JACK SNIPE 
seemed to have been derived from the tracheal, not the bronchial series 
of rings, and which, so far as Mr Pycraft could make out, was met with 
in no other bird. He said that in the accompanying figure this semi -ring, 
for the sake of clearness, had been made to appear as if widely separated 
from the syrinx (fig. 1, S.-f.s.r.). The lower third of this peculiar semi- 
ring was cartilaginous, and was attached by a bundle of short fibrous 
threads to a Ungulate plate of cartilage, which in turn was attached to the 
inferior end of the first bronchial ring (fig. 1 , B.r.I.). What part this peculiar 
semi -ring and its accessory lingulate cartilage played in the production 
of the remarkable sounds which the jack snipe was known to produce, 
was a matter for further discovery. The identity of the first bronchial 
ring was established by the insertion of the intrinsic muscle, which was 
of the normal type. 
If the syrinx of the common snipe (fig. 2) were contrasted with that of 
the jack snipe on the one hand and that of the woodcock (fig. 3) on the other, 
it would be found to hold an intermediate position between the two, in so 
far as the expansion of the syringeal chamber was concerned; but the 
hindmost of the fused rings was v/ider than in either of the contrasted 
forms, and was produced further backw'ards, giving a more pronounced 
V -shape to this end of the trachea. The intercalary syringeal semi -ring 
(fig. 1, S.-f.s.r.) and its accessory plate of cartilage were wanting.
