1835.] Note on the Red-billed Erolia. 701 



remote, erect, spheroidal : auricle of the same form, and directed 

 towards the conch of ear ; posterior margin of the helix folded out- 

 wards, and carried forwards to the gape. 



Saturate brown throughout. Skin, wherever denuded, purpure- 

 scent. Teeth -^ — ~ x ~ ; snout to rump, three inches ; tail, two ; 

 expanse 15. 



Remarks. — The bats remain with us throughout the year, and do 

 not hibernate. They quest for food solitarily, and therein chiefly 

 their manners differ from those of the Rhinolphi. Labiata is closely 

 affined to M. Geoffroy's Noctula, and has a very different physiog- 

 nomy from the other two species, which have both a sharp visage, 

 though their crania exhibit in the facial part a considerable diversity, 

 In Formosa, the nasal bones are slightly convexed in their length, 

 and unite easily with a low forehead : in Fuliginosa, the same bones 

 incline to a concave bend in their length, and join a high forehead, 

 with a considerable curve. 



IX. — Note on the Red-billed Erolia. By the same. 



With reference to the paper on the Red-billed Erolia, published in 

 your No. for August, I beg to acquaint you that I have been induced 

 to adopt a new genus for this bird, and that the change of the generic 

 has led me to the alteration of the specific name also. As I am 

 no friend to the multiplication of names, I would observe, that in 

 adopting a new genus, I have been governed by these two circum- 

 stances — 1st, that Viellot's genus Erolia has been rejected ; 2nd, 

 that Gould's genus Ibidorhyncha is inaccurate. I have had opportu- 

 nity to examine three specimens, and from careful comparison of 

 them, have drawn the following generic character. 



Genus Clorhynchus. 



Rostrum omnino Numeniacum : differt tamen tomiis inflexis denti- 

 culatisque, necnon apicibus acutiusculis. 



Corporis, alarum caudaeque forma sicut in Grallatoribus typicis. 



Tibiae et tarsi sub-breves, tibiae trans medium plumosae, teres : tarsi 

 leviter reticulati. 



Pedes tridactyli typice cursorii, marginibus tamen digitorum subdi- 

 latatis, externoque digito libero. 



Species nova. CI. Strophiatus, Anglice Gorgeted Clorhynx. 



CI. corpore supra, colloque plumbeis. Cauda, pallidiore.fasciisque ni- 

 gris transversim instructa. Corpore subtus albo. Capitis vertice, facie, 

 guttureque nigris. Pectore strophio nigro ornato. Iridibus rostroque 

 sanguineis. Pedibus purpurescente griseis.
