350 THE SECRETARY ON ADDITIONS TO THE MENAaBRIB. [DeC, 2, 



here considered. There are several, however, by which it appears 

 to be even more ge^iei^cdized than Palceotragus ; namely, the narrow 

 frontal region with its non-telescopic orbits, the anterior position 

 of the lattei', the smaller size of the homs, and the more brachyo- 

 dont condition of the cheek-teeth (as compared with the large 

 fossil species Samotherium boissieri). In one feature only, the 

 large extension of the air-sinuses in the bony palate, the Okapi 

 has conversely progi-essed further than the Giraffe. 



PalceotragiLS, finally, is more generalized than the Okapi — and, 

 as a matter of course, more so than the Giraffe — in the non-fusion 

 of the five tarsal bones into one, in the comparatively very slight 

 extension of cranial air-sinuses, and in the anterior position of 

 the horns. 



To swm up the state of our present knowledge of the Okapi. — In 

 the species preserved at Tervueren {Okapia liebrechtsi) the male 

 is provided with horns, but the same will presumably prove to 

 be the case in the species represented in the Natural History 

 Museum also. 



The mode of formation of the horns of the Okapi is the same 

 as in the Girafie. In the present state of our knowledge they are 

 limited to the male alone of the former, so that the Okapi is in 

 this respect on the same level as Palceotragus, the Giraffe having 

 progressed farther. 



Besides the last- mentioned some further features which the 

 Okapi shares with Palceotragus, and all of them of a more gene- 

 ralized character as compared with the Girafie, have been added 

 to those formerly pointed out. 



One feature has been added to those formerly mentioned, in 

 which the Okapi occupies an intermediate position between Pcdceo- 

 tragus and the Gii'affe. 



And, lastly, we have been able to adduce some characters 

 in which the Okapi appears to be even moi'e generalized than 

 Palceot7'agics. It is this last category especially which adds 

 weight to the assumption that Africa was the original home of 

 the Giraffidae. 



December 2, 1902. 

 Dr. Henry Woodward, F.R.S., Yice- President, in the Chair. 



The Secretary read the following report on the ajlditions to the 

 Society's Menagerie during the month of November 1902 : — 



The registered additions to the Society's Menagerie during the 

 month of November 1902 were 68 in number. Of these 41 were 

 acquired by presentation and 1 by purchase, 1 was born in the 

 Gardens, 21 were received on deposit and 4 in exchange. The 

 total number of departures during the same period, by death and 

 removals, was 115. 



Amongst the additions special attention may be called to a fine
