Type material: Type material is not known. Type locality: Haeckel based his description on one specimen from Norway and one from Greenland * without designating the type material % Rapp 2015). Material studied: Altogether 177 specimens. Molecular data— 177 specimens * external morphology— 177 specimens * skeleton organization— two specimens %WS11650* WS11653)* spicules %SEM)— five specimens %WS11649* WS116450* WS11653* WS11657* WS11658)* cytology % TEM)— six specimens %WS11631* WS11632* WS11634* WS11635* WS11636* WS11637) %Supporting Information* Table S1). External morphology: Cormus formed by basal reticulation of tubes* from which erect oscular tubes and long diverticula arising. Sponge bear from one to multiple* slightly curved oscular tubes* with or without short* lateral diverticula in the basal part. Oscular tubes gradually narrow to oscular rim* possessing short* spicular crown % Fig. 7A * B). Surface minutely hispid or echinate. Coloration of living and preserved specimens greyish white % Fig. 7A). Spicules: Diactines % Fig. 8A * B). Curved* lanceolate diactines* mean length 179 µm* mean width 6 µm % Table 5)* slightly curved with lanceolate outer tip* variable in size* smooth or with few small spines at lanceolate tip % Fig. 8B). Triactines % Fig. 8D). T-shaped sagittal %mean angle 142.9°)* unpaired actines usually shorter than paired %mean length: 70.5 µm—unpaired* 82.7 µm—paired) % Table 5)* rarely equal. Actines equal in width %mean width: 6.5 µm—unpaired* 6.5 µm—paired) % Table 5). Tetractines % Fig. 8C). T-shaped sagittal %mean angle 151.4 °)* unpaired actines shorter than paired or equal ...
