278 LASIOPYGA 



LITERATURE OF THE SPECIES AND SUBSPECIES. " 



1758. LintKBus, Systema Natures. 



Two species are here recorded which have been referred to the 

 genus Lasiopyga: Simia diana and >$". athiops. The first is 

 the well known Moni<ey, Lasiopyga diana from Liberia, the 

 other, however, is not so easily determined. De Winton (1. c.) 

 considers it to be the species afterwards called by Desmarest 

 (1. c.) C. GRiSEOViRiDis from the region of the Upper Nile, 

 Abyssinia, Sennaar and Kordofan, but Linnaeus' description, 

 which was evidently taken irom Hasselquist's, for it is doubt- 

 ful if he ever saw a specimen, presents certain difficulties that 

 make it more than probable some other animal than the one 

 from the White Nile was intended. The difficulty is met with 

 in the sentence "Cauda tecta, subtus ferruginea." Now the 

 tail of the White Nile species is speckled grayish above, and 

 white beneath, and this fact would seem at once to compel us 

 to believe that athiops Linn., is not the same. The Linnsean 

 species may possibly be L. ascanius which has a red tail above 

 and below except at the base, or L. cephus of which in the 12th 

 edition he makes a variety. That it belongs to one of the 

 Petaurista, or so-called Athiops groups is most likely, but its 

 determination is not easy of accomplishment, and all that can 

 be said with any degree of certainty is, that, while in some 

 degree it resembles C. griseoviridis Desm., it is not that 

 species, nor can it be referred to any known species, and must 

 therefore take a place among the undeterminable forms. 



1766. Linnaus, Systema Natures. 



In this the 12th edition of Linnaeus' work under Simia, four 

 species, now placed in Lasiopyga, are given, but among them, 

 (Ethiops, of the 1758 edition, as a species is not found. They are 

 S. diana; (S.) sabcea undeterminable; {S.) cephus; and (5".) 

 NicTiTANS first described. Under {S.) cephus var. B, is (5".) 

 (Bthiops, but in the diagnosis no mention is made of the color of 

 the tail, simply caudata imberbis, showing it was a long tailed 

 monkey. Evidently Linnaeus was not certain of the distinctness 

 of his S. wthiops, and so in his edition reduced it to a variety of 

 a reddish tailed species.
