THE SPORTIVE-LEMURS. 85 
larged and swollen, in this respect differing from the skulls of 
Lemur and Hapalemur. The ridges in the temporal bone 
unite into a frontal (sagittal) ridge, and the space between the 
orbits is depressed ; a depression is also present on the cheek in 
front of the lachrymal foramen. The foot is slightly elongated 
by the lengthening of the zavicwZare bone of the ankle (Zarsus), | 
the thin bones of which are short. In the wrist (carpus) there | 
is no os centrale or central bone, which is otherwise invariably 
present in the Primates, except in Man, the Chimpanzees, the 
-Gentle-Lemurs, and the Endrina. 
The Sportive-Lemurs are confined to Madagascar and 
are nocturnal and arboreal creatures, feeding on leaves and 
fruits. 
In Group A (the larger species) are included: 1, The Weasel- 
like Lemur (Z. mustelinus) ; 2, the Red-tailed Sportive-Lemur 
(ZL. rujficaudatus) ; 3, Edwards’ Sportive-Lemur (Z. edwardst) ; 
and 4, the Small-toothed Sportive-Lemur (Z. microdon). Group 
B (consisting of the smaller species) comprises: 1, The 
Round-headed Sportive-Lemur (Z. gdobiceps); 2, Grandi- 
dier’s Sportive-Lemur (ZL. gvandidieri); and 3, the White- 
footed Sportive-Lemur (Z. leucopus). With the exception 
of the two first-named species, all the others are here 
made known for the first time by Dr. Forsyth Major. Very 
little is recorded of the habits of these animals. ‘They are so 
rare that at present the various species are known from a 
few skins or alcoholic specimens in European museums, 
They are said to be inhabitants only of the forest-country, 
nocturnal in their habits, sleeping coiled up in some retreat 
all day, but issuing forth at night, at which time they are very 
agile in their movements.
