[s-ic] Traill (1821) was based on a specimen "brought to Eng- 

 land from Demerara," and is therefore also a synonym of M. 

 barbara Linn.; the -V//.s~/<;/a barbara var. laira F. Cuvier 

 was also from Guiana. Eira ilya H. Smith (Nat. Libr., XV, 

 1842, 203) was based on a crude drawing, by Prince John of 

 Nassau, in the Berlin Library, of an animal from Guiana, 

 and hence requires no further consideration. 



The forms of the group heretofore recognized are : 



Tayra barbara barbara (Linn.). Guiana, Venezuela, and Brazil. 



Tayra barbara peruana (Tschudi). 1 Peru, east of the Andes. 



Tayra barbara senex (Thomas). Mexico. 



Tayra barbara biologies (Thomas). Central America. 



Tayra barbara trinitatis (Thomas). Trinidad. 



Tayra barbara brunnea (Thomas). Western Bolivia. 



Tayra barbara irara Allen (as above). Northeastern Colombia. 



17. Nasua narica (Linn.). Seven specimens, March 11-16 

 and April 16. They are mostly only about two thirds grown, 

 but two are young adults. These, male and female, measure, 

 respectively: Total length, $ 1143, ? 980; tail vertebrae, 

 6 550, ? 475; hind foot, $ 105, ? 100. Skulls: Total 

 length, $ 128, $ 122; zygomatic breadth, $ 60, ? 58. 

 Old specimens would be much larger, especially in the cranial 

 measurements, and particularly in zygomatic breadth. 



1 Galictis barbara TSCHUDI, Fauna Peruana, 1844-46, 107. Description based on a 

 Peruvian specimen in captivity. 



Galictis barbara var. peruana TSCHUDI, Wiegm. Arch., 1844, i, 248. Based on the 

 description in 'Fauna Peruana.' 



In this description Tschudi states that, like many other mammals and birds common 

 to Peru and Brazil, the Peruvian representatives are not quite the same as the Brazilian; 

 although the color pattern is the same, the Peruvian animals are much more intensely 

 colored; but he considers such differences local and climatic, and not really of specific 

 value. He notes further that his description of what he here designates Galictis bar- 

 bara does not agree altogether with Brazilian examples. In his ' Mammalium con- 

 spectus quae in Republica Peruana reperiuntur et pleraque observata vel collecta sunt 

 in itinere a Dr. J. J. de Tschudi' (Wiegm. Arch., 1844, i, pp. 244-255, dated Dec., 1843), 

 he appears to have decided to recognize the Peruvian form of this animal as a variety, 

 referring to the ' Fauna Peruana ' as the basis for the name. As no page or plate refer- 

 ence is given, in this as in other cases in the ' Conspectus ' where new names appear, it 

 is probable that the ' Fauna,' although in press, had not at that time appeared, and 

 that the new names (17 in number) employed in the 'Conspectus' were nomina nuda 

 until Volume I of the Fauna was published. This ('Therologie,' half-title, following 

 p. xxx) is dated 1844; but there is internal evidence^that it could not have appeared 

 prior to July, 1845 (see p. 262, footnote). As in the interval between the publication 

 of the ' Conspectus ' and the mammal part of the ' Fauna ' no other name was proposed 

 for the Peruvian Tayra, it seems admissible to adopt peruana from Tschudi, as was 

 done by Dr. Nehring in 1866 (Zool. Jahrb., 1886, i, p. 206). 



All of the other new names in the 'Conspectus' appear also in the 'Fauna,' and 

 their status is thus without question. This includes Tschudi's Cervus nemorivagus var. 

 peruana (Conspectus, /. c,, p. 255), which, while not adopted in the text (Fauna, p. 

 240), appears in the ' Systematische Zusammenstellung' on p. 20. This antedates by 

 about ten years Wagner's Cervus tschudii (Schreber's Saugth., Suppl., V, 1855, pp. 386, 

 387), based wholly on Tschudi's description. The Peruvian Brocket will thus stand as 

 Mazama peruana (TSCHUDI).
