BAYLIS' (1926) material of R. (R.) insignis from Ducula badia that the present writerassigns the specimens from Rennell Island and the British Solomons to this species.Raillietina (R.) insignis has also been recorded from Vinago delandii in Africa byBAYLIS (1926) and by BAER (1933). A re-examination of BAYLIS' African materialreveals the presence of 25-30 testes, while BAER states that his material possesses 20-25testes. These testes are contiguous posteriorly to the female complex in the latermature segments - a condition not observed in the material describedabove. It seemstherefore probable that the specimens from Vinago are not identical with those fromDucula.REFERENCESBAER, J.
