the anterior part of the caruncle, that is enlarged. The latter organ bears 6 or 7 lateral lamellae 

 on each side of its axis. Considering the facts mentioned in the present paper, it is somewhat 

 doubtful to me if the specimens from Pulu Weh, described in my paper above referred to, do 

 not belong to an other species of the genus Pherecardia, for they want the buff ground-colour, 

 whereas their cephalic lobe is not hidden under the anterior part of the caruncle-, their caruncle 

 is larger and has more lateral lamellae and also their branchiae appear to be more developed. 

 However this question can only be decided, when more well-preserved specimens will be at 

 our disposal. 



Genus nov. Pherecardites. 



Body elongate. Caruncle consisting of a median axis and some lateral lamellae, directed 

 backward. Eyes dubious. Branchiae ramified, commencing on the first segment. Ventral bristles 

 partly bifurcated; dorsal ones harpoon-shaped, with serrations having the shape of an Y. This 

 o-enus is intermediate between Heniwdicc and Pherecardia, its ventral bristles resemblino- those

of Hcrmodice, the dorsal ones those of Pherecardia.

This is a small worm, the largest specimen of which does not measure more than 7 mm. 

 in length and 2 1 /,, mm. in breadth;.its body, much resembling that of a Polynoid, consists of 

 about 30 segments, that are nearly of the same breadth over its entire length, only posteriorly 

 they become somewhat narrower. The prostomium has a frontal part, that is trapezoidal of 

 shape and provided with black spots; its caruncle extends over three segments and consists of 

 a median axis and four lateral lobes, directed backward. In front of it a long unpaired antenna 

 arises, that has a stout base and reaches with its tapering distal extremity nearly to the end 

 of the caruncle; the paired antennae are rather short. Whether there are real eyes could not 

 be settled decidedly ; there is some aggregation of pigment, but it is not conspicuously limited. 

 The branchiae commence on the first segment ; they consist of a small tuft of branched filaments. 

 The neuropodial fascicle contains a number of short, bifurcated bristles (PI. IX, fig. 17), the 

 long limb of which has a somewhat convex dorsal side, whereas its internal border is coarsely 

 denticulated; their short limb is not much more as a spur and their shaft has a granular axis. 

 These bristles show great resemblance to the ventral setae of Hermodice carunculata (Chall. Annel. 

 PI. UIA, figs. 3 and 4). Some of these bristles (PI. IX, fig. iS) are longer and even have lost 

 their spur; they much resemble the corresponding setae of Pherecardia lobata (Eucarunculata 

 %rubei var. gracilis Potts: loc. cit. pi. 46, fig. 11). Besides these bifurcated setae there occur 

 some simple capillary bristles, with a serrulated distal extremity. The notopodial fascicle is 

 provided with a great number of harpoon-shaped bristles (PI. IX, fig. 19), with a row of Y-like 

 denticles along one border, about of the same feature as the dorsal setae of Pherecardia lobata ;
