and corals, combined with correct climatic conditions, are ad mirably suited to tick infestation (cf. page 145), but Duruma sandstones, grits of the karroo, and limestone and shale areas are less suitable. Many huts seem to have been infested by visitors traveling from infested areas with blankets (cf. pages 145 and 180) for social purposes, funerals, shopping, and during troop movements. One of the most interesting aspects of this study is the correlation of infestation with definite climatic conditions. The coastal area, with over fifty inches of rainfall annually and with average hut floor RH of 88% and temperature of 77.80F., is almost entirely devoid of ticks. Infested areas are those with thirty to fifty inches of rainfall annually and with hut floor RH aver. aging 83.3%, apparently the optimum for the tampan (consideration of ticks above the floor level, in niches with different RH, or seeking certain conditions with greater or lesser RH within the huts is not attempted). The tick-free hinterland receives about 35 inches of rainfall annually; here the hut floor RH is 79% and the average temperature 78.4°F. (cf. pages 137,156 and 157). Clearly, this study represents the first generalized attempt to correlate tick infestation with climatic factors and tribal customs and habits. The incidence of spirochete infected ticks is also noted. It should be of some significance to determine just how far ticks will endeavor to seek out niches with varying microclimates in an infested structure and what the optimum and threshold conditions are.

Summary: "Tick-borne relapsing fever, formerly common, has been eradicated in the Somaliland Protectorate by planned and systematic destruction of the vector, 0. moubata, by a programme of spraying of all human dwellings with a water dis persible preparation of gammexane (P.520). The last indigenous case was seen in September, 1952. It is considered that the danger of reintroduction of the disease is small as 0. moubata tend to pass their lives in or near their hatching placē, with little tendency for dissemination, so that they are unlikely to become reestablished in the settlements that have been cleared by spraying." Whether this surmise is sustained by future experience will be interesting to which for. 0. savignyi is considered of no epidemiological significance and the indoor and outdoor habitats of the two spe cies are strictly localized in Somaliland, except for the soil under one large shade tree in town, which yielded large numbers of 0. moubata. Persons sleeping under this tree contracted relāpsing fever from the bites of 0. moubata. ORNITHODOROS SAVIGNYI FRANCHINI (1927%). Ethiopia, common in eastern lowlands. reports from colony.
