which appears on the occipital surface narrow and high, not 

 broadly rounded. Lower jaw with its angular region far 

 broader than in G. Mechoioi. 



Teeth large and heavy, the incisors very broad. 



Dimensions of the type (measured in the flesh) : — 



Head and body 2G0 mm. ; tail 24 ; hind foot, s. u. 40, 

 c, u. 44. 



Skull : greatest length in middle line 58 ; basilar 

 length 49 ; zygomatic breadth 43*5 ; nasals 23*3 X 7*4 ; 

 interorbital breadth 19 ; breadth across postorbital processes 

 20"6 ; intertemporal constriction 11'3; least breadth above 

 meatus 19; palate length 37; diastema 22; combined 

 breadth of two upper incisors 8 ; height of angular region 

 of lower jaw, from top of condyle, 27. 



Hah. and Type as above. 



This fine species may be readily distinguished from 

 G. Mechowi^ Peters, its only near ally, by its larger size, 

 more inflated interorbital region, and the other details above 

 recorded. The type of G. Mechowi came from Malanje in 

 Northern Angola, quite near to Duque de Braganza, whence 

 Dr. Ansorge obtained in his previous collection the examples 

 we have used in making the above comparisons.

 These specimens are smaller than the type of G. Bocogei^
