Lastly, the mountainous Crimea, its wooded parts as well as the. region along the mountain ranges of the Jaila is inhabited by the small V. v. krymea-montana BRAUNER. Vulpes vulpes diluta OGNEV (1924). The pale fox. 1914. Vulpes vulpes crucigera (partim !) SATUNIN, Conspectus Mammalium Imperii Rossici, p. 138. 1924. Vulpes vulpes crucigera diluta OGNEV, The fauna of the Terrestrial Ver tebrates of the gvt. of Voronesh, p. 102—110. Type locality. — Kamennaya steppe, Bobrovsky district, gvt. of Voronesh. Diagnosis. — General tint of colouring visibly paler, duskier and yellower. Fur not so downy and thick, as that of the preceding subspecies, but coarser and scarcer. White-bellied foxes predominate. Skull somewhat larger, than that of the central Russian fox. General length of skull of cfcf 150-7—161 (M. 155-7). of 99 141-7—144-6 ; condylo-basal length of cfcf 147-2-1566 (M. 150-6), of 99 136-1—140 1; zygomatic breadth of cfcf 79—84'5 (M. 82*3), of 99 74'8—

79*1 ; utmost breadth of skull of cfcf 48—53-4 (M. 50"5), of 9$ 46-7—50-2; length of brain-case of cfcf 62-6—65-3 (M. 64-2), of 99 60'3—

62*1; length of facial part of cfcf 63-9—70-3 (M. 67'1), of 99 611—66-9; height of skull of cfcf 50'2—

54 (M. 52-7), of 99 49-2—51-9; length of upper tooth-row of cfcf '66-1—721 (M. 68"8), of 99 61-1—68-5. Systematic remarks. — As has been mentioned above, V. v. diluta OGN. represents a doubtless transitive stage to V. v. karagan ERXL. ; on the points of contact of these forms, one undoubtedly meets with specimens, the exact taxonomical position of which it is difficult to establish. Only the typical individuals of the sub-species in question — the pale fox and the typical Karagan — are comparatively easy to define. The geographical distribution has been mentioned above.
