776 MESSRS. O. THOMAS AND B. C. WROUGHTOX OX [ISToV. 12,. 



"The scarcity of mammals, especially the smaller ones, is probably 

 due to the annual flooding of the country, as numbers must be 

 drowned out and killed during the rainy season." 



1. Oercopithecus pygerythrus Cuv. 



c?. 1743, 1746, 1794. $ . 1744, 1745, 1793. Beira. 



It is worthy of record that no. 1746, a mere baby in arms, the 

 son of no. 1744 {teste the Collector) has, above the usual white 

 brow-streak, a sandy-coloured streak separated from the former 

 by an indefinite black one ; this eftect is produced by the fact that 

 the hairs immediately above the white face- streak are black Avith 

 yellow tips. 



" Native name, ' Shoku.' 



" Fairly common in all the forest and seen in troojos of from 

 six to perhaps a dozen or fifteen. 



" Extremely wary and at the least sign of danger hiding in the 

 tops of the trees and on the upper sides of the larger branches, 

 where it is impossible to detect them ; they can sometimes be 

 secured by lying in wait where a troop has been seen to thus 

 disappear. 



" Diurnal only, and living on the wild fruits and berries." 



2. Oercopithecus albogularis beirensis Poc. 



P. Z. S. 1907, p. 701. 



c?. 1761, 1781. Beira. 



A new form described by Mr. B. I. Pocock on these specimens, 

 and therefore to be credited as one of the discoveries of the Budd 

 Expedition. No. 1761 is the type. 



3. Galago granti Thos. & Wrought. 

 $ . 1695, 1696. Beira. 



Both specimens are quite young. 

 " Native name, ' Sfenge.' 

 " Apparently not common. 



" Frequenting the forests and breeding and sleeping in the 

 hollow trees." 



4. Epomophorus crypturus Pet. 



J. 1685, 1686. $.1687. Masembeti. 



These specimens undoubtedly represent the E. crypturus' oi 

 Peters, the type locality of which was Tette. Whether this name 

 is a synonym of E. gambianus as stated by Dobson, may be left 

 to be decided when the genus is again thoroughly overhauled. 



" Native name, ' Igoshe.' 



" Observed only in the bed of the Masembeti B., where thes& 

 specimens were disturbed from the overhanging ti'ees, and shot. 



" According to the natives it is common, and is constantly seen, 

 by them when the ' cachou ' trees are in fruit."
