to six. The Cape-specimens possess at least twenty to twenty five 
of these frills, the distal ones being situated close to one another 
below the tip of the bristles. Similar bristles were observed in the dorsal 
lobe of the foot in a specimen of Scalisetosus, collected by the Siboga- 
expedition at Station 260 '). 
The four (two on each side) small papillae, observed by Fauvel near 
the base of the exterior large papillae, at the entrance of the proboscis, 
of Scalis. assimilis, are also to be seen in Scalis. pellucidus °). 
Lagisca extenuata (Gr.) 
In Table bay several individuals of a Harmothoid-worm were collected, 
which in the structure of the head and the appearance of the scales and 
bristles-much agree with Lagisca extenuata, a common form on the coast 
of Europe and already mentioned from Simonstown by Ehlers”). The 
ventral bristles in the Cape-specimens however somewhat differ from the 
description and the figures, published by Me Intosh *). Whereas in the 
Cape worms the short dilated distal part of the ventral bristles ends in 
a hook-like tip, provided with a rather acute tooth below it, like as in 
Lagisca jeffreysii *) and Parmenis ljungmanni °), according to Me Intosh 
the ventral bristles in the British specimens usually are characterised by 
a very long, spinous, distal region and by the absence of a secondary 
process at the short, bare tip. Von Marenzeller ') however, who published 
a detailed account of Lag. extenuata, states that in the Mediterranean 
specimens the neuropodial bristles mostly are bidentate and that only a 
few of those, which are situated ventrally, have a simple, undivided tip. 
It may be suggested, that the Cape-worms, referred by Willey to a 
new species, Parmenis capensis *), also ought to be identified with Lag. 
extenuata, the scales and bristles quite resembling those of the last named 
species. However the lateral antennae in Parm. capensis appear to be 
much shorter than in Lag. extenuata. 
Harmothoé dictyophora Gr. 
Three specimens were captured in the neighbourhood of Durban (Bluff).
