NOTES ON JAPANESE, INDOPACIFIC, AND AMERICAN PYRAMIDELLID^. By William Healey Dall, Curator, Division of Mollmks, AND Paul Bartsch, Assistant Curator, Division of MoUusks. JIm^ setter ng™ater,al for the monograph of Pacific coast Pyra-midel ,d» on wh.ch the authors of the present paper have been for some time engaged application for material for study was made to the Komgl,che Zoolog.sehe Museum in Berlin, where the types of many of the species treated of in the second edition of the Conchylien uabmet were known to be preserved. Through the kind intervention of the late Prof. Dr. Eduard von Martens, in charge of the conehological collection of the Berlin Museum the entire series of their Pyramidellid*, including numerous types' was lent to the U. S. National Museum for study^ This series con tamed material fi-om many sources, of which the most important were the collections of the late Henry and Arthur Adams, of Pastel of Dunker, and Hilgendorf. Numerous specimens of species inade-quately described by Arthur Adams from Japan were among the most valuable tor our work, and the importance of accurately figuring and : adequately dcsc.ribing them was evident, as, until such descriptions were made pubhc, no small number of species of the Japanese fauna must remain doubtful. Though mostly small and to many students uninteresting, the Pyra-midellida^^ exist in much larger numbers than is generally realized lo obtain a satisfactory view of their specific characters, in most cases the species must be studied under the microscope, and to get accurate figures of these minute creatures enlarged photographs or camera lucida drawings are essential. The difficultv of obtainino-these in the present instance was much enhanced bv the death of ou" chief draftsman and faithful collaborator, the latc^ Dr. J. C. McConnell, for Proceedings U. S. National Museum, Vol. XXX-No. 1452. Proc. N. M. vol. XXX— 06 21 3.,,
