by the body about 5 mm.; then the bod) tapers gradually towards the tip of the hindpart. The first 

 parapodium is elytron-carrying and, as far as it was possible to state, the arrangement of the elytra 

 is the usual. 



The cephalic lobe (PI. IV, figs. 2,5), the shape of which is broad with embossing sides, is of the 

 L,epidonote type; frontal prominences are lacking and the side-halves of the head are continued directly in 

 the paired tentacles. Eyes are lacking. All appendages are exceedingly short and, rela- 

 tivel) to their length, rather thick. The impaired tentacle reaches c. 1 nun. in length, 

 the paired tentacles are inconspicuously shorter. The tentacles taper towards the apex 

 and are provided with a short terminal filament. The palps are quite peculiar; they 

 are represented by a whartshaped prominence on each side, in length about the half 

 of that of the tentacles; their tip is bluntly rounded and there is no trace of terminal 

 filament. All in all they are quite different from what we are accustomed to see 

 in the Polynoids 



Unfortunately the pharynx is not protruded to such a degree that it is possible 

 to state the presence of jaws, and as only one specimen is at my disposal I have 

 considered it not to be convenient to undertake any dissection. 



In the middle-line of the dorsum is found a row of warty prominences, one . „ 



on each segment, and at the base of each foot is found a similar prominence on 

 the dorsal side, so that the dorsum shows three longitudinal rows of warty prominences. (PI. IV, fig. 2). 

 The parapodium is conspicuously reduced, mainly the dorsal branch, which carries no seta.-; 

 only a relatively weak acicle is found in its interior (fig. 18). The ventral setae are short and clumsy, with 

 a short broad end-blade terminating in a strong curved tip and entirely devoid of spines and hairs. Resides 

 the acicle only three or four such bristles are found in the neural part of the parapodium (fig. [9). 



The dorsal cirri are short and clavate (PL 2, fig. 8); originating 

 on the dorsal side of the parapodium they are bent in a right 

 angle down towards the former. Ventral cirri are lacking on all 

 feet except the foremost — also a peculiar feature. 



The scales are almost circular or quadrangular, with strongly 

 rounded angles. The first is mainly the case with the smaller 

 scales found in the hindmost part of the body. It must also be 

 pointed out, as a strange feature not common in Polynoids, that 

 the scales grow successively smaller towards the hindpart of the 

 animal. Along the edge of the scales and spread over their sur- 

 face are found peculiar short digitate prominences different in 

 number, corresponding to the size of the scale; in one of the 

 largest, figured PI. Ill, fig. 12, are found twelve such prominences along the edge of the elytron and 

 five on its surface. In the smaller scales from the hindpart of the body are found no prominences 

 along the edge and only two or three on the surface. 



Dorsal cirri and elytra are densely beset with short and clumsy papillae, giving the organs con- 

 cerned a velvety aspect.
