palps are леьу thick and plump and end in quite a short filament. 

 Each of the tentacular cirri ends with a filament which is almost 

 a third part of the whole length of the cirrus. Antennae and tenta- 

 cular cirri are densely beset with large, thread-shaped papillae, each 

 of which is slightly swollen at the tip. 



The few elytra present are regularly reniform; their surface is 

 beset with rather large, head-shaped bodies, distributed in the fol- 

 lowing manner: The largest form a dense group on the hindmost 

 lobe of the scale. They are here so dense that they almost touch 

 one ariother. There is also a dense row along the whole outer 

 margin of the scale, the hindmost bodies in which are the largest, 

 becoming successiл'ely smaller towards the front end of scale. On the 

 remaining part of the surface of the scale the bodies are to some 

 extent ел^еп1у distributed; they are largest nearest to the outer margin 

 of the scale and become gradually smaller in towards the middle, 

 until those towards the inner margin are quite small. — Examining 

 these head-shaped bodies under a higher magnification we find, that 

 they are more or less globular and attached to the surface of the 

 scale by a short, thick neck. They are beset with conical prominen- 

 ces, which are nowhere pointed however, but everywhere abruptly 

 truncated. How far these prominences have originally been true 

 spines, is difficult to determine with certainty ; if so, they have every- 

 where been broken off in the elytra present, as they do not run out 

 to a point at any place ; there is one feature, however, which might 

 indicate that they are not broken or rubbed spines, namely, that in 

 the outermost end of several of these prominences there is a hook, 

 by which the point becomes slightly double. This condition recalls 

 the manner in which the small bodies end in Nijchia Amondseni 

 Mgrn. (Malmgren 1867, T. I, fig. 4E). hi other words, the point of 

 the prominences mentioned does not resemble a broken surface (see 

 fig. 3). 



The parapodium is low, the notopodial part being very little 

 prominent; the acicles lie close to one another and are comparatively 

 heavy in their proximal half; the cirri are short and beset with 

 papillae. — The ventral bristles have no tooth under the point, with 

 exception of some few — probably only two on the whole — nearest 

 the dorsum, which run out into a straight point; the end-leaf of 

 these is also rather different in form from the remaining ventral 

 bristles, being much longer and narrower (fig. 29). The central, ventral 

 bristles have a rather long, slightly bent point; where the tooth- 

 equipment of the end-leaf begins, there is uppermost a single tooth 

 or a couple of single, large, pointed teeth; just under these begin the 

 usual transverse rows of spines, which decrease more or less evenly
