CLATHRINA PANIS ( HAECKEL, 1872)

Original name: Ascandra panis Haeckel, 1872

Type locality: Atlantic coast of North America (Florida, Agassiz ) .

Type: PMJ. Inv. Nr. Porif. 152 (syntype /alcohol) . Florida, North America .

Citations: Thacker (1908); Dendy & Row (1913); Tanita (1942).

Colour: Preserved specimen is white.

Description: Almost spherical, formed of irregular and loosely anastomosed tubes. Sediment is present inside the cormus. A large tube (pseudoatrium) can also be found inside the cormus.

Triactines ( Fig. 24A View Figure 24 ), tetractines ( Fig. 24B View Figure 24 ) and a few diactines form the skeleton. Triactines and tetractines are equiangular and equiradiate and their actines are conical and a little undulated, with sharp tips. The apical actine of the tetractines is a little shorter, thinner, conical, smooth and straight, and it is projected to the interior of the tubes. Tetractines are less abundant than triactines. There are very few diactines. They are fusiform and penetrate the surface of the sponge.
