{286}ADULT.--Head and neck black. Face, snout, and ears naked, and of a blackish colour, encircled by a broad band of long white hairs, joining under the throat, slightly mixed with darker hairs. Rest of fur, including the tail, white on the upper surface; back and upper rump dark brown. The large white patch on and between the shoulders much grizzled with brown hairs. Under side of hind-limbs, to just below the knees, blackish-brown. Inside of hind-limbs down to the heel also brown, joining the colour of the upper surface, thus forming a continuous dark stripe along the legs. Inner and upper surface of arms, thumb, and two following fingers, deep blackish-brown; throat, chest, and greater part of abdomen, deep brown. Size perceptibly larger than that of _Propithecus verreauxi_, with the tail longer. This species of _Propithecus_ is nearest to the typical _P. verreauxi_ of Grandidier, which is white, with the top of the head black, and the lower back and rump greyish-brown, but is no doubt an entirely different species.

"The 'Naturalist's Library' has all the signs of earning and keeping a wide popularity."--_Scotsman._ "They are carefully compiled from the most authentic sources of information, and are embellished with cleverly-executed coloured plates."--_Daily News._ "Admirable in every way, and should be highly popular."--_Public Opinion._ "Really good handbooks, well arranged, concise, carefully printed, and handsomely illustrated with full-page coloured plates."--_Science Gossip._ "Eminently readable, the information being given in an interesting manner."--_Field._ "A most valuable feature of these volumes is the plates, which have been coloured from specimens in the British Museum, and are by far the finest that have ever appeared in any work at the price, or anything near it. Altogether the character and general get-up of 'Allen's Naturalist's Library' leave nothing to be desired. We trust these volumes, and those that may come after them, will be widely welcomed."--_Westminster Gazette._ "Should prove most instructive to every student of natural history."--_Rod and Gun._ "Abounds in interesting matter, and can be read through with pleasure."--_Saturday Review._ "May be heartily recommended."--_St. James's Budget._ LONDON: W.
