Subfamily. Alouattinae 

 GENUS ALOUATTA. 



Alouatta palliata inconsonans Goldman 



Alouatta palliata inconsonans Gold., Smith. Misc. Coll., 60, 1913, 

 p. 17. 



Type locality. Cerro Azul, near the headwaters of the Charges 

 River, Panama, Elevation 2,500 feet. Type in United States National 

 Museum. 



Genl. Char. Like A. palliata but black color less suffused with 

 brownish or rufous. 



Color. Upper parts varying from pure black to black finely and 

 usually rather inconspicuously mixed with buff over most of dorsum 

 leaving head and rump pure black, under parts in general thinly haired, 

 black or dark brownish, becoming lighter through varying shades from 

 burnt umber of Ridgway to brownish ochraceous on the long hairs 

 overhanging lower part of sides ; chin, arms, legs and tail pure black. 

 Skull with braincase broader posteriorly ; zygomata usually more 

 squarely spreading posteriorly ; supra-occipital protuberance shorter 

 and more projecting; interpterygoid fossa broader, bullae flatter; pre- 

 molars narrower. 



Measurements. "Total length, 1,272; tail vertebras, 71.5 ; foot, 143. 

 Skull (Type) : Greatest length, 123.5; zygomatic breadth, 87.2; length 

 of nasal, 21.8; anterior width of nasals at median constriction, 8; inter- 

 orbital breadth, 12.2; palatal length, 46.8; maxillary tooth row, 29.4; 

 width of crown of third upper premolar, 7.7 ; antero-posterior extent 

 of supra-occipital protuberance (from lamboid suture), 14.1." 



I have not seen this example, but it seems to possess only slight 

 differences from A. palliata.
