Show 1893.] DR. C. J. FORSYTH MAJOR ON A LEMUROID SKULL. 535 case in Hapal. simus too, and is obviously in relation to the downward bending of the facial portion. Owing to the incomplete condition of the fossil, only a few measurements can be given :- millim. Length of the fossil skull, from the occipital crest to anterior portion of frontals as far as preserved 92-7 Same distance in Hapalemur simus, Gray (Br. Mus. 1884/10. 20.4) 64-0 Greatest breadth of the brain-capsule between the two parieto-squamosal sutures, in the fossil 64*8 Ditto in Hapalemur simus 36*2 Fig. 3. Skull of fossil Lemuroid. Lower view, two-thirds nat. size. a, frontal sinuses ; b, cribriform plate. It thus appears that, whilst the fossil skull, in its part preserved, was about one-third longer than Hapal. simus, the breadth of its cranial capsule was almost double that of the last1. The foregoing short description gives all the important characters of this interesting fossil, which in my opinion clearly assign its systematic position to be within the subfamily of Lemurina?., and would besides justify the establishment of a new genus, having closer relation to Hapalemur than to any other members of the subfamily. I refrain, however, for the present, from giving a name to it, as there is some probability that more complete aud more adult specimens may before long come to hand. 1 The skull of Hapal. simus figured by Jentink (I. c.) is somewhat broader than the one at m y disposal.
