cirriphore, lying laterally from the series of elytrophores, is connected by a ridge with a dor- 

 sal tubercle. 



II. H a rmoth oïnae. 

 Genus Harmothoë Kinberg '). 



Body short, consisting of 35 — 37 segments. Scales 15 pairs, covering the whole dorsum, 

 inserted upon segments 2, 4, 5, 7... 23, 26, 29 and 32. Antennae and cirri sometimes den- 

 sely covered with cilia. Neuropodial bristles stouter than notopodial ones, with spinous distal 

 region and simple or bifid tip.

 I specimen. 



At this Station a worm was caught, broken in two fragments and consisting of 37 seg- 

 ments. The head (PI. XX, fig. 2) is blackish, nearly as long as broad, divided in two halves 

 by a conspicuous median groove ; anteriorly it shows two blunt frontal peaks, that bear the 

 large anterior eyes. The eyes of the posterior pair are smaller and lie hidden under a nuchal 

 collar. The tentacle, nearly as long as the palpi, terminates in a filiform tip ; the lateral an- 

 tennae, measuring two thirds of the length of the tentacle, are provided with papillae and 

 a filiform tip. The scales (PI. XX, fig. i) are blackish, roundish, slightly concave in front, with 

 the scar of attachment situated eccentrically ; their surface is covered with small tubercles, pas- 

 sing outward in conical spines, whereas slight oval papillae occur along the external border. 

 On the dorsum of each segment there occurs a broad transverse band (sometimes divided in 

 two) succeeded by a smaller one. The ventral branch of the parapodia terminates in a digiti- 

 form lobe, enclosing the tip of the acicula ; its bristles are slender, with a smooth bifid tip 

 and a subterminal dilated part with laciniate rows. The notopodium also terminates in a pointed 

 process, enclosing the acicula ; its bristles, of the usual appearance, are very slightly bent and are 

 provided with a bare acute tip. The ventral cirrus, dilated in its distal part and tapering 

 distally, is provided with papillae and does not extend to the distal extremity of the foot. The 

 dorsal cirrus, also densely beset with papillae and dilated beneath the filiform tip, is not quite 

 as long as the neuropodial fascicle.
