Cuv.,)was laid on the table, and Mr. Yar- 

 rell pointed out the peculiarities of its very elongated trachea, which 

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

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

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

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

 that this disposition prevails, 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 which the prolongation of the ^rac/iea 

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

 fcrus and Cygn. Beivickii,) the sternotracheal muscles pass from 

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

 and are not continued along the fold o? trachea included within the 

 bone. 



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

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

 nett called the attention of the Committee to the species o^ Mullet 

 contained in it. These were eight in nun)ber, and belonged to the 

 extra-European form to which the name of Upeneus has been given 

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

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

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

 racterized :

 vornerem, et ossa palatina : capite pone oculos subdepresso : jjin- 

 nis dorsalibus caudalique nigro oblique Jcisciat is ; corpore toto
