 Any one who examines the Coal Titmouse figured in P^nglish 

 works, and compares it with the figure given in any Conti-

On a new Sperir.-f of Buceros. By O. R. Gray. 



[Plate XVIL] 



Having had ray attention dra^^Ti by Mr. E. Bartlett to a head and 

 bill of a species of Buciros which, on examination, presented in its 

 formation very remarkable differences from any of the known spe- 

 cies of that group of birds, I am induced to offer the following 

 description of its singidar and distinctive characters, under the 

 name of 



Buceros {Bjjanixtes?) casuarinus. PI. XTII. 



Bill broad at base, laterally compressed to the tip ; casque ele- 

 vated posteriorly and extending somewhat backwards over the eyes, 

 rather compressed along the cnlmen, which is fiat and grooved 

 along the middle for two thirds of its length, the sides of the 

 casque shelving to the nasal channel, and furnished with six 

 deep oblique grooves ; the sides below the former are comjjaratively 

 smooth, and with three apparent scales near the eyes ; the nos- 

 trils are large and deeply imbedded in a broad channel which runs 

 along the sides of the maxilla for about two thirds of its length, in 

 which they are situated at its base ; the mandibula has the gonys 

 long and curved to the tip : the sides are furnished with four very 

 obliquely placed grooves, advancing towards each other beneath
