No. 5. — Zoological Results of a Fifth Expedition to Fast Africa V Chilopoda ( Myriopoda) By R. F. Lawrence Natal Museum, Pietermaritzburg, South Africa CONTENTS Page Introduction 409 Systematic Discussion 412 INTRODUCTION The material dealt with in this paper consists not only of the Chilopoda collected by Arthur Loveridge during his expedition to Nyasaland ( 1948-1 949) * but includes the bulk of the material collected during his earlier visits to Equatorial East Africa at various times during the years 1915-1939. The dates of these expeditions are as follows: 1915-1919. "German East Africa" and Mozambique. 1920-1923. Kenya Colony and Tanganyika Territory. 1926-1927. Chiefly the Uluguru and Usambara Mountains, Tanganyika. 1929-1930. Tanganyika Territory; Northern Rhodesia and Uganda. 1933-1934. Debasien Mountain, Uganda to the coastlands of Kenya. 1938-1939. Uganda; eastern Belgian Congo; coastlands of Tanganyika. 1948-1949. Nyasaland and near Tete, Zambezi River, Mozambique. The 1915-1919 collections were submitted to the late Mr. Stanley Hirst at the British Museum in 1920, and remained there until 1924. Mr. Hirst identified the centipedes only, and as he could hold out no hopes of the millipedes being determined, they were taken to the United States in 1924. These earlier collections, together with the 1926-1927 material, were shipped in 1927 to Dr. Carl in Switzerland, where they remained for five years without any identifications as to species having been 1 Made possible by a generous grant from the Penrose Fund of the American Philosophical Society.
