 The cartilaginous end of the free syringeal semi-ring corre-

Syrinx of the Jack Snipe (Limnocryptes (jallinulcc), ventral aspect, shewing 

 the peculiar form of the syringeal box, the intercalary bar, and 

 the accessory cartilage. Note the attacliment of the latter to the 

 intercalary bar by the bundle of short fibrous strands. 



B.t. = Broncho-trachealis muscle. 

 B.r.I, = First bronchial semi-ring. 

 F.r. = Fused rings forming the syringeal box. 

 S.f.s.r. = Semi-fused syringeal semi-ring or intercalary bar. 

 L.c. — Lingual cartilage or accessory cartilage. 

 F.l. = Fibrous ligament between the intercalary bar and the 

 accessory cartilage. 



forced apart from its normal attachment. Next it will be 

 noticed that the campanulate mouth is divided into right and 

 left moieties by a fibrous median partition forming a vertical 

 pillar across the end of the trachea at its junction with 

 the bronchi. This pillar answers to the "pessulus," and 

 supports a vestigial semi-lunar membrane.
