Seasonal morphological variations: Different morphological parameters like head to body length, ear length, tail length, hind foot length, basal length, condylobasal length, greatest skull length, nasal length, zygomatic breadth, palatal length, mandible length, interorbital breadth, postorbital constriction, mandible toothrow, maxillary toothrow, nasal breadth, biorbital
breadth and palatal breadth were measured as indicated in Table I.
The skull of this specimen, identified based on teeth as an adult margay (deposited in the collection of mammals at Centro de Investigacion en Biodiversidad y Conservacion) does not have a sagittal crest and its measurements (mm) are: greatest length of skull, 93.4; height of skull, 48.0; zygomatic breadth, 66.3; length of maxillary toothrow, 28.0; length of mandibular toothrow, 31.0; length of mandible, 62.2; interorbital width, 18.0; biorbital
breadth (distance between outer borders of boney orbits), 58.0; height of braincase, 35.0; and width of braincase, 45.0.
