antennae and cirri are densely covered with long cilia. The head (PI. XX, fig. 7) is somewhat 

 more broad than long, divided by a median groove in two halves, each terminating anteriorly 

 in a conspicuous frontal peak. There are two pairs of large eyes ; the anterior one situated on 

 the lateral prominence of the head (not below the frontal peak as in Gatt. cirrosa Pall.), the 

 other pair placed on its posterior part. The tentacle arises with a short dark-tinged basal part from 

 the triangular notch of the head; its distal joint, twice and a half as long as the head, with 

 a smoüth filiform tip, is densely covered with long cilia, that are slightly clavated distally. The 

 lateral antennae, not quite half as long as the tentacle, also terminate with a bare filiform tip 

 and are densely covered with cilia. The palps, only somewhat longer than the lateral antennae, 

 have an enlarged base and are tapering distally ; they are covered with small papillae. The 

 tentacular cirri have nearly the same length and appearance as the tentacle. The nuchal collar 

 has a papilla in the centre. In the parapodia the neuropodial branch is provided with a rather 

 long cylindrical lobe ; its bristles (PI. XX, fig. 8), not much longer than the notopodial ones, 

 have a short dilated subterminal part and a short acute secondary process below the tip. A 

 large notopodial fascicle cóntains bristles of the usual shape, with a smooth, acute tip and 

 laciniated fringes over their total length. The dorsal cirri are nearly as long as the neuropodial 

 fascicle, densely covered with cilia ; the ventral cirri are short and do not reach the distal 

 extremity of the feet.

Macassar, PiLLER. 



In the collections of the Leiden Museum I found a Hannothoid-^^orm, collected by 

 Mr. PiLLER in the neighbourhood of Macassar. Unfortunately it is in an indifferent state of pre- 

 servation and therefore it is difficult to say, wether it belongs to a known species. Only a single 

 elytron (PI. XX, fig. 5) is left, that much resembles those of Harmoth. imbricata ; it is ellipsoidal, 

 with the scar of attachment situated somewhat eccentrically, nearest to the posterior border. The 

 whole surface of the scale is beset with small tubercles, that in its anterior region are very 

 low, but posteriorly become gradually longer and attain a blunt, conical shape ; its margin is 

 smooth, only at the posterior border there occur six large, clavate papillae. In the parapodia 

 the neuropodium is nearly cylindrical and much surpasses the short notopodium in length ; 

 both are provided with a digitiform process, surrounding the distal end of the acicula. The 

 neuropodial bristles are indistinctly bifurcated at the apex and are provided with several laci- 

 niated rows along the subterminal, dilated part; the notopodial setae have the usual shape. 

 The ventral cirrus is half as long as the neuropodial lobe ; the dorsal cirrus with its filiform 

 tip reaches the extremity of the neuropodial fascicle. The head is provided with two acute 

 frontal peaks; eyes could not be recognised. The tentacle is at least twice as long as the 

 lateral antennae. Harmothoc imbricata is already mentioned from the coast of Japan by von 

 Marenzeller ^) and Izuka-).
