known as the King Monkey, but is rare. This form of the Patas, of 

 which we have now two living specimens, nearly resembles the Nisnas 

 Monkey (C. pyrrhonotus) except in having a black nose. It seems 

 to me quite distinct from the smaller form, which we generally receive 

 as the Patas, and requires further examination. 



3. Three Night-Parrots (Stringops habroptilus) , purchased No- 

 vember 3rd. Two of these appear to be a pair, agree well together, 

 and appear likely to do well ; the third, I regret to say, we have 

 already lost. 



4. A male Muutjac {Cervulus), purchased November 6th of the 

 Jardin d'Acclimatation, Paris. This animal is from the French 

 colony of Saigon, and appears to show that the form inhabiting 

 this district is nearly allied to the true C. muntjac. I propose to 

 speak of it more fully in some notes which I have now in prepara- 

 tion upon the Cervuli living in the Society's Gardens. 



5. Eighteen Lancelets (Amphio.vus lanceolatus), presented Nov. 

 14th by the Directors of the Zoological Station, Naples, being the 

 first examples of this " invertebrate vertebrate " that have yet reached 

 the Society's Fish-house. 



6. A pair of Muntjacs (.Cervulus, sp. inc.), from Formosa, pre- 

 sented by Mr. W. P. Galton, November 17th. Of these I shall 

 speak more fully in the paper mentioned above which I have in pre- 

 paration. 



7. Two Agoutis from St. Lucia, West Indies, presented by Mr. 

 Neville Holland, November 24th. 



In August 1868 we received from Mr. G. H. Hawtayne, of St. 

 Vincent, West Indies, a pair of Agoutis which are referred, in the 

 •Revised List of Vertebrates ' (p. 76), to the Acouchy {Dasyprocta 

 acouchy). The present animals from St. Lucia are evidently of the 

 same species, as I find by comparing them with one of the St. -Vin- 

 cent specimens, which has been preserved for examination. But they 

 are certainly not referable to D. acouchy, to which I must have re- 

 ferred the first specimen, simply because Mr. Waterhouse says that 

 that is the species found in the West-India Islands*. They belong, 

 on the contrary, to the short and naked-tailed group of Dasyprocta 

 allied to D. aguti, and seem most like D. punctata of Central 

 America f, but are smaller in size and much darker in colour. The 

 fur is generally black minutely grizzled with yellow ; but the crest 

 at the back of the head and long hair on the hinder part of the back 

 are of a nearly uniform black. 



The total length of the body in the specimen from St. Vincent is 

 about 14 inches. 



Dr. Gray has described a Dasyprocta albida from St. Vincent, 

 concerning which it is sufficient to refer to Mr. Waterhouse's observa- 

 tions (Mamm. ii. p. 397). Even if this name could be shown to have

t Gray, Ann. N. H. x. p. 264 (1862), et Zool. Sulphur, pi. 15. Mr. Water- 

 house unites this to the Brazilian D. 'azarm ; but I am not sure that this is cor- 

 rect. We have hitherto referred the examples of this form received from Cen- 

 tral America to D. cristata ; but this is certainly erroneous.
