Original description Differs from U. naresianus in the configuration of the posterior end of the test; the periproct is just above the ambitus, rather sunken, the test produced beyond it, both above and below. There is a distinct subanal fasciole. Otherwise it agrees with U. naresianus in form and structure of the test. The globiferous pedicellariae afford a very distinct character; the valves end in a single long tooth, whereas in U. naresianus there are 9 long slender, gracefully curved teeth, surrounding a terminal opening.
