The trunk musculature of caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 1980AbstractDescriptions of the trunk musculature of six species representing sex genera and five families of caecilians reveal considerable variation, which may be useful in future systematic studies. The muscle units of the external muscular sheath (M. dorsalis trunci, M.

Abstract Caecilians are a monophyletic group of elongate, snakeor wormlike amphibians lacking all trace of limbs and girdles, and with tails reduced or absent (Fig. 1). 7ey are one of the three orders of the extant Lissamphibia, the Gymnophiona (naked snakes), and are most likely the closest relatives of the more familiar frogs and ...

Ultrastructure of the mature spermatozoa of caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 2003AbstractThe spermatozoa of Gymnophiona show the following autapomorphies: 1) penetration of the distal centriole by the axial fiber; 2) presence of an acrosomal baseplate; 3) presence of an acrosome seat (flattened apical end of nucleus); and 4) absence of juxta‐axonemal fibers.

Tooth crown morphology in caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 1979AbstractThe morphology of tooth crowns is variable inter‐specifically among caecilians. Cusp number and shape, crown dimensions, and crown curvature characterize various species and have both functional and phylogenetic implications. Ichthyophis, Uraeotyphlus, Hypogeophis, and Geotrypetes have bicuspid teeth; Dermophis, Gymnopis, Caecilia, and ...

Visual projections in larval Ichthyophis kohtaoensis (Amphibia: gymnophiona)
Developmental Brain Research, 1985The visual projection patterns of retinal efferents were studied in larval Ichthyophis kohtaoensis by means of anterogradely transported HRP. Our results show in all larvae a projection contralateral to a thalamic terminal field, a pretectal terminal field, and a basal optic neuropil, but only a sparse innervation of the contralateral tectum.

Electrophoretic patterns of certain proteins in caecilians (amphibia: gymnophiona)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. A maximum of 15 loci from five genera of caecilians (Amphibia: Gymnophiona or Apoda) were examined. Species include Ichthyophis glutinosus, Geotrypetes seraphini, Caecilia occidentalis, Gymnopis multiplicata , and Dermophis mexicanus . 2. 2.

Comparative morphology of caecilian sperm (Amphibia: Gymnophiona)
Journal of Morphology, 1994AbstractThe morphology of mature sperm from the testes of 22 genera and 29 species representing all five families of caecilians (Amphibia: Gymnophiona) was examined at the light microscope level in order to: (1) determine the effectiveness of silver‐staining techniques on long‐preserved, rare material, (2) assess the comparative morphology of sperm ...
