Sexual Recognition in Adult Erythemis Simplicicollis (Odonata: Anisoptera) Andrew, Clifford G. This research was conducted primarily to determine if male dragonflies of the dimorphic species Erythemis simplicicollis reacted differently towards the different sexes, and, if so, to find out what sexual differences served as stimuli for the various behavioral patterns. Altogether thirty-five experiments were conducted in the marsh of Ebaugh Pond, Denison University, utilizing St. Quentin's fishing-line technique (1934) to simulate natural conditions. The experimentation involved altering the physical appearance of both live and dead dragonflies of both sexes and observing the reaction of free males towards these specimens. It was concluded that the visual recognition in this dimorphic species involved stimulation by perception of body coloration, and did not include any recognition of variation in flight pattern or any other subtle difference in behavior.

Diplocardia Varivesicula, a New Megascolecid Earthworm from Indiana (Oligochaeta) Murchie, William R. A new quadrithecate diplocardian earthworm, Diplocardia varivescula, is described from southern Indiana. The species shares some attributes with Diplocardia invecta and D. koebeli, both of which are known only from Mexico. The new species differs from known species in position of the seminal vesicles, variability of spermathecal pores, setal sculpturing, pattern of genital tumescences, and distribution.

Convex-Concave Landslopes : A Geometrical Study White, J. F. The geometry of convex-concave landslopes is described by empirical equations, so that shape, scale, and form elements may be compared numerically. Gradient-length relations determine intervals over which particular form elements exist, and over which particular equations apply. Three segments of slopes are defined, an upper convex element, a middle straight element, and a lower concave element, where the change in gradient with length is respectively positive, zero, and negative. The use of gradient data allows accurate definition of form elements and the intervals over which they exist. Use of profile data alone results in incorrect determination of form elements and inaccurate numerical description. The slopes studied occur in southwestern Ohio, have straight contours, and are developed on kames, end moraines, and shale hills. Numerical constants obtained from profile and gradient relations accurately describe each slope element. A middle straight element is demonstrated to exist, but is absent in 30 per cent of the slopes studied. Relationships among numerical constants and parent materials indicate highly similar geometric forms, apparently different only in scale. Persistence of equivalent form elements from long to short slopes implies that length of runoff is not the determining factor in shaping convex-concave profiles, and that the presence of the convex element does not depend on dominance of processes of creep over those of runoff.

A Second Experiment in Self-Instruction in General Biology Kormondy, Edward J. A study was made in 1964 of the effectiveness of college-level independent study of basic Mendelian genetics using a programed text as compared to a conventional text and both compared to traditional lecture-textbook approach. Covariance analysis of preand post-tests demonstrated a significant difference in mean gain scores of the programed text group over the other two; no significant difference was observed between the independent study-traditional text group and the lecture-text group, nor between freshmen and upperclassmen in any of the three groups.
