APPENDIX. 



During the passage of this volume through the press, a good 

 deal of additional material has come into the author's hands, 

 while the results of important recent explorations have also 

 been published. The following appendix has, therefore, been 

 added to include the latest additions to our knowledge of the 

 Anthropoids dealt with in its pages. 



On page S2, the Talapoin {Cercopithecus talapoin) has been 

 relegated to a group (and, indeed, it had been assigned 

 by Geoffrey to a distinct genus — Miopithecus\ in which it is 

 the sole example on account of the supposed peculiarity of 

 possessing but three tubercles on the posterior lower molar. A 

 specimen which the author has recently examined shows that this 

 character is not invariable, and the species should, therefore, 

 in his opinion, be transferred to among the Green Guenons — 

 Group II., Cercopitheci Chloronoti — and be placed next 

 after the Tantalus Guenon on page 62. 



The extremely important collections made by his friend 

 Dr. Forsyth Major during his adventurous explorations in 

 Madagascar in the years 1894 to 1896 — from which he has 

 but just returned — have made it necessary to add on page 212 

 a new family to the Anthropoidea. In the marshes of 

 Sirabe, in Central Madagascar, he discovered the fossil 

 remains of a species of true monkey— a group hitherto 

 unknown to occur in that island — which must have been 

 a contemporary of the ^pyornis, the well-known giant 

 moa-like ratite bird which once lived there, but is now 

 extinct. The fragments so far recovered show that in this 

 creature the orbits were directed straight forward and
