CLATHRINA PROCUMBENS ( VON LENDENFELD, 1885) View in CoL
Original type: Ascetta procumbens von Lendenfeld, 1885
Type locality: East coast ( Port Jackson ) and South coast (Port Phillip, VIC) of Australia .
Type: BMNH 1886.6 .7.3 (lectotype /alcohol). South coast of Australia (Port Phillip, VIC) , BMNH 1886.6.7.1–2 (syntypes /alcohol). East Coast of Australia (Port Jackson). Both from the Dr von Lendenfeld Collection .
Citations: Dendy (1891); Burton (1963).
The specimens named as the syntypes are typical clathrinas. One of them is attached to a Mytilus shell.
Colour: Preserved specimens white to light yellow.
Description: Cormus formed of irregular and loosely anastomosed tubes with variable diameters. The surface of these tubes is smooth. In some places, tubes attach to the substrate to anchor the sponge. At the apical region there are water-collecting tubes converging into the oscula. The skeleton has no special organization ( Fig. 27A View Figure 27 ), comprising equiangular and equiradiate triactines ( Fig. 27B View Figure 27 ). Actines are conical with sharp tips. The size of spicules is quite uniform, but there are also some small young spicules.
Remarks: Ascetta (Clathrina) procumbens was considered a synonym of Leucosolenia protogenes ( Ascetta primordialis var. protogenes Haeckel, 1872 ) by Dendy (1891).This synonym was confirmed by Burton (1963), and no one has resurrected this species since.
Three types of this species are deposited in BMNH: two syntypes and a lectotype. When we examined these specimens, we finally understood the problem involving C. procumbens .
As Dendy wrote: ‘one of his (Lendenfeld) figures (Pl. LXI, Fig. 1a View Figure 1 ) agrees with this description (the original description of C. procumbens ), but three others, said to be of the same species (Pl. LXI, Figs 1b, c,d View Figure 1 ), represent a massive, lobose sponge of very different appearance. The fragment also, sent to me from the British Museum, is evidently a portion of a massive sponge’. Dendy was right about this, but not about the synonymy of C. procumbens and L. protogenes . The specimen he agreed matched the description made by von Lendenfeld is the one
