HOLOTYPE. — New Caledonian Slope ( MNHN DCL 3541 About MNHN ).

MATERIAL EXAMINED (see Table 1). — Introuvable, 562-576 m ( QM G318597).

DESCRIPTION

Growth form

Columnar, erect, cylindrical sponges with an axial cavity, which extends to half the height of the sponge and ends at the conical summit. The summit may bear a single oscule as terminal extension of the axial cavity or may be closed. The examined specimen has an osculum and is about 3 cm high. Colour

Beige with yellow and pinkish areas in etoh.

Oscules

One large apical oscule; ostia 67-83 µm.

Texture

Hard, stony.

Surface ornamentation

Smooth.

Ectosomal skeleton

Ectosomal skeleton contains a layer of very abundant smooth dichotriaenes perpendicular to the surface and abundant microscleres. Microscleres at the surface are numerous, forming a crust and consist of microspinose blunt spiraster streptasters.

Choanosomal skeleton

Skeleton consists of strongly tuberculated, irregular dicranoclones, producing a very dense structure. Within the choanosome microscleres are long pointed spirasters.

Megascleres

Dicranoclone desmas thick, mushroom-shaped tubercules are slightly subdivided into smaller very low callosities and sometimes appear smooth: 650-750 µm/70-100 µm.

Dichotriaenes smooth; conical, straight rhabdome and cladome: 395-617 µm long × 377- 509 µm (diameter of the cladome).

Oxeas large, protruding from the surface, but invariably broken.

Anisoxeas: 169-466 × 3.86-4.66 µm.

Microscleres

Massive (rhabd-like) spirasters: 15.6-19.1 × 7.45- 9.07 µm.

Spirasters with slender arms: 29.3-35.1 × 15.7- 20.1 µm.

REMARKS

This new material conforms closely to the holotype, with the exception of having slightly smaller microscleres.
