Lumljriconereis sphaerocephala, Ehlers. Abhancll. Gesell. 

 Wiss. Gottingen. Neuseel. Annal.. 1904, p. 33. 



A single imperfect specimen of small size and. dark coppery 

 brown in colour, with a high iridescence, appears to belong 

 to this species. The prostomium is, however, rather longer 

 than broad, and, therefore, less nearly spherical than in 

 Ehler's description ; this may be a matter of preservation. 

 I have preparations of this species, which is common on 

 New Zealand coasts, and it agrees well with them. 



Loc. East of Babel Island, Bass Strait, about 70 fathoms. 

 Distribution. New Zealand ; Chatham Islands. 



LUMBRICONEREIS GULiELMi, 1 sp. nov. 

 (Plate xlii., figs. 81-88; Plate xliii., figs. 89-1)4.) 



Two imperfect individuals of laige size, one consisting of 

 the head and 58 chaetigerous segments, measures 70 mm. in 

 length, with a diameter of 7 mm. It is narrower anteriorly 

 where it is only 3 mm. across the peristomium The other 

 specimen consists of 133 :-egments and the head, and has a 

 length of !)9 mm. There is little evidence of a posterior 

 taperivg, for at its truncated end it still measures 6mm. in 

 width. 



The worm is nearly cylindrical, its height being 6-7 mm. 

 The segments are short as usual, being about l-6th to l-7th 

 of the diameter of the body. 



The colour is coppery brown, with a bright green iridescence 

 and the chaetse are glistening brown. 



The prostomium (PI. xlii., figs. 81, 82) is a rounded cone 

 as broad as its length, with no conspicuous eyes, but in 

 their place a curved transverse row of 6-8 small black spots 

 close together on each side of the base, and extending 

 laterally so as to be visible from the side. In the second 

 individual, which is in a better state of preservation, these 

 pigment spots are less distinct ; they form a row right across 

 the base of the prostomium, and are not confined to the sides. 



1. 1 have taken the liberty of naming this line speck's alter the veteran 

 zoologist. Professor William C. M'lntosh.
