The above description gives the present appearance of the type of 

 this species. While it has undoubtedly faded somewhat in the more 

 brilliant and delicate colors, its general aspect cannot have changed 

 much, and what is now dark brown was never black as given by most 

 authors as the color of the body ; for the head, hands, feet and tail are 

 as black as they probably ever were ; the tail alone showing a purplish 

 tint which no doubt always existed. The brilliant orange red of the 

 under parts still remains where the hairs have not disappeared. 



Measurements. Total length, 520; tail, 390, (skin). Skull : occip- 

 ito-nasal length, 46; Hensel, 31; palatal length, 15; intertemporal 

 width, 23 ; median length of nasals, 8 ; length of upper molar series, 9 ; 

 length of mandible, 28; length of lower molar series. 11. 



The type of Midas ruRventer Gray, is like L. l.abiatus but has a 

 small gray spot on the crown between the ears and the nape. This is 

 probably an individual peculiarity, and is the only difference in color
