Fine structure of the abdominal epidermis of the adult mudpuppy, Necturus maculosus (Rafinesque)
The ventral epidermis of adult Necturus maculosus has been studied using electron and light microscopy and appears to be involved in the secretion of vesicular contents onto the outermost surface of the epithelium.
Replacement of the Larval Basement Lamella by Adult-Type Basement Membrane in Anuran Skin during Metamorphosis
OUI concern in this paper will be the normal changes that transform the thin larval dermis of the frog Ranu pipiens into the thickened dermal skin of the adult and the development of the f)awmerit membrane of adult skin.
A Review of Pertinent Literature on the Thyroid of Urodela, with Special Reference to Necturus
The present review concerns, primarily, those papers dealing with the thyroid gland of N ecturus; as also, secondarily, some papers treating of other animals, which were important in the development of the present understanding of thyroid function in Urodela.
Form and Function of the skin glands in the Himalayan newt Tylototriton verrucosus
The skin in the Himalayan newt T. verrucosus displays one mucus- and two poison gland types enwrapped by a myoepithelial sheath that is more prominently developed in the granular glands compared to the mucous glands.
Histology and ultrastructure of the caudal courtship glands of the red‐backed salamander, Plethodon cinereus (Amphibia: Plethodontidae)
The first study on the fine structure and seasonal variation of CCGs is presented, using the plethodontid Plethodon cinereus, and the CCGs are similar histologically to sexually dimorphic skin glands described in some anurans, but more comparative work is needed.
New insights into vertebrate skin regeneration.
Lumbar glands in the frog genera Pleurodema and Somuncuria (Anura: Leiuperidae): Histological and histochemical perspectives
Skin of LGs presents characteristic features as the interruption of the Eberth–Katschenko layer and the presence of a differentiated type of gland only observed in macrogland and not previously described for Pleurodema or Somuncuria; this is termed lumbar serous gland.
Cloacae, Cloacal Glands and Female Sperm Storage in Giant Salamanders
Information from a number of separate studies on histology of the cloaca and cloacal glands and ultrastructure of sperm storage, when it occurs, in the giant salamanders is brought together and summarized.


In attempting to explain the pigmentation of the salamander, Salamiandra macu/ata, Fischel' found that the temperature to which the animals were subjected was an important factor and it was observed that the larvae of thesalamander which developed in warm water were of a lighter color than those which development in cold water.
