nest. On the 18th of August one young was hatched, which the 

 parent bird immediately proceeded to eat. The other egg (ex- 

 hibited herewith) was addled. The period of incubation was 

 exactly 28 days. The only observable difference between the male 

 and female Cariama is that the female is rather the largest." 



lu reference to their communication on the Dentition of the 

 Manatee S Messrs. Thomas and Lydekker desired to draw attention 

 to a memoir on the same subject by Dr. Clemens Hartlaub, pub- 

 lished in 18S6 ''. This paper, mainly on account of its title, had 

 been overlooked, the references in the ' Zoological Record ' being so 

 worded as to make it appear that it referred chiefly or entirely to 

 the distinction and geographical distribution of the species, rather 

 than to any more general question. 



So far as the number of teeth in the Manatee was concerned, 

 Dr. Hartlaub had come to very much the same conclusions as 

 Messrs. Thomas and Lydekker, and on nearly similar grounds, but 

 he had ventured to go even further in the estimate of the number 

 of molars which it might be possible for the animal to develop in 

 the course of its life. 



Since this part of Dr. Hartlaub's admirable paper had, at least 

 in England, by no means attracted the attention it deserved, the 

 present authors, while regretting the omission of reference and 

 credit to Dr. Hartlaub, felt at the same time it was no disadvantage 

 to science that the wonderful dentition of the Manatee had been 

 described afresh in a publication so widely read and quoted as the 

 Society's 'Proceedings.' They would likewise take the opportunity 

 of expressing their gratification that the conclusions reached by 

 themselves, startling and improbable as these at first sight seemed, 

 had been independently attained by so competent a judge as 

 Dr. Hartlaub. 



Some of the palseoutological points advanced by the present 

 authors, and the bearing that a knowledge of the Manatee's den- 

 tition would have on the homologies of other Mammalian teeth, had 

 not been discussed in Dr. Hartlaub's paper. 



Mr. Lydekker exhibited on behalf of the Hon. A. E. Gathorue- 

 Hardy a flat skin of Ursus pruinosus, collected by Mr. Keil Malcolm 

 in Tibet. Although differing considerably in coloration from the 

 specimen figured in plate xxvii. of the present volume (P. Z. S. 1897, 

 p. 412) of the Society's 'Proceedings,' there could be no doubt 

 that the new specimen belonged to the same species — this being 

 especially shown by the bases of all the hairs being black. Much 

 less white on the head and shoulders was exhibited by the new 

 specimen, in which the ears were black instead of white. There was 

 also a rufous band down the middle of the back, not observable in
