ler, who found the species on the eastern coast of Africa, at 

 AnjLjra Pequena.* There are sHght differences in the figure of 

 the hook, to which the Austrian author gives transverse striae 

 in the distal region. Such, however, may be due to age or 

 local variation. 



Flabelligera marenzelleri, n.s. (an var. affinis.). 



Collected between tide-marks at St. James, False Bay, South 

 Africa. 



Procured along with Flabclligcui Itictator, Stimpson, from 

 which it is readily distinguished by its smooth body, the 

 presence of a membrane between the hooks, and the flattening 

 of the bristles to the sides of the body, apparently by a similar 

 gelatinous membrane. On the whole, however, it has a less 

 gelatinous aspect than such as Flabelligera affinis. 



The frontal bristles, in general aspect, resemble those of 

 Flabelligeta affinis, though minute examination shows that the 

 former are darker yellow, and that the segments are shorter. 

 No appreciable distinction could be drawn between the 

 elongated filaments, with their characteristic terminal enlarge- 

 ments. The tentacles and branchiae are similar. 



The fusiform body is more consistent than that of Flabelligera 

 affinis, and retains its straight outline, the convex dorsum being 

 covered by a glistening cuticle. The dorsal area is large, since 

 the lateral rows of bristles and hooks are carried far down- 

 wards, thus encroaching on the ventral area. 



The dorsal bristles are shorter, stouter, and duskier in hue 

 than those of Flabelligera affinis, and the transverse bars seem 

 to be rather closer. In the British form, these bristles taper to 

 a more slender elongated tip^followed by the long papillae. 

 The latter appeared to agree. 



The long golden hooks are arranged, for the most part, 

 singly, along the sides of the ventral surface, and have, about 

 the commencement of the distal third, a curve backward. 

 Distally, the shaft joins the flattened sickle-shaped tip (Plate 

 111., tig. 26), which dilates at its commencement, and ends in 

 a sharp strongly curved brownish claw. The internal striations 

 nearly correspond with those in the British species, indeed, it 

 is hard to draw a distinction between the two. The South 

 African has, apparently, a more brittle nature, since a separation 

 often occurred at the transverse segments, is darker (as a trans-
