In tlio al)yencc' of specimens within reach of me I will make 

 the following extract from Mooee's description which was based 

 on a single incomplete specimen consisting of IGO segments, 

 al)()nt 100 of these constituting the posterior body region. 



Length of the specimen 98 mm. ; the breadth 4 mm. includ- 

 ing bristles in the anterior region, and 5.3 mm. at G3rd segment, 

 or the beginning of tbe posterior region. Prostomium bluntly 

 conical, 4-ringed, slightly depressed, length twice width. 



Parapodium of 15th segment consists of a rather stout ventral 

 ramus divided into a broad foliaceous anterior lobe with two 

 tongue -like tips and a somewhat slender lanceolate posterior 

 lobe; ventral cirrus stout. Dorsal cirrus consists of a rather stout 

 rounded stalk, with swollen base and somewhat flattened 

 foliaceous appendage. 



Typical parapodium of the posterior region (75th segment) 

 wifli two widely separated rami ; the ventral ramus essentially 

 as ill para podia of the anterior region, Imt with ])oth lobes much 

 l»i(';((i(i- and more leaf-like, with tlie 2 divisions of anterior lobe 

 iiioiHMlivCTgcnt, ])()11i divisions being longer and the dorsal division 

 largei- lliaii (1ie posterior lobe; ventral cirrus relatively short. 

 Dorsal ramus al)out jV as long as tlie ventral. Dorsal cirrus arising 

 iVoui liase of tbe dd'siil ramus and directed almost vertically dorsad. 

 ^'ellll•al lii'istles compoiiiid, with very long shaft and slender 

 liladc. Doisal bristles simpk', slightly bent, the surface marked 

 witli line granules, wliieli appear as somewhat irregular serration 

 at tlie (.'dire.
