CEPIIALOPHUS SILVICULTOH. 183 



The direction of the loug uaked line formed by the 

 row of pores in which the aute-orbital glands open has 

 been much better and much more exactly reproduced on 

 plate XIV of the Book of Antelopes than on plate XIII, 

 which represents our Rotterdam-specimen, as it does not 

 originate from the anterior corner of the eye, but much 

 lower, slantly between eye and muzzle. 



The skull of silvicultrix has been thrice figured, once by 

 Gray in 1865 under the title of Cephalophus longiceps 

 (skull sent from the Gaboon by Du Chaillu), again in 

 1871 by the same author under the name of Cephalophus 

 sylvicultrix (a skull from Sierra Leone) and finally in the 

 very paper and by the same author again under the spe- 

 cific title of Cephalophus melanoprymnus (skull from the 

 Gaboon). The worst of all these reproductions is the first 

 one (P. Z. S. L. 1865, p. 205), it has been so wrongly ') 

 drawn that it must induce anyone in error if compared 

 with a skull; the second figure (P. Z. S. L. 1871, p. 596) 

 is a very good one, as will be evident if compared with 

 the figures (photo's) of the specimens in the Leyden Mu- 

 seum ; the artist however has overlooked and therefore not 

 reproduced the processus corouoideus. The third figure (P. 

 Z. S. L. 1871, p. 594) is that of a young female, belong- 

 ing to a skin (the other two without skins) : this drawing 

 agrees quite exactly with the skull of the young specimen 

 in our collection, it is of the same size apparently, although 

 Gray did not mention its measurements nor the size of the 

 stuffed specimen out of which it had been taken : this 

 conformity of the skull as well as that of the specimen 

 itself as figured (P. Z. Ö. L. 1871, plate XLIV) by Gray 

 with both our young specimen and its skull abolishes all 

 doubt whether our specimen truly is a young silvicultor. 



Again and again I compared the skulls of silvicultor 

 with those of Jenti?iki, but the differences I could hunt 



1) If it however has been correctly drawn, then it has nothing at all to 

 do with silvicultor.
