tlnis the necessity for a prolongation of the musele further 

 than this point disappears. I have mentioned above that 

 the terminal " box " of the trachea is sometimes composed of 

 a larger number of elements than is allowed by Garrod. This 

 opinion results from the study of a young chick^ in which 

 the last tracheal rings are free^ and the syrinx (see fig. 4) has 

 altogether a more " typical ^' structure than that of the 

 adult. The muscle is seen to terminate on the Hth ring 

 before the first bronchial. This appears to show that the 

 tracheal box is formed by tiie fusion of eight tracheal and 

 bronchial rings ; the syringeal muscle in the chick is con- 

 tinued into a fibrous band (fig. 4 b), the relations of which 

 are similar to those of the adult. 



XXVII. — N^ote on Emberiza cioides, Brandt. 

 By H. B. Tristram, D.D., F.E.S. 



(Plate X.) 



Attention has lately been drawn to the Eastern PalaEarctic 

 Bunting, Emberiza cioides, Brandt, Bull. Acad. Sci. St. Pet. i. 

 p. 363 (1843), by the fact that our Member, Mr. R, W. Chase, 

 of Birmingham, has lately obtained at Flamborough a spe- 

 cimen of this sjaecics. This specimen is stated to have been 

 taken there in October 1887, and to have been mounted fi'om 

 the flesh by Matthew Bailey, who did not know the bird, and 

 Avas quite ignorant of the interest attaching to it. The species 

 has considerable seasonal variation, and this specimen agrees 

 exactly with one in my own collection obtained near Lake 

 Baikal in the month of October. So far, therefore, the 

 evidence of its occurrence at Flamborough seems satisfactory. 

 But it is curious that the bird has never been met with 

 before in Europe, not even in that resort of unwonted 

 stragglers, Heligoland, nor even in Western Siberia. 



The confusion in the nomenclature of this Bunting is 

 almost inextricable. First noticed by Pallas, it was by him 

 crroncouslv identified with Emberiza cia, L. It is evident
