The setae of the notopodial fascicle (PL XVHI, tïg. 8) are sword-shaped, finely serrated, with 

 an undivided tip; its acicula also hes enclosed in a filiform prolongation. The dorsal cirrus is 

 very long, extending beyond the extremity of the neuropodial fascicle, and is dilated beneath 

 its filiform tip ; the ventral cirrus does not reach beyond the neuropodial lobe.

At the above-named Station (presuinably pelagically) a small Polynoid-worm in a stade 

 of sexual maturity was found, that on account of the structure of its parapodial lobes is to be 

 raneed amone the eenus Allmaniella. It has a length of about 12 mm. and the number of its 

 segments amounts to 33. Unfortunately all the scales (15 pairs in number) have been lost. The 

 head is dotted with brown spots and also each segment has on its dorsum a transverse brown 

 band, divided into two by a narrow white line. The head, that is much broader than long, bears 

 on the middle of its frontal margin the basal joints of the lateral antennae ; their distal part 

 is twice as long as the head and terminates in a filiform tip. From the middle of its dorsum 

 the tentacle arises, which is nearly as long as the lateral antennae. Two large eyes are situated 

 on the lateral sides of the head. The parapodia (PI. XYIII, fig. 10) have the anterior lip of 

 the ventral lobe produced in a long conical process, inclosing the acicula. All the bristles have a 

 vitreous appearance, only the aciculae are pale yellow. The neuropodial setae (PI. XIII, fig. 11) 

 have the subterminal dilated part provided with faintly denticulated rows and a bifid tip. The 

 notopodium is feebly developed and provided with a short cylindrical lobe, surrounding the 

 tip of the acicula; its bristles (PI. XVIII, fig. 12) are nearly straight, faintly denticulated. The 

 dor.sal cirrus is long, extending beyond the distal extremity of the neuropodial fascicle; the 

 ventral one however does not reach beyond the tip of the ioot.
