XXXVIII. ONYCHOPHORA. By Stanley Kemp, B.A., Assistant Superintendent , Indian Museum. (Plates xxxiv xxxvii.) Introduction. The discovery of a species of Peripatus on the north-east frontier of India at the foot of the Eastern Himala^^as, must be reckoned as one of the most interesting zoological results of the Abor expedition. The Abor country lies far to the north of the nearest point at which specimens have previously been obtained, and no member of the group was hitherto known to occur within the limits of the Indian Empire. The single species found is, moreover, highly peculiar in many respects and, though showing traces of alliance with Eo peripatus, which occurs in Sumatra and the Malay Peninsula, differs sufficiently in regard to the characters employed by Bouvier, Evans and other authors to entitle it to separate generic rank ; in the absence of an}^ external trace of eyes it appears to be unique. In describing this form it is not my intention to deal at length with the status of the different genera of Onychophora which have been proposed, or to support either of the systems of nomen-clature upheld respectively by M. E. L. Bouvier ajid the late Dr.
