nigro, fascia humerali alba" ( = Sus patira Sonnini, 1803 = 

 Sus tajacu Linn., 1758). Tayassu pecari G. Fischer, 1814, 

 antedates Sus albirostris Illiger, 1815, by one year, and 

 Dicotyles labiatus Cuvier, 1817, by three years, for the same 

 animal, namely, the Tagnicati of Azara (Quad. Parag., I, 

 1 80 1, p. 25), of which the type locality is Paraguay. 



The Peccaries, as now recognized (excluding extinct forms), 

 with their principal synonymy, stand as follows: 



GENUS Tayassu FISCHER. 



Tayassu G. FISCHER, Zoognosia, III, 1814, 284. 

 Dicotyles CUVIER, Regne An. I, 1817, 237 = Tayassu Fischer. 

 Notophorus G. FISCHER, Mem. Soc. Imp. des Nat. de Moscou, V, 

 1817, 418. Given to replace his previous barbarous name Tayassu. 



SUBGENUS Tayassu (EX FISCHER). 



Tayassu MERRIAM, Proc. Biol. Soc. Wash. XIV, 122, July 19, 1901. 

 "Restricted to the tajacu-angularis group." 



Notophorus GRAY, P. Z. S. 1868, 43. Type and only species, Sus 

 tajacu Linn. Preoccupied by Notophorus Fischer, 1817 = Tayassu 

 Fischer, 1814. 



i. Tayassu tajacu (Linn.). 



Sus tajacu LINN. Syst. Nat. 1758, 50. Based on Piso, Marcgrave 

 Hernandez, etc. ; diagnosis distinctive for the Collared Peccary 

 group, but references composite. First properly described and dis- 

 tinguished from the White-lipped Peccaries by Azara, as below; hence 

 it would be well to recognize Paraguay as the type locality, on the 

 basis of Azara's 'restriction.' 



Le Taytetou, Sus tajassu Linn. AZARA, Quad. Paraguay, I, 1801, 

 31. Sus tajacu Linn, restricted. Not Sus tajassu Erxleben, Gmelin, 

 and other early compilers, which comprised all then known Peccaries. 



Sus patira SONNINI, Nouv. Diet. d'Hist. Nat. XVII, 1803, 180 = 

 Taytetou, Azara, /. c. p. 31. 



Tayassu patira G. FISCHER, Zoognosia, III, 1814, 287 = Sus patira 

 Sonnini, 1803. 



Dicotyles torquatus CUVIER, Regne An. I, 1817, 237. Based on 

 Azara as above cited, and hence also relates primarily to the Para- 

 guayan animal. 



2. Tayassu angulatus (Cope). 



Dicotyles angulatus COPE, Am. Nat. Feb. 1889, 147, May 25, 1899. 

 Texas.
