Chytra kirki is a species of tropical freshwater snail with an operculum, aquatic gastropod mollusk in the family Paludomidae. [1]
Chytra kirki is the only species in the genus Chytra. [5]
The specific name kirki is in honor of explorer John Kirk (1832-1922), who has donated various other specimen of snails (not this species) to the Natural History Museum. [6]
This species is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. [1] The type locality is Lake Tanganyika. [4]
The shell is solid, trochiform and dirty whitish in color. [6] The spire is acutely conical. [6] The shell has 6 or 7 feebly concave whorls. [6] They are bearing arcuate and flexuous lines of growth and six or seven granulous lirae, whereof that immediately above the suture is the largest. [6] The body whorl is acutely angular at the periphery, encircled by two subequal granular ridges. [6] The base is concave near the circumference, then slightly convex, concentrically granosely ridged. [6] The ridges nearest the umbilicus are coarser than the others, and also arcuately radiately striated. [6] The shell has deep and narrow umbilicus. [6]
The aperture is irregularly subcircular and whitish. [6] The outer lip (viewed laterally) is obliquely incurved. [6] Basal and columellar margins are forming one strongly arcuate line joined above to the extremity of the labrum by a thickish callosity. [6]
The width of the shell is 19 mm. [5] The height of the shell is 15 mm. [5]

Its natural habitat is freshwater lakes. [1] It is widespread [5] species in the Lake Tanganyika, but its distribution is patchy and with low numbers of snails. [1] It lives on the mud with much organic material in depths 10–20 meters. [1] [5] There is possibility that it can live in depths up to 80 m. [1] [5]
