Original Description
Outer shell thorny, thick walled, with irregular network; pores roundish, of unequal size, so irregularly distributed in polygonal groups that in every group two to six pores (commonly three to four) are near together; the groups are separated by broader bars. On the half equator six to eight groups and eighteen to twenty-four pores. Proportion of the longer axis to the shorter = 6: 5. Shorter axis equals twice the diameter of the inner ellipsoidal shell. Polar spines three-sided pyramidal, about as long as the equatorial axis, as broad at the base as a group of pores.
Size: Major axis of the cortical shell 0.12, minor axis 0.1; pores 0.004 to 0.012, bars 0.003; length of the polar spines 0.1, basal breadth 0.03.
Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Lithatractus gamoporus under the subgeneric name Lithatractium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
