1/6 SIR R. OWEN ON THE GENUS DINORNIS. [Mar. 18, 



March 18, 1884. 

 Prof. W. H. Flower, LL.D., F.R.S., President, in the Chair. 



The Secretary read the following report on the additions to the 

 Society's Menagerie during February 1884 : — 



The total number of registered additions to the Society's Mena- 

 gerie during the month of February was 102, of which 13 were by 

 birth, 51 by presentation, 27 by purchase, 3 received in exchange, 

 and 8 received on deposit. The total number of departures during 

 the same period, by death and removals, was 98. 



The most noticeable additions during the month were: — 



1. A young specimen of the Red-eared Monkey (Cercopithecus 

 erythrotis), purchased February 14. 



This Cercopithecus was originally described by Mr. Waterhouse 

 in our ' Proceedings ' for 1838, from an imperfect skin, and wa3 

 subsequently figured by Fraser in his ' Zoologia Typica' (plate iv.). 



The species is new to the collection, and the present individual is 

 the first that I have seen of it. It is said to be from Fernando Po. 



2. A fine female example of what appears to be Martin's Mon- 

 key (Cercopithecus martini), also from Fernando Po, purchased 

 February 19. 



This species, a close ally of the Lesser White-nosed Monkey 

 (Cercopithecus petaurista), was originally described in our 'Pro- 

 ceedings' by Mr. Waterhouse as long ago as 1838, from two skins 

 (see P. Z. S. 1838, p. 58), and named after Mr. W. L. Martin, 

 author of the well-known volume on 'Man and Monkeys.' I 

 exhibit a coloured drawing of it by Mr. Smit (Plate XIV.). It 

 will be observed that it is at once distinguishable from C. petaurista 

 by the black fore limbs and feet, by the absence of any red colour 

 on the tail, by the greenish-grey and not white sides of the face, 

 and by the different form of the white nose. As our specimen is a 

 female, I presume that C. martini is also a larger animal. Our 

 specimen of the latter measures, the body about 19 inches, the tail 

 about 24, together 43 inches. 



3. An example of a rare Ichneumon from Ceylon, MacCarthy's 

 Ichneumon (Herpestes maccarthice), new to the collection, pur- 

 chased February 23. 



Mr. Tegetmeier, F.Z.S., exhibited some specimens illustrative of 

 the variations of colouring in the feet of the Pink-footed Goose 

 (Anser brachyrhynchus) . 



Sir Richard Owen, K.C.B., F.R.S., read the twenty-fifth of his 

 series of Memoirs on the extinct birds of the genus Dinornis and 

 their allies. The present Memoir contained a description of the 

 sternum of Dinornis elephantopus, which had been obtained at 

 Christchurch, New Zealand. 



This Memoir will be printed entire in the Society's 'Transactions.' 



The following papers were read : —
