90 DISCOVERY REPORTS 



Specific characters. There is a row of median dorsal pads running the whole 

 length of the body. The elytra are papillated and have clavate tubercles with crenate 

 tops. The dorsal bristles mostly have bearded tips and the ventral are unidentate with 

 two short rows of teeth on the shaft. 



Remarks. The specimens from St. 363 are distinctive in having in the hinder part 

 of the elytra a patch of relatively gigantic spinous pustules which are variable in shape 

 and size. 



Genus Eunoe, Malmgren 



As Harmothoe, but with unidentate ventral bristles.

Occurrence. St. 123 (3); WS 33 (2); MS 62 (i). 



Specific characters. A small species measuring about 10 mm. by i mm. without 

 the feet for 34 chaetigers. There is a typical harmothoid head and two pairs of rather 

 large eyes. The anterior pair are on the sides of the head in the middle, and the posterior 

 are dorsal but at the extreme lateral edges. The elytra have both marginal and sub- 

 marginal papillae and both large and small tubercles with irregular jagged tips. The 

 dorsal bristles are numerous and pectinated : the upper neuropodial bristles are rather 

 elongate and slender with a long spinous region showing scales on the blade as well as 

 a toothed edge. From above dov^nwards the bristles show an increasingly shorter 

 spinous region, and the lower ventral bristles are expanded distally and have a very 

 short spinous region showing a toothed edge only. All the neuropodial bristles are 

 unidentate. This appears to be the normal condition, but in the specimens from St. 123 

 the two or three uppermost bristles in the ventral bundle show distinct traces of a 

 second tooth. 



Genus Eulagisca, Mcintosh 



The arrangement of the elytra is as in Harmothoe . The insertion of the lateral tentacles 

 is terminal or subterminal, not ventral. A large facial tubercle is present. The dorsal 

 bristles are stouter than the ventral and lightly pectinated : the ventral are frilled and 

 unidentate.

Occurrence. St. WS 246 (i). 



Specific characters. This is a large species measuring up to about 80 mm. by 

 15 mm. without the feet for 36 segments. It is superficially very like a Panthalid. The 

 head is of the lepidonotid type in that the insertion of the lateral tentacles is terminal, 

 but the top of the median ceratophore Hes a little above the lateral ceratophores after
