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.

Retinal projections in the caecilian Ichthyophis kohtaoensis (Amphibia, Gymnophiona)
Cell and Tissue Research, 1985The retinal projections of the caecilian Ichthyophis kohtaoensis were investigated by anterograde transport of HRP. The optic tract forms two bundles in the diencephalon, a narrow medial bundle in the optic tectum, and a basal optic tract consisting of few fibres.

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 ...

The structural organization of the kidney ofTyphlonectes compressicaudus (Amphibia, Gymnophiona)
Anatomy and Embryology, 1986The structural organization of the kidney of Typhlonectes compressicaudus (Amphibia, Gymnophiona) was studied by light microscopic (LM) examination of serial paraffin and semithin Epon sections. The kidney is slender and quite long and has a mesonephric segmental construction; the excretory duct (Wolffian duct), running along the lateral side of the ...

Systematics of the caecilians (Amphibia: Gymnophiona)
1987Determining the higher level relationships of the modern amphibian order Gymnophiona (caecilians) poses a number of methodological problems. A cladistic methodology is outlined by which the phylogenetic relationships of this group can be determined objectively.

A nine-family classification of caecilians (Amphibia: Gymnophiona)
Zootaxa, 2011We propose a new family-level classification of caecilians that is based on current understanding of phylogenetic relationships and diversity. The 34 currently recognised genera of caecilians are diagnosed and partitioned into nine family-level taxa.
