He was very fat and much the largest example of this species I have ever seen. He was not only remarkable for his immense size, but for his partiality for standing and walking erect and the intelligent manner in which he used his tail to assist him in that position; at times he supported himself by it somewhat after the manner of a Kangaroo, and at others clung to an iron bar by it and so helped to keep an equilibrium. " I attribute the fact of such a delicate monkey having lived for many years in confinement so far north of his regular habitat, on the upper waters of the Amazon, Rio Negro, and Orinoco rivers, to the extreme equability of the climate on the seaboard of Mexico and to his spending every day in the open air." Dr. Walter Kidd, F.Z.S., read the following note on the arrangement of the hair on the nasal region of the Parti-coloured Bear (jEluropus melanoleucus):- " In the memoir of Professor Lankester, published last year in the ' Transactions' of the Linnean Society, on the Affinities of sEluropus melanoleucus, no reference is made to the mode of arrangement of the hair on the nasal region. This is of the Derivative type (sketched on blackboard), in which respect ^Eluropus differs from all the Ursidse as well as from Procyon, And in which it resembles the Felidse. It can hardly be claimed that a character so superficial and intrinsically unimportant as this can contradict the veiw of the affinities of this creature, which are based on the more stable osteological and dental characters. If it be not a character indicating affinity, this arrangement of the nasal hair-stream may be held to have arisen in one of two ways-either by being simply correlated with the broad zygomatic region of JEluropits, or as the result of some habit peculiar to it. Whatever the explanation may be, the fact seems to be worth recording." Mr. R. E. Holding exhibited and made remarks upon the double head of a Dorset Lamb. The heads were of unequal development and united from the orbit to the base of the skulls. In the longer head the palate was cleft along its entire length, the lower jaw having a complete set of deciduous incisors. The smaller head had also the palate completely cleft and a small opening in place of the mouth; there was no trace of either tongue or lower jaw. The upper or dorsal aspect of the 25* |
