Show 1905.] ON BATS OF THE GENUS RHINOLOPHITS. 75 3. On some Bats of the Grenus R l i i n o l o p l m s , with Remarks on their Mutual Affinities, and Descriptions of Twenty-six new Forms. By K n u d A n d e r s e n * . [Received May 12, 1905.] (Plates III. & IY .f and Text-figure 22.) The present paper is, chiefly, an attempt to disentangle some of the more complicated groups of Eastern Rhinolophi, to make out the probable interrelations of the species, and to describe the many new, imperfectly known, or hitherto confused forms. I have appended some general remarks on the affinities of the Ethiopian and Western Palsearctic species. The material placed at my disposal has been more extensive than that of previous writers on these Bats, namely, Prof. Peters (1871) and Dr. Dobson (1878); and I have approached the subject from a different point of view, basing the diagnoses of the primary groups, and, where possible, of the species and subspecies too, not on external and dental characters alone, but also on important differences in the skulls. This may account, partly at least, for the essentially different conclusions on many points at which I have arrived. On the other hand, the following pages afford ample proof that my material has not been complete enough to enable me to venture an answer on all the difficult questions, taxonomic or phylogenetic, that occurred to me during my work. I shall feel satisfied if my paper is considered of some use as a basis for further investigations. I owe my sincere thanks to Mr. Oldfield Thomas for entrusting me with a revision of these Bats, for giving me unlimited access to the recently acquired, still unregistered specimens in the British Museum, especially those of the large and important " Tomes Collection," and also for having favoured me with much valuable information during the progress of my work. I also have to acknowledge the kind assistance of Mr. Gerrit S. Miller, Jr., who sent me for inspection almost all the Indo- Malayan Rhinoloplii preserved in the United States National Museum, including many new and interesting forms, part of which will be dealt with below. For the loan of specimens for comparison, or for information on examples preserved in Continental Museums, I am indebted to Geheimrath Prof. Dr. Elders, Gottingen ; Prof. Matschie, Berlin ; Prof. Dr. Kurt Lampert, Stuttgart; M. Ch. Mottaz, Geneva; M. A. Menegaux, Paris; and Prof. A. Cabrera Latorre, Madrid. I . T h e R hijvolophus s im p l e x G r o u p . Diagnosis. Basioccipital, between cochlea?, not unusually narrowed.
