APPENDIX. 
No. 4. — Mr. A. Wallace obtained adult males of SImia Morio (vide 
Zoologist, p. 5113, Ann. M. N. II. xvij (1856), p. 473. 
No. 6. a. — H. agilis, F. Cuvier. Two specimens presented by the Maha- 
raja of Burdwan. 
No. 9 & 11 . — A newly born hybrid, from a Cape Baboon by a Pig-tailed 
Monkey, was presented to the Museum by Babu Rajendra 
Mullika in 1862. 
No. 13 & 14. — I now consider these to be identical, varieties merely, 
such as are noticed by Raffles of his S. carpolegus. The 
species inhabits so far as the rocky hills bordering Akyab 
Harbour to the south. I doubt, however, whether Macacus 
arctoides of Lesson, is rightly placed here as a synonym. 
No. 17 & 18, — Are scarcely more than varieties of the same Monkey, 
with or without a slight top-knot on the vertex. 
No. 52. — Doubtless Pt. nicobaricus, Scherzer. 
No. 58. a. — Add Cynopterus nicobaricus, (?) Scherzer. From Andamans, 
Col. Tytler. 
No. 95. — Vesp. formosa, Hodgson, is evidently identical with my Tickelli, 
Vide Fig. P. Z. S. 1858, pi. xv. 
No. 175. — I don't think this name can stand. It is Macrocelis.
