(Fig. 49) The specimen consists of two stems joined at the base, successively ramifying. The stems are about 4 mm in diameter; the numerous branches, rather flattened, are 3-4 mm thick, often anastomosing. The surface is minutely hispid. The con- sistency is resilient and very flexible.

The specimen is about 15 cm high; the colour in life was orange-yellow (, more intense). Spicules. 1) Styles of the main skeleton measuring up to 220 x 6 [im. 2) Styles of the main skeleton close to the base of attachment up to 270 X 11 [im. They are faintly, asymmetrically tylote. 3) Styles hispidating measuring less than 1000 [im. 4) Acanthostyles measuring 120-150 [im. They have few and feeble spines, and are very rare even at the base of the stem. Remarks. In aspect and spiculation this specimen agrees closely with those I described from the Bay of Naples (1978: 42). Ab- normal growths as figured by Burton (1930: Fig. 1, B, C, D) often occur, but they do not seem to suggest the way the acanthostyles have originated. A few styles with regular smooth base and a few feeble spines do, however, appear as a transition to the typical Fig. 49 - Etidectyon delaubtnfelsi, specimen FI'\363. Scale: 3 cm. Annali Mus. Civ.
