The thumbs below are a top view of such a drum. Pic on top left shows the synthetic see through skin and countersunk bolts. To the right the same drum with the rim off. The metallic sound it emits is phenomenal, sharp highs, the brightest slaps, and surprisingly resonant lows. As far as I know, the proper term is Tarabooka.
Same story applies for some African and other ethic drums.
I simply call it a lap drum, because this is my favourite way of playing it. Visit my Lynx page for the URL to two of these. Too often I see westerners playing this drum sitting down with the body of the tarabooka held perpendicular between the legs, and the head facing straight up like a djembe. In this position one cannot produce those rhythms characteristic of the Middle East, since the hands strike down in a tone - tone fashion, and the use of the fingers impeded, thus the essence of the tarabooka is lost because the tarabooka is essentially a finger drum. There is nothing wrong in doing it that way, so long as it sounds good.
