TRACHEA OF THE GALLING.

at one end, and the other (as does the second in Euplocamus) with the 

 first. Ceriornis satyra agrees exactly with C. temmincki in its 

 lower larynx.

My acquaintance with the trachea of Francolinus is confined to 

 F. vulgaris, an early sketch, too, only of that. Its great peculiarity 

 is that the first three bronchial semirings articulate together, the 

 third being decidedly the strongest, the first and second being 

 separated by a greater interval than exists in Ceriornis. 



In Crossoptilon mantchuriciim the thoracic end of the trachea is 

 euplocamine in construction. It narrows considerably near its 

 termination, at which it again expands. The only indications of 

 interannular intervals are small medio-anterior fusiform spaces, absent 

 between the antepenultimate and penultimate rings, and replaced by 

 a fusion in the case of the last two, on each side of which the lateral 

 separation between the rings expands into a minute triangular in- 

 terval, smaller than in Euplocamus. The pessulus agrees with that 

 of the Euplocami. The interval between the last tracheal ring and 

 the first bronchial semiring is very large, both upper and lower 

 margin being about equally convex upwards, from the shape of the 

 last tracheal ring and the uptilting of the first semiring. The in- 

 terval between the first and second semirings is scarcely smaller, 

 and is ovoid, the latter semiring being decidedly downturned 

 laterally, bent upwards abruptly near its ends, and particularly 

 strong throughout. On the whole, the organ is more like that of 

 Phasianus than Euplocamus, its most striking difference from the 

 former being the lateral uptilting of the first bronchial semiring, 

 and the similar tendency in the sides of the last tracheal ring. 



In Lophophorus impeyanus the lower tracheal rings, which are 

 narrower than those above, are in contact with one another behind ;
