AND THE ,,ROLOWAY." 235 



audi mit seinen Haaren so gleich , als ware es gekammt. 

 Aber darinnen bat der Bart etwas besonders, dass er an 

 der Vorderseite scbwarz , wie das Gesicbt ist, aber an der 

 untern Seite ist er langer und ganz weiss wie das Kinn" '). 

 This description of the color of the thighs , of the white 

 crescent on the forehead and of the beard and of the 

 animal furtheron indeed , is so exactly a description of 

 our Liberia-monkeys, that one could hardly produce a 

 better one. In the 10th edition of his Systema naturae 

 Linnaeus described the animal under the title Simia diana, 

 so that we have to name it Cercopithecus diana (Linné). It 

 appears therefore that the animals which have been called 

 by Dr. Gray var. ignitus or ignitus-^^ecie^ by Sclater were 

 true Cercopithecus cZz'awa-speciraens, having bright red-bay 

 inner side of thighs , a short white beard and a white 

 crescent on the forehead , contrary to what always has 

 been accepted , so that what has been called in all books 

 C. diana ^), viz. the Monkey with white inner side of thighs, 

 a long white beard and a white band or diadem on the 

 forehead , requires an other specific title. And there has been 

 described and figured a species presenting all the named 

 characteristics: this is the »Roloioay" of Allamand.

1) The text in the Handlingar, p. 212, runs as follows: -/Haren pa inra sidorna 

 ./af laren alt infvan svansen bart til knavecken aro af en rod rost-farg, som 



./set ut liksona han hiir vore blodig Fronten eller ögenbrynerna ga til- 



//sammans med langre, hvita, upratta och tilbaka bögda har, aldeles som de 

 «nymodige Tupeer, hvarigenom en hvit mane förestalles i pannan, emedan 

 //desse haren aro hvita pa spitsen; men om hon har efter nya modet Toupée 

 //i pannan, sa liar hon ook pa hakan skagg efser gamla modet. Detta skagget, 

 //sitter pa en mera fet haktipp , ar smalt, kart och studsat eller liksom tvart 

 //afklipt, pa andan , samt ligger jamnt med sina har, som vore det kammat. 

 //Men skagget ar synnerligt deruti , at det pa framre sidan ar svart , sasom 

 //ansigtet , men pa undra sidan langre och helt hvitt, sasom hakan" 



2) The -/Diane, femelle" figured and described in 1824 by GeofFroy St. 

 Hilaire and Cuvier was a Monkey quite different from ./Diana" and ./Roloway." 

 La Diane of Audebert (Histoire naturelle des Singes et des Makis) was a 

 true C. rolowaij.
