Collared peccaries are still hunted with dogs ; they are smaller, more 

 easily overtaken, and are not regarded as so dangerous either to the 

 dogs or hunters as the white-lipped peccary. 



Alston (1879, p. 107) recorded the species from Panama as living 

 in the gardens of the Zoological Society of London. 



Specimens now recognized as P. a. bangsi from Gatun and Real de 

 Santa Maria were assigned by Anthony (1916, p. 364) to Pecari 

 crusnigrum. 



Specimens examined: Boca de Cupe, 1 ; Escobal (Gatun Lake), 

 1 * ; Gatun, 5 2 ; Real de Santa Maria, 2. 1 



Genus TAYASSU Fischer. White-lipped Peccaries 

 The white-lipped peccaries are larger and blacker than the collared 

 peccaries of the genus Pecari, and are further distinguished ex- 

 ternally by conspicuous white areas extending from the mouth along 

 the sides of the face. The skull of Tayassu, contrasted with that of 

 Pecari, differs notably as follows : The rostrum is broadly flattened 

 above (not narrow and highly arched along the median line) ; the 

 maxillae are greatly expanded laterally over the first premolars ; the 

 palate lacks the distinct marginal ridge extending in Pecari from the 

 canine to the anterior premolar; the molar cusps are more closely 

 connected by intermediate cusplets. 



TAYASSU PECARI SPIRADENS Goldman 



Costa Rican White-lipped Peccary; Puerco de Monte 



Tayassu albirostris spiradens Goldman, Proc. Biol. Soc. Washington, Vol. 25, 

 p. 189, December 24, 1912. Type from Talamanca, Costa Rica. (Prob- 

 ably near Sipurio, in the valley of the Rio Sicsola.) 



The Costa Rican white-lipped peccary inhabits Co'sta Rica and ad- 

 joining territory ; and is doubtless generally distributed in the forests 

 of the greater part of Panama. It is one of the few mammals known 

 to occur in the region but of which no specimens are as yet 

 available for examination. Eight skulls in the Museum of Compara- 

 tive Zo'ology collected by G. A. Maack on the Isthmus of Panama 

 are referable to this form, but the indefinite locality may apply to 

 what is now Colombian territory. In the vicinity of the Canal Zone, 

 where it is known to the natives as " puerco de monte," the white- 

 lipped peccary occurs in much smaller numbers than the collared 

 species. Unlike the latter animal it gathers in herds which may 

 number 100 or more individuals. These herds move steadily about,
