Clathrina contorta

sensu
Jenkin 1908
Jenkin (1908: 437)
described three specimens of a pure white sponge from Zanzibar with irregularly anastomosed tubuli under this name.
Leucosolenia contorta
(
Bowerbank, 1866
)
from Northeast European waters has a checkered history (cf.
Minchin 1905
;
Klautau & Valentine 2003
) with the current not well-established conclusion that it is a senior synonym of
Ascetta spinosa
Von Lendenfeld, 1891
described from the Adriatic and now assigned to the genus
Ascandra
as
Ascandra contorta
(see Klautau
et al.
2016). How
Jenkin (1908)
came to consider his specimens to be a member of this species from Europe is not quite clear. The triactines and basal actines of the tetractines were 80–150
x 10–12
µm, the apical actines of the tetractines were 50–
65 x 5–7
µm. It is likely, but not certainly a species of
Ernstia
and its pure white color may indicate it is as yet undescribed.
