Monanchora laminachela sp. nov. (Fig. 6 a–d, Fig. 7 a–d) Material Holotype: USNM 1084240 (51° 31.491' N, 177° 57.506' W, South of Tanaga Island, 485 m depth, 0 2. 0 8. 2004). Paratype: USNM 1084241 (51° 31.491' N, 177° 57.506' W, South of Tanaga Island, 485 m depth, 0 2. 0 8. 2004). Description The two specimens collected are stalked sponges with subglobular bodies (Fig. 6 a), 9–10 cm in height, maximum diameter of the body 6 cm growing on a large boulder. The smooth stalk is about 4 cm long and 2–4 mm in diameter. The body has a corrugate surface in life (Fig. 6 a) which becomes conulose (Fig. 6 c) after freezing the specimen. The consistency is elastic but firm. Colour in life yellow, changing to orange brown after freezing (Figs. 6 a–c). Skeleton: The ectosomal skeleton consists of a thick membrane of tangential brushes of smaller styles, fairly dense, and many isochelae in between. The choanosomal architecture consists of thick, ascending polyspicular tracts of large, thick styles connected by shorter ... : Published as part of Lehnert, Helmut, Stone, Robert & Heimler, Wolfgang, 2006, New species of deep­sea demosponges (Porifera) from the Aleutian Islands (Alaska, USA), pp. 1-35 in Zootaxa 1250 on pages 10-13, DOI: 10.5281/zenodo.173010 ...
