I. — Preliminary Notice on Fossil Monkeys from Madagascar. 

 By Dr. C. I. Forsyth Major, C.M.Z.S. 



DURING my excavations in the marshes of Sirabe (Vakinankaratra 

 District, Central Madagascar), my assistant, Mr. A. Robert, 

 came upon a small fragment of a right upper jaw of a mammal, 

 containing the two anterior true molars, which presented the well- 

 known pattern of the Old-World Cercopithecidae. The presence of 

 true monkeys, as contemporaries of the JEpyornis, in very recent 

 deposits, appeared to be such an extraordinary fact that I anxiously 

 looked forward for further and more conclusive evidence. This 

 fortunately has since been forthcoming, by the subsequent discovery 

 of more complete remains. Two of the most important pieces, viz. 

 the anterior part of a skull, broken off behind the nasals and the 

 molar series, and a left mandibular ramus, are here figured and 

 briefly described.
