on Mr. G. R. Gray’s ‘ Genera of Birds.’ 417 
ear like Oius, and cites two species, U. lapponica and U. nebulosa. 
But it appears that the U. lapponica has not a large ear-cavity, but 
agrees in its structure with the genus Syrnium, so that the nebulosa 
only can be quoted as a type of Ulula, Cuv. This error of Cuvier’s 
was pointed out by Bonaparte in his excellent but little-known 
‘ Osservazioni sulla 2% edizione del Regno Animale del Barone 
Cuvier,’ Svo, Bologna, 1830, p. 43. Bonaparte retains the specific 
name cinereum, Gm., as being prior to lapponicum, Retz. 
The specific name Nyctale tengmalmi (Gm.)* should be used as 
being prior to dasypus, Bechst. 
P. 8. Does not Collocalia, Gray, belong to the Hirundinine rather 
than the Cypseline ? 
P. 9. The subfamily Coraciane ought, I conceive, to be included 
in the Halcyonide ( Alcedinide, mihi,) rather than among the Todide. 
The structure of their feet, their habits, and the ccerulean tints of 
their plumage, show great affinity, first to the Bee-eaters and through 
them to the Kingfishers. (See my ‘Map of the Alcedinide,’ Ann. 
Nat. Hist. vol. vi. pl. 8.) ‘They may, however, lead towards the 
Todide in the other direction, as there shown. 
The genus Corydon, Less., 1828, though afterwards united by 
Lesson to Hurylaimus, forms a very distinct generic type, and should 
take its place as follows :— 
Corypon, Less., 1828, < Coracias, Raff., < Eurylaimus, Tem. 
C. sumatranus ( Raff.) n. E. corydon, Tem. Pl. Col. 297, C. tem- 
minckii, Less. 
The Momotine are evidently only the American group of the Bee- 
eaters, and might, I think, be included with them as a mere sub- 
family, Meropine, of the Halcyonide. 
The Prionites mexicanus, Swains., is not the same as Crypticus 
platyrhynchus, but is a true Momotus, figured by Jardine and Selby 
(ill. Orn. ser. 1. pl. 25.), where it is erroneously named M. martiz. 
The true marti of Spix is said by Bonaparte to be the same as Cryp- 
_ ticus opealiae which in that case should be called C. martii 
Spix). 
‘ P. 10. Calurus resplendens was named paradiseus by Bonaparte in 
1826. (See Proc. Zool. Soc. part v. p. 101.) 
There seems to be no sufficient ground for including the Tama- 
tiane among the Halcyonide. ‘This group possesses structural cha- 
racters which entitle it to rank as a distinct family under the name 
of Capitonide. 
_ Mr. Gray transposes the names Tamatia and Capito as used by 
Mr. Swainson, a step which would certainly cause confusion, but 
which may be rectified as follows. It should first be observed, that 
when two authors give separate names to precisely the same group, 
the later name should be cancelled in toto, and not allowed to share 
* I have found great convenience in always writing specific names with 
a small initial letter, even when they are derived from persons or places. 
The eye thus at once distinguishes specific from generic names, and avoids 
the confusion caused by specific names commencing occasionally with a 
capital letter like genera.
