APPENDIX II November 1930. Jurbaib, 30 feet, i8th November 1930. Khor Salala, sea-level, 24th November 1930. These specimens all appear to be rather blacker on the ventral surface than the typical Fulpes vulpes arabica. The type of this race comes from Muscat, and the Museum collection possesses a series of specimens from various localities in Arabia, as well as specimens from Persia and Egypt which probably belong to the Arabian race. Fennecus sp. Arabian Fennec Fox. One specimen. This Fennec would appear to represent an Arabian race of the Egyptian Fennec which is found in North and North-east Africa, The Museum possesses one specimen from the desert of Al Kuwait in Arabia, which may be useful to compare with the present specimen when the time comes for working out these interesting foxes. Mellivora ratel (Sparrm.). Ratel, Sha'ab Fuzul, 250 feet, i8th November 1930. The Ratel is found over a very great part of Africa south of the Sahara and extends eastward into India. Very little variation in colour or size can be found between the African and Indian forms, and at the most they would appear to be merely geographical races. Gerbillus arduus (Chees, and Hint.). Arabian Gerbil. Three specimens. The sub-family Gerbillinae contains the African "and Asiatic Gerbils, in which the incisor teeth are grooved and the hind-feet elongated. The Common Gerbils of Africa are placed in two genera, Taterona and Gerbillus, the species of which are usually bright buff or sandy in colour above and pure white below. Arvicanthis testicularis (Sund.). Field Rat. One specimen. The common Field Rat of Africa, Arvicanthis testicularis^ is divisible into a very large number of local races, and possibly, when more material is available for examination, it will be found that the Arabian Field Rat is a pale race of the typical African Field Rat.
