LETTER FROM PROF. SPENCER F. BAIRD. 



183 



March 12, 1868. 



George Busk, Esq., F.R.S., V.P., in the Chair. 



Mr. P. L. Sclater exhibited a stuffed specimen of a Monkey (Cer- 

 cocebus albiffena*) from Mr. J. J. Monteiro's collection, which had 

 been procured by that gentleman from Cabinda, north of the river 

 Congo. The only exact locality previously recorded for this species 

 was stated to be Gaboon (Dm Ckaillu), whence it would appear to 

 extend down the northern Ijank of the Congo. 



An extract was read from a letter addressed to Mr. Sclater by Dr. 

 W. Peters, For. Memb., stating that a skull of the singular Rodent 

 lately described by M. Alphonse Milne-Edwards under the name 

 Lophiomys imhausii, in the zootomical collection at Berlin, had been 

 obtained by Dr. Schweinfurth from the tombs of Maman, northwards 

 of Kassala in Upper Nubia. 



Mr. Sclater remarked that this fact was of great importance as 

 giving an indication of the true patria of this Mammal, which was 

 unknown to M. Milne-Edwards, and stated that he had particularly 

 called the attention of Mr. Jesse, who was accompanying the Abys- 

 sinian Expedition, to the desirability of obtaining specimens of it. 



A letter was read from Prof. Spencer F. Baird, For. Memb., dated 



Catkartes californiaHUs, jr.
