Subcortical triactines: Pseudosagittal. Actines are conical and sharp. The longest paired actine is straight (paired 1), while the shortest one is curved (paired 2). The unpaired actine is the shortest actine. Like in all pseudosagittal spicules, the paired 2 actine and the unpaired actine support the cortex, while the paired 1 actine points centripetally (

of spicules forming the tubar skeleton: triactines and prochiacts. He considered that the former had paired actines of unequal length and were present in both subcortical and subatrial skeletons. On the other hand, prochiacts had the two paired actines of equal length and were the most abundant spicules in the tubar skeleton, being found mainly in the subatrial skeleton. We interpret that what Row called triactines of the tubar skeleton are pseudosagittal triactines, while what he called prochiacts are in fact the subatrial triactines. Independently of a possible misunderstanding on the spicules categories, our specimens are very similar to
