therefore no natural groups can be formed by using these 

 numeric characteristics. It appears also from the present 

 investigations as if the number of cotyledons was different 

 in the cornua uteri of the same specimen of some Antelopes, 

 but more material is needed to prove this to be a rule. 



If any taxonomic characteristics shall be obtained from 

 the cotyledons of the uterus, it seems more likely that the 

 number of rows will prove to be of more value for that 

 purpose than the number of cotyledons. 



Notes 011 the viseeral organs of some Cayicoriiia. 



Some years ago the present author (6) described the vi- 

 seeral anatomy of two species of Ceyhaloplius, viz C. ogilhyi 

 and C. melanorheus . Thanks to Dr. Trägårdh, I am now 

 able to add some notes about C. natalensis. All four por- 

 tions of the ruminant stomach are present. The preparate 

 being preserved in formalin it is not easy to ascertain the 

 exact dimensions but the paunch has a comparatively great 

 transversal expansion as in C. ogilhyi so that the breadth 

 across the fundus of both säcks (about 24 cm) appears to 

 be greater even than the distance from the cardia to the 

 end of the ventridextral säck (about 22 cm). Sulcus corona- 

 rius of the latter is well developed and defines a large saccus 

 ccecus which is triangulär in outline. The papillae are tongue- 

 like about 5 mm. long and often considerably narrower at 

 the base than at the rounded apex. The reticulum is rather 

 large with a longitudinal diameter of about 10 V2 cm., but the 

 'psalterium small measuring not quite 5V2 by VI2 cm. The 

 »cells» of the reticulum have mostly a diameter from 15 to 

 10 mm. and the stellate secondary sep ta are as a rule well 

 developed sometimes in such a degree that the »cells» are 

 completely subdivided, but the secondar}^ septa are always 

 recognizable being lower. 



The psalterium has just as in C. ogilhyi 9 large primary 

 septa armed with stout conical but sharply pointed papillae. 

 The broadest fold is about 15 mm. and the free lumen is 

 thus rather wide. Only in 3 or 4 of the lateral loculi there 

 are some faint indications of secondary septa.
