the species commonly known as Lophoceros kartlaubi. In fact, it bears 

 less apparent relationship to the species with which it has usually been 

 associated than it does to Ortlwloplius leucolophus. From OrtholopJms 

 the present genus may be satisfactorily distinguished by the absence 

 of a conspicuous crest, and particularly by the comparative length of 

 the tail, which is barely longer than the wing, instead of about twice 

 as long.
