The Morphology of the Seminal Vesicles, Accessory Glands, and the Ejaculatory Canal of Melanoplus Differentialis (Thomas) and an External Morphological and a Histological Study of the Seminal Vesicles, Accessory Glands, and Ejaculatory Canal of this Grasshopper

Abstract

The purpose of this thesis is to record the results of an investigation, by the writer, upon the reproductive system of Melanoplus differentialis (Thomas) with special emphasis placed upon the external morphology and the histological study of the seminal vesicles, accessory glands, and the ejaculatory duct; and also to record conclusions as to the probable function of these organs
