Title: Karyokinesis and cytokinesis in the maturation, fertilization and cleavage of Crepidula and other Gastropoda.
Description: Philadelphia, PA, University of Philadelphia, 1902. Large 4to (34.4 x 27,2 cm). Title page, 122 pp.; Six chromolithographed plates with explanatory text leaves. Original printed wrappers. Printed errata leaf losely inserted. = A rarely-seen work on the early developmental stages in gastropods, in particular in the genus Crepidula, written by the American biologist and malacologist Edwin Grant Conklin (1863-1952). Later, he wrote more studies based on Crepidula anatomy and ontology. This early work, however, is the rarest, being a reprint from the Journal of the Academy of Sciences of Philadelphia, second Series, Vol. XII Part I. Uncut. Wrappers chipped and frayed at edges; a water stain on the front wrapper and first six text leaves (rapidly diminishing). Otherwise a very good, unmarked copy.
