Remarks. With a small series of each of the forms of the anomalus 

 series before me, it is obvious that the one here described is sufficiently 

 characterized for recognition, although it may be found to have a limit- 

 ed range. Specimens from San Julian, Venezuela, in the collection of 

 the U. S. National Museum, supposed to represent " melanoleucus ," 

 seem to be tending slightly toward brachialis but are much nearer typical 

 anomalus. Since the original description of melanoleucus states "legs 

 and feet black" there can be little doubt that the type is of the dark 

 form of eastern Venezuela and Trinidad. The majority of the speci- 

 mens of H. a. jesupi seem to be almost or quite as dark as anomalus, 

 differing mainly in the white inner sides of the arms. 



Our specimens, six in number, were obtained under may as and thorny 

 shrubs which form hedgelike borders to the trails leading in various 

 directions from El Panorama. 



Dasyprocta rubrata f lavescens Thomas. Yellow-rumped Agouti. 



One specimen, El Panorama, Rio Aurare, Jan. 23. 



This example, an adult male, was shot as it crossed a trail one even- 

 ing just before dark. A few tracks of others were seen in various places, 

 but with the one exception, the animals themselves succeeded in evading 

 observation. 



No material is available for comparison, but judging from descriptions 

 our specimen differs but little from typical flavescens, possibly being 

 slightly larger and darker. 



Local name Picure. 



Dasyprocta variegata colombiana Bangs. Colombian Agouti. 



A skull of a young Dasyprocta, apparently of this .species, was ob- 

 tained in Maracaibo from a market hunter who said it came from the 

 Limon River some 20 miles west of Maracaibo. 



Agouti sierrae Thomas. Mountain Paca. 



Said to be fairly common in certain heavily wooded parts of the 

 mountains. We did not find it on Paramo de Tama although it is 

 well known to the natives there. 



Local names Lapa and Tinaja.
