. The specimen was partially fragmented upon collection and tears somewhat easily if torn perpendicular to the fibre tracts running through the sponge but otherwise is of firm consistency and resilient. The sponge is only slightly elastic. There is no special ectosome developed. The choanosome consists of ascending paucispicular tracts which are connected by single spicules.
