snbsprcios. The latter will therefore both need new names, 

 as will also the small race from the Island of Trinidad. 



The three chief subspecies, passing from north to south, 

 n ay be briefly recognized as follows : — 



]. Galictis Barbara senex, subsp. n. 



Head and neck white orgreyish white, conspicuously different 

 in colour to the rest of the animal, and rather sharply separated 

 from the black of the shoulders. As in the South-xA.merican 

 form, the face is darkerthan the crown and neck, and the latter 

 is more or less suffused with yellow. Size rather greater than 

 in the next subspecies. Skull of male 109 millira. in basal 

 length by 76 in greatest breadth. 



Hah. Hacienda Tortugas, Jalapa, Vera Cruz. Alt. 

 190 metres. 



Ti/pe (male) B.M. no. 89. 12. 7. 4. Collected in No- 

 vember 1888, and received from the Mexican Museum. 

 (Specimen a of P. Z. S. 1890, p. 72.) 



Native name " Cabeza de Viejo," which has suggested the 

 technical name now given. 



2. Galictis harhara hiohgia?.^ subsp, n. 



Head and neck brown, scarcely lighter than the back, 

 dfcidedl}' darker than in typica^ and far darker than in senex, 

 the darkest-headed form therefore occurring between the two 

 lightest-headed subspecies. Unlike either of the other two 

 forms, the neck is even darker than the head, its colour 

 passing quite gradually into that of the back. 



Skull of female 98 millim. by 63. 



Hah. of t3'pe : Calovevora, Veragua, Panama. Another 

 specimen from Costa Rica. 



Type B.M. no. 69. 7. 19. 1. Received from Mr. O. 

 Salvin ; collected by E. Arce. 



The name now given both commemorates the magnificent 

 work published by j\lessrs. Salvin and Godraan, and also 

 exactly applies to the animal, as it is the Galictis harhara of 

 the ' Biologia,' though the white-headed Mexican form is also 

 referred to in that work. 



While considering for the present both these new forms of 

 the Tayra merely as subspecies, as they are certainly the 

 local representatives of the typical G. harhara, I think it 

 probable that at least the northern white-headed senex will 

 prove to be so sharply separated from hiologice as to need 

 specific rank. The latter, on the other hand, will more 

 probably be found to grade into the South-American race as 

 further material becomes available.
