498 Mr. C. T. Regan on the Cichlid Fishes 



in A. k. adolfi-friderici, except that the white of the chin 

 and throat is more conspicuous. 



Skull. Much as in A. k. adolfi-friderici, but smaller. 

 Horns thinner at base and distinctly more curved in their 

 basal portion. 



Dimensions of fi/pe skull. Basal length 255; upper length 

 287; palatal length 149; palatal widtli inside wig 39*5; 

 postorbital width 114; zygomatic width 1025; mastoid 

 width 93; nasals, length 109, greatest brendth 23*9 ; breadth 

 of rostrum across premaxilla^ 39'5 ; length of upper tooth-row 

 (alv.) 72'4; horns, length along curve 510, greatest diameter 

 at base 54"8. 



Adenota koh uhangiensis, sub?p. nov. 



Type locality^ Duma, near Libenge, Ubangi River. 



Type. J. Senckenberg Museum, Frankfurt-a.'M. Jour- 

 nal no. 215. Original number 18. Collected {September 25th, 

 1910, by Dr. H. 8chubotz (no skull). 



Nearly allied to Adenota k. hahr-keeicC) but still darker, 

 and with a distinct suffusion of black. 



Colour of ''mantle" much like the " ru ochre ^^ of the 

 * Eep. de Couleurs,' but somewhat more brownish, and 

 distinctly but finely speckled with black, especially poste- 

 riorly. No speckling on legs, neck, shoulders, and face. 

 *' Intermediate ■'\«one near " cinnamon" no. 1, thighs only 

 slightly darker. Black maikings and distribution of white 

 as in A. k. bahr-keetce. 



Only the skull of a young specimen has been examined. 



A specimen from Crampel, Gribiugi (Upper Shari) River, 

 combines the slightly larger size of A. k. hahr-heetce with the 

 dark fulvous colour of A. k. uhangiensis. As a matter of 

 fact, the three forms of Adenota just described are very closely 

 allied ; more material from intermediate localities will most 

 certainly show them to intergrade, but the extremes at hand 

 are different enough from each other to deserve subspecific 

 rank.

In 1905 (Proc. Zool. Soc. pp. 152-168) I published a revision
