An. Z. S. 1896, p. 155, ex. _f._ (_err._). _Gazella marica_, =Thos.= Ann. Mag. N. H. (6) xix. p. 162 (1897). VERNACULAR NAME:--_Reem_ of Arabs of Nejd (_Jayakar_). Closely allied to _G. subgutturosa_, with which it shares the substitution of white for the dark colour of the central facial band, the general plan of coloration, and the curvature of the horns. Size, however, very markedly smaller. General colour pale fawn. Facial markings almost obsolete; when distinguishable they are only of the general body-colour and very slightly defined from the paler bands between them. Ears long, their backs whitish fawn. Pale lateral band scarcely visible; dark lateral band and pygal band pale brown, little marked, scarcely darker than the dorsal colour. Limbs whitish throughout; distinct knee-tufts present. Skull and horns, so far as the male is concerned, very much as in _G. subgutturosa_, although much smaller. Basal length of skull (in an old male) 6·1 inches, greatest breadth 3·15, muzzle to orbit 3·45. _Female._ Similar, but horns only from 3 to 5 inches in length, slender, straight or slightly curved. _Hab._ Arabian Desert, from Nejd in Central Arabia to Western Oman.
