LaSIOPYGA NICTITANS LAGLAIZI (PoCOck). 



Cercopithecus nietitans laglaizi Pocock, Proc. Zool. Soc. Lond., 

 1907, p. 698. 



Type locality. Gaboon. 



Genl. Char. Similar to L. nictitans, but hair longer and grayer. 



Color. General hue slightly grayer than L. nictitans, otherwise 

 no difference is perceptible. Ex type British Museum. 



Measurements. Size about same as L. nictitans. The skull 

 attributed to this type specimen is that of a very young female, and 

 evidently never belonged to it. 



The type has been in the British Museum Collection since 1880, 

 was mounted and has been made into a skin. It formerly belonged 

 to the La Glaize Collection and bears on the ticket the locality 

 "Gaboon." This is so close to the Benito River, for I suppose 

 'Gaboon' River is intended, that it is not to be expected there could be 

 in the territory two distinct forms. The L. n. laglaizi is most doubt- 

 fully separable from L. nictitans.

 Central Africa.
