ANATOMY OF THE TAKIN. 209 



shorter and less curved than in Ovibos ; it measures 50 mm. and 

 is only slightly arched. 



The cricoid is of the usual form ; the expanded posterior plate 

 is 60 mm. in depth and 55 mm. across. It presents a median 

 posterior keel nearly 10 mm. in height. Owing to the extension 

 of the anterior part of the thyroid the ring is very obliquely 

 sloped, the anterior part lying at a lower level than the lowest 

 part of the posterior part. (Text-fig. 1.) 



The arytenoids are massive, 85 mm. in total length. The free 

 apex is expanded into a thin, curved, and fenestrated plate. The 

 vocal process is a rounded knob-like eminence. The muscular 

 process is a long stout bar extending downwards and forwards 

 for 40 mm. from the body. It is thus only 5 mm. shorter than 

 the expanded free portion. (Text-fig. 2.)

The epiglottis is bluntly rounded at the apex, 50x35 mm. 

 in size. Only about one-half of it is free. The surface is pitted. 

 It is therefore similar to the epiglottis of the Gnu and Musk-ox. 



I'he tracheal rings ai-e irregulai'ly imbricate. Their joosterior 

 ends are separated by a distance of 30 mm. and there is thus no 

 posterior keel, in contrast to the trachea of Bos and Connochcetes. 

 Tliere are 15 rings above the eparterial bronchus and then 

 4 succeeding ones before the bifurcation. The absence of keel 

 gives the trachea of Budorcas a resemblance to that of Ovibos, 

 but there is no dorso-ventral flattening. The ends of the rings 

 in Budorcas project dorsally, whereas those of Ovibos appeal- to
