p. 176, te.\t-tig. 3 (palate-ridges) (1892; Pungo Audongo). 



Diagnosis. — Similar to 21. leavhi, but with larger skull, broader 

 rostrum, broader frontal region, and heavier teeth ; palate-ridges 

 normally 4-f-4-f-l. Forearm 88-99 mm. 



Skull (fig. 2, on p. 17). — Similar to that of li. leachi, but larger 

 (see measurements, p. 34), and with markedly deeper and broader 

 rostrum. Premaxillaries often co-ossified. Frontal region between 

 orbits comparatively very broad, the width of the interorbital con- 

 striction in fully adult specimens distinctly larger than the width of 

 the postorbital constriction. Owing to a stronger development of 

 the temporal muscle (heavier cheek-teeth), the temporal crests unite 

 into a sagittal crest at a short distance behind the postorbital 

 processes, a sagittal crest being always developed in mature age 

 and often present even in individuals with almost unworn teeth. 

 For the same reason the coronoid process of the mandible is higher, 

 the angular portion stronger and more projecting. 



Teeth (fig. 2, on p. 17). — As in IL leachi, but averaging markedly 

 larger. 



Palate-n'Jr/es. — 4-(-4-t-l, i.e. essentially as in Ii. leachi, but 

 with an additional middle (divided) ridge behind the molars; the 

 formula given here is taken from a few alcoholic specimens only ; 

 some slight individual variation may be found. 



External characters. — General size averaging a trifle larger than 

 that of Ii. leachi, head proportionally much larger, muzzle deeper 

 and broader, ears larger, but precisely of the same shape as in 

 a. leachi; wing-structure as in H. leachi; upperside of tibia and 

 foot, to the claws, more densely haired. 



Colour rather similar to that of It. leachi, but of a somewhat 

 lighter shade. Back and rump hair-brown, with a slight tinge of 

 brownish slate ; crown of head and occiput darker than back ; 

 nape of neck light hair-brown, or drab. Underside grizzled smoky 

 grey ; foreneck and flanks in adult specimens often more or less 

 suSused with wood-brown. In dried specimens exposed to light 

 the slaty tinge of the upperside very soon disappears, the colour 

 fading into brown or yellowish brown. 



Measurements. On p. 34. 



lian(je. From Loanda and Gaboon to Egypt, Erythrea, Syria, 

 Palestine, and Cyprus. 



Tjipe in the Paris Museum. 



Fterojnis agyptiacus, Geoff. ; 1810. — Type locality : " la basse 

 Egypte " (" le plafond d'une dcs chambres de la grande Pyramide ''). 

 Based by Geoffrey on " plusieurs individus '* ; of these one onlj- 

 ajipears now to be in the Paris Museum, an adult male, mounted, 

 in bad condition, much faded, skull in situ ; labelled Egypt (lieg. 

 no. A. 69). The species was figured eight years later in 'Descrip- 

 tion de I'Egypte ' {I. s. c).
