| two new species of the genus sitana cuvier, 1829 (reptilia: agamidae) from sri lanka, including a taxonomic revision of the indian sitana species. | the genus sitana was described by cuvier (1829) on the basis of a single species, s. ponticeriana. the secondly described, sitana minor günther, 1864, is identical to s. ponticeriana cuvier, 1829, and should be considered as a junior objective synonym of the latter. the syntypes of s. deccanensis jerdon, 1870 have been rediscovered, misplaced among the syntypes of s. minor (sensu boulenger 1885) at the natural history museum (london) and the former taxon is here recognised as a valid species and ... | 2015 | 25662111 |
| light and electron microscopic observations of fabrication, release, and fate of biphasic secretion granules produced by epididymal epithelial principal cells of the fan-throated lizard sitana ponticeriana cuvier. | the epididymis of the fan-throated lizard sitana ponticeriana was examined with light and transmission electron microscopy to understand the cellular mechanisms of fabrication of secretion granules in epithelial principal cells, granule release into the lumen, and the fate of the dense structured granules after reaching the lumen. principal cells of the ductus epididymis, except at the cauda, secrete electron-dense biphasic granules copiously, which decrease in abundance from the initial segment ... | 2006 | 16526053 |
| ultrastructural evidence for secretion from the epithelium of ampulla ductus deferentis of the fan-throated lizard sitana ponticeriana cuvier. | among reptiles, an ampulla ductus deferentis has been reported only in squamata. fairly detailed studies are available only for two species, the lizard calotes versicolor (fam: agamidae) and the snake seminatrix pygaea (fam: colubridae). the light microscopic study on c. versicolor revealed the ampulla to be a prominent organ, whereas the light and transmission electron microscopic study in s. pygaea revealed it to be discernable only in histological preparations. further, the epithelium of the ... | 2005 | 16127705 |
