Descriptions of Earthworms

My colleague Mr. J. Büttikofer, at this moment making part of an expedition in West-Borneo, collected on the Goenong Kenepai a large earthworm, belonging to the family of the Moniligastridae. Though our knowledge of the organisation of this interesting group much increased in the last years thanks to the careful investigations of Rosa, Beddard and Benham, there yet remain some points in their structure upon which further information is desirable; I will therefore not defer any longer to give a description of this new species, for which I propose the name of Moniligaster coeruleus.
