Resumen
Se presentan nuevos antecedentes acerca de Felis geoffroyi leucobapta, Arctocephalus gazella y Galictis cuja cuja en la región de Magallanes.
La presencia de Felis geofroyi leucobapta no ha sido reportada hasta ahora en Magallanes. Se entregan informaciones sobre la talla y sexo no publicadas con anterioridad. El ejemplar capturado más recientemente (1974) amplía el rango distribucional Sur de esta
especie en 135 km. (52° 45'5).
Los anillos de marcaje de un ejemplar de Arctocephalus gazella fueron recuperados en Bahía Orange, Isla Hoste (55° 30'S; 68° 07'W.). Este ejemplar había sido marcado en las islas Georgia del Sur (54° OO'S; 38° 02'W). Este hallazgo es al parecer la primera
demostración reportada del notable desplazamiento occidental de esta especie. Pese a que más individuos de A. gazella han sido encontrados en la región, su ocurrencia es considerada accidental.
Se reporta por primera vez para Magallanes Galictis cuja cuja sobre la base de dos especímenes. Considerando el límite septentrional conocido para esta especie, este hallazgo representa una extensión del rango distribucional sur de más de 1.000 Km. Se in
cluyen fotografías de la maxila y mandíbula de uno de estos ejemplares, junto a medidas corporales y craneales de ambos ejemplares.
New information about Felis geoffroyi leucobapta, Arctocephalus gazella, and Galictis cuja cuja in Magallanes (Región XII). Chile is presented. It is considered that the ocurrence of Felis geoffroyi leucobapta in the Province of Magallanes, Chile, has never been presented formally in the literature previously. Additional information on size and sex, previously unpublished, is given also. The most recent (1974) specimen obtained, extends the southern range of this species in the province by 135 kilometers to 52° 45'S. Metal tags were recorvered in Bahia Orange, Isla Hoste (55° 30'S; 68 07'W) from an individual of Arctocephalus gazella that had been tagged on the South Georgia Islands(54° OO'S; 38° 02'W). This find is apparently the first demostrating such a notable westward extensión of this species. Until more individuals of A. gazella are found from the province its ocurrence is considered accidental. The presence of Galictis cuja cuja (Quique), is reported for the first time in the province of Magallanes, Chile, on the basis of two specimens. Based upon the previously known limits of this species this represents an extensión of more than 1.000 Km. south. Photograhs of the uppers and lower jaws of one of the specimen, plus measurements of bodies and craniums are given for both specimens.
