NOISy DOUROUCOULI. 



Type locality. Tabatinga on the Upper Maranon, eastern border 

 of Peru. Type in Munich Museum. 



Geogr. Distr. Upper Amazon ; on banks of the Ucayali and Hual- 

 laga rivers, and on the Upper Maranon on eastern border of Peru ; 

 the mountains of Tolima, Colombia. 



Genl. Char. Hair, long, loose, fluffy, thick ; color uniform. 



Color. Spot over and beneath each eye white ; a fan-shaped black 

 spot on center of head, and a lateral black line extending back on each 

 side of the head towards occiput ; entire upper parts and limbs cinna- 

 mon rufous, darkest on head and dorsal lines which are more reddish ; 

 under parts ochraceous buff ; inner side of limbs grayish buff ; hands 

 and feet blackish brown, reddish in type ; tail at base like dorsal line, a 

 reddish cinnamon rufous, remainder black. The type of A'^. lemurinus 

 I. Geoffroy, in the Paris Museum, has been examined, but it is so faded 

 from exposure to light that it is impossible to recognize its original 

 coloring, and one could only guess at it. 



Measurements. Skull : occipito-nasal length, 58 ; zygomatic width, 

 40 ; intertemporal width, 30 ; median length of nasals, 12 ; breadth of 

 braincase, 32; palatal length, 19; length of upper molar series, 14.5; 

 length of mandible, 36; length of lower molar series, 15. 



The type of this species is in the Munich Museum, but is now in 

 a very poor condition. The hair has gone from the face and from a 

 portion of the head over the right eye. There is no trace remaining 

 of the black line on the side of the head, and the triangular black spot 

 on top of the head has disappeared, while only a few hairs above and 

 below the eyes indicate the white spots formerly existing. The fur is 

 much faded, and discolored by time and exposure There was no skull 

 preserved. 



In the Proceedings of the London Zoological Society, 1872, p. 3, 

 Mr. Sclater identified a specimen stated by Dr. von Patten to have 

 been collected in the forest of Quindin, Costa Rica, as the same as 

 this species under the name of N. lemurinus. The locality given is 

 probably an error, as no species of Actus is known to inhabit any part 

 of Central America, and Alston (1. c.) says that Mr. Salvin thought a
