Median basal avicularium at bifurcation. Grooves into which mandibles fit are stippled, r. rootlet. known, this difference is probably not of systematic value. The distal wall of the fertile zooecium of A. gaussi commonly bears a few teeth directed towards the ovicell (Fig. 1 C), but they may be absent, or only represented by a single tooth. Such teeth have not been seen in A. nuda. From his description of the scutum, the spines and the ovicell it is clear that Hasenbank's material from Bouvet Island identified as A. nuda, belonged to A. gaussi. There is some variation in the size of the frontal avicularia of A. gaussi. This is most noticeable in the specimen from St. 167 which has some rather large ones. A fragment from St. 599 has no Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
