[Apr. I, 



the first semirings articulate by their equally lengthy extensions 

 inwards beyond the short articular processes for the second semi- 

 rings. The posterior articulations of the incomplete last tracheal 

 ring with the first semiring, and of that with the second on each 

 side, are considerable, and much the same in detail as in Caccabis. 

 The pessulus blends with the penultimate ring behind. The lateral 

 intervals between the penultimate and last rings are plano-convex, 

 the plane side being uppermost ; those between the last ring and 

 the first bronchial semirings are meniscoid, very deep, and con- 

 cave upwards. Between the first and second semiring the interval 

 is small, elongate, and curved like the one above it.

Coturnix communis. 



Ftilopachys ventralis differs very little from Coturnix in this part 

 of its windpipe. 



Rollulus coronatus closely resembles the Oxtyxes and Quails. 

 There are five fairly deep antero-lateral interannular intervals between 

 the lowermost six tracheal rings, these same rings meeting in the 

 middle line in front as well as through all the posterior moiety of 

 the circumference. Ossification extends through the median fused 

 anterior portions of the penultimate and last tracheal rings, as well
