The well developed polyps arise on all sides of the stem and are very closely crowded in its 
upper portion, not sticking out at right angles to the stem, but growing upwards and tending 
to lie collapsed one on top of another. The polyps are large, up to 4.5 mm. in length. Their 
breadth measures about 1 mm., but the polyps are all compressed by preservation, and this 
measurement exceeds their true diameter. The polyp spicules are arranged in acute-angled 
chevron rows and the ‘points’ are quite distinct, consisting of smooth projecting spindles. These 
attain to 1.5 mm. in length, of which 0.3 mm. is a tuberculate portion and the remainder a 
smooth needle. 
All the remaining types of spicule also agree well with Kukenthal’s figure. They are 
mainly bent spindles, covered rather sparsely with simple prominences. Some indeed are pract¬ 
ically smooth. In the coenenchyma are also found some rather irregular forms derived from the 
spindle type, including one or two forked forms approaching a triradiate. 
The colour in alcohol is greyish-white with colourless spicules.

A strong colony, somewhat bushy in its branching, rising to a height of 10 cm., agrees 
in all respects with previous descriptions. 
Previously recorded by Nutting from Station 260, also recorded by Thomson and 
Henderson, from Indian Ocean, Trincomalee, and by Hiles from Funafuti, Barbados, and Azores. 
3. Acanthogorgia striata Nutting.

A broken colony, with a golden amber axis, thickly beset with polyps on its upper 
portion, closely resembles A. striata Nutting and also A. horrida Studer. It rises to a height 
of 10.5 cm., and the polyp-bearing terminal portion has a breadth of 7 mm. The long spicules 
that project at the top of the calyx have smooth spines arising at an angle from the much 
tuberculated basal portion. No longitudinal striation was seen, but there are chevron rows on 
the wall of the calyx. There does not seem to be much difference between A. striata Nutting 
and A. horrida Studer. A fragment from Station 251 seemed to be referable to the same 
species, but no spicules were boiled out. 
Previously recorded from Stations 117 and 253.
