On ornithodoros graingeri N.S.P., a tick from caves in Kenya.

Abstract

In April 1950, numerous ticks of the genus Ornithodoros were found in two coral caves, several hundred yards from the sea, near Diani about 20 miles south of Mombasa. Most of the ticks were found in the larger cave, which was irregular in shape, about 42 ft. long, and from 2 to 7 ft. high. Some of the ticks were crawling on the fine brown earth which covered the floors and others were just below the surface; none were seen on the walls.
