The genus Allmaniclla was based by Mr Intosh upon the anterior fragment of a minute 

 worm, dredged by the Challenger Expedition off Setubal ; without giving a special diagnosis, the 

 author says : "it is characterised by its largc eyes, pecuHar shape of the head, and the remar- 

 quable structure of the ventral bristles, which show bifid points terminally, and then some distance 

 beneath another distinct point inaugurates the spinous rows." Farther on he states : "the in- 

 ferior setigerous lobe is produced into a long conical process, with the spine at the apex." 



I have some doubt that this genus was based upon specimens in a stade of sexual 

 malurity and belonging to Paralepidonotus.

At the above-named Station a Polynoid was found, that with regard to the shape of 

 its head and its large eyes much agrees with Allmaniella sehióaletisis Mc Int., dredged by 

 the Challenger Expedition off Setubal in a depth of 470.fathoms. It has a length of 30 mm. 

 and consists of 36 segments ; on the dorsal side of each segment there occurs a transverse, 

 oblong elliptical spot of brown colour preceded and succeeded by a linear one. The prosto- 

 mium is transverse elliptical, with a conspicuous median longitudinal groove, -from which the 

 tentacle arises ; only its basal part is present. The lateral antennae, that emerge from the ante- 

 rior margin of the head, are also incomplete. Laterally on each side of the head there is a 

 pair of large eyes, the anterior being larger than the posterior one. Of the palps only the left 

 one is present ; it measures about twice the breadth of the head and is smooth, tapering dis- 

 tally, with an acute tip. The tentacular cirri have been lost on both sides ; only the basal 

 part of this parapodium is present. 



The specimen is devoid of scales, but probably there have been fifteen pairs of them, 

 as commonly on the segments 2, 4, 5, 7 — 23, 26, 29 and 32; the dorsal cirri are also wan- 

 ting. The cirrophores, laying nearly in the same line with the elytrophores, difter only by their 

 smaller diameter ; there are no dorsal tubercles. The ventral cirrus of the second parapodium 

 (first elytrophore segment), as usually much longer than of the succeeding ones, reaches to the 

 distal end of the bristle-fascicle ; in the other seofments the ventral cirrus emers^es from the 

 middle of the length of the neurojjodium and extends somewhat beyond its distal extremity. 

 The parapodia (PI. XVIII, fig. 3) have both setigerous lobes prolongated in a long digitiform 

 process, in which the distal end of the acicula lies enclosed. In Allm. sehióalensis, accordïng to 

 Mc Intosh, only the ventral division of the foot has such a long conical process ; but I sup- 

 pose, that the dorsal process has been overlooked by him, as was first also done by myself 

 in Allm. arafitrensis., because it lies hidden between the large dorsal bristles. These bristles 

 (PI. XVIII, fig. 5) lie in a fan-shaped fascicle and are as usually faintly curved, broad with 

 obtuse tips, longitudinal striae and numerous spinous rows in their distal half: there is an an- 



l) Named after the Arafma Sea, in which it was found.
