EINAR LÖNNBERG. ANATOMY OF THE RUMINANTS.

Antilocapra, for instance with regard to the structure of the 

 psalterium with its uncommonly blunt papillse, the great 

 number of colic coils and so on. This resemblance must be 

 regarded as a result of an adaptation to a similar mode 

 of iife and a similar coarse diet. This is the more convin- 

 cing as other ruminants whieh, like those mentioned, to great 

 extent have to subsist on a coarse diet, as for instance 

 Ovihos (5), show the same characteristics blunt papillaB in 

 the psalterium and many colic coils. 



The intestinal canal Capra 

 falconeri, kindly put to my dispo- 

 sition by Prof. Dr. L. Heck, of- 

 fers same interesting features 

 which deserve to be described. 

 The paunch appears to be com- 

 paratively simple. In addition to 

 the main division in a dorsi-sinist- 

 ral and a ventri-dextral säck there 

 seems to be but one subdivi- 

 sion viz. a saccus ccecus formed 

 by a sulcus coronarius on the 

 right säck. The papillse of the 

 ymunch of this animal differ a 

 great deal from the usual tongue- 

 like type. The general shape is 

 rather cylindrical, although often 

 irregular. Sometimes two (more 

 seldom three) papillse appear to 



have been fused together but Fig. 8. Papiiia3 of the paunch of

_^ • 'i r J.T, Ml 1 papillaB seen from the side- 



majority of the papillse have ^ ^ 



their ends more or less covered 



with irregular wart-like excrescences, and by this arrangement 



they get an appearance which reminds one about some al- 



cyonarian corals. For the mechanical functions of the paunch 



this kind of papillse, no doubt, is more suitable than the 



common tongue-like type. 



The structure of the reticuhcm is also a great deal aber- 

 rant from the common type. The »cells» are small and the 

 septa are comparatively very high about 4 mm., and thick- 

 w^alled about IV2 mm. When the reticulum is empty and
