Distal Urogenital Anatomy Of Male Southern Coal Skinks, Plestiodon Anthracinus Pluvialis (Reptilia: Scincidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I investigated the morphology and histology of the distal urogenital anatomy of male southern coal skinks (Plestiodon anthracinus pluvialis) from reproductively active individuals collected in Arkansas in order to provide comparative information with recent studies on squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts in this skink, which included portions of the ductus deferens, the ampulla ductus deferentis, the sexual segment of the kidney, the ureter and collecting ducts, as well as aspects of the urodaeal chamber and urogenital papillae. I found a much reduced ampulla ductus deferentis comprising only 0.7 …

Germinal Epithelium Cytology During Spermatogenesis In The Alligator Snapping Turtle, Macrochelys Temminckii (Reptilia: Chelydridae), Stanley E. Trauth, Kevin M. Gribbins
Journal of the Arkansas Academy of Science
We investigated the cytology of the seminiferous epithelia of the Alligator Snapping Turtle (Macrochelys temminckii). Spermatogenic and regressed testes were assessed from 2 adult individuals collected in Arkansas in May and September of 1993. Specifically, we focused on the cellular phases of germ cell development and maturation. The germ cell morphology and developmental strategy within the germinal epithelium of M. temminckii appear similar to that of other genera of turtles previously studied. Interestingly, mitotic, meiotic, and spermiogeneic cells are nearly identical to that of other turtles studied based on light microscopy. There are also 6 recognizable steps to …
