OPHELIIDAE. 



11. Travisia kerguelensis. 



(PI. XLIL, figs. 1-2.) 

 Travisia kerguelensis, Mcintosh, 1885, ^f. cit., p. 357 ; Ehlers, 1897, up. cit., p. 97. 



In this worm the mouth lies between the first and second 

 setigerous segments, and in front of the first setiger there is an 

 achaetous segment presumably homologous with the peristome of 

 other forms, but here in front of the buccal orifice. In the figures 

 given by Mcintosh and Ehlers the lateral organs (Seitenorgane), 

 which superficially resemble those of the Capitellidae,^ are not shown. 

 They lie between the notopodial and neuropodial fascicles and appear 

 as pits in the pleural wall, commencing in the first postoral segment 

 and ending in the twenty-first postoral (PL XLII., fig. 2). 



The segmental nephridiopores are seen below the ventral fascicles, 

 commencing at the fifth postoral and ending at the thirteenth postoral 

 segment. The posterior segments give rise to rounded papillae which 

 eventually form a fringe round the pygidium. 



Two specimens were obtained from Cape Adare in 7 to 10 fathoms ; 

 length 20 mm., maximum width nearly 8 mm. 



MALDANIDAE. 



Ehodine. 



Malragren, 1865, op. cit., p. 189, Char, emend. 



Uncini in segmentis uncinigeris anterioribus biseriales, in ceteris uniseriales, sine 

 fascicule setularum sub rostro, in segmentis IV anticis setigeris nulli, in ceteris 

 numerosi. 



In his description of Bhodine sima, Ehlers ^ seems to have been 

 the first to indicate that the uncini are biserial in a limited number 

 of segments only, uniserial in the rest. 



12. Ehodine loveni. 



(Ph XLVL, tigs. 3-5.) 



Rhodine loveni, Malmgren, A. J., 1867, ' Annulata Polychaeta,' Taf. X., fig. 61. 



Several specimens of this interesting species were obtained off Cape 

 Adare in 8 fathoms, 17th January, 1900 ; sea temperature 30° Eahr. 



' Cf. Eisig, ' Monograpli cler Capitelliden.' They closely resemble the corresponding 

 organs in a Dasybranchus which 1 have examined.
