1902.] THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 237 



Total length 220 inillim. 



A single specimen from the Lukula River, preserved in the 

 Royal Natural History Museum, Brussels. 



I avail myself of this opportunity to propose the name of 

 Pelmatochromis jiolyodon for the fish from Monsembe which I 

 have recently described (Ann. Mus. Congo, Zool. ii. p. 53) as 

 P. tceniahts, having ovei-looked the fact that the same name had 

 been previously bestowed on a species from Nigeria.

The Seci'etaiy read the following report on the additions made 

 to the Society's Menagerie in March 1902 : — 



The registered additions to the Society's Menagerie during the 

 month of March were 146 in number. Of these 38 were acquired 

 by presentation, 18 by purchase, 3 were born in the Gardens, and 

 87 were received on deposit. The total number of departures 

 during the same period, by death and i-emovals, was 143. 



Amongst the additions attention may be specially directed 

 to:— 



1. A Monkey of the genus Ge^'copithecus, procured by Major 

 Delme-RadclifFe in the Latuka. Mountains, about a hundred miles 

 east of the Upper Nile in Northern Uganda, and pi'esented to the 

 Society on March 1st. This Monkey appears to belong to a new 

 species allied to Cerco]nthecus leucampyx, but easily distinguish- 

 able by the white eai'-tufts and grey back. I propose to name 

 it Delme-Radcliffe's Monkey {Cercopithecus otoleucus). It may 

 shortly be described as follows : — 



Cercopithecus OTOLEUCUS. (Plate XXY.) 



Above fuliginous, back more or less grizzled with pale fulvous, 

 head above black ; frontal line white, with hairs rather elongated ;
