Davidson says that Hagenow added a false beak to some 



of his specimens of T. costaia, which seems to be a Trigo- 



nosemus. Woodward mentions the same thing, and adds 



that a cast of this false beak is in the British Museum. 



/ Dalman quotes T. lyra, Sow., in his synonymy of T. costata, 

 but places a note of interrogation after the "rostrum .... 

 producta?" in his diagnosis. The name would seem to be 

 well retained as a subgenus of Magas, with the second species 

 as the type.
