Typosyllis variegata, Grube. 



At Positions 38 vtwo), 43 (one), 53 (one), 58 (one\ 



Depth, 44-49 fath. 



The specimens appear only to differ from the account of Langerhans 

 in the smaller number of articulations in the dorsal cirri of the body. 

 Langerhans gives these as 34 and 24 in alternate segments. In these 

 specimens they number about 24 and 16 respectively. Grube (83) 

 first described the chaetae as with simply hooked end-pieces. Sub- 

 sequent authors have described them as bifid. In all the specimens 

 here considered they are very faintly bifid in some of the an- 

 terior segments, but distinctly so in the median and posterior seg- 

 ments. The transversely-placed S-shaped dark marking, as described 

 by Langerhans, in the dorsal surface of the segments, is distinct in the 

 anterior segments of some specimens but absent in others (as preserved 

 in spirit). 



HESIOXIDAE. 

 Castalia punctata {0. F. Miiller), 



One specimen at Position 33. Length in spirit, 10 mm. 



Depth, 42 fath. 



APHEODITIDAE. 

 Aphrodita aculeata, Linnaeus. 



At Positions 6 (one), 11 (one), 31 (a few). 



Depth. 40-42 fath. 



Hermione hystrix ^Savigny). 



At Positions S, 11, 16, 17 (one each), 18 (two), 19 (one), 20, 22, 25 

 (two), 31, 35 (one), 37 (one), 38, 43 (one), 44 (two), 58 (one), 59 

 (three), 62. 

 Depth, 43-50 fath. 



The greater frequency of this species in comparison with the pre- 

 ceding is probably due to the generally rough character of the ground 

 being more favourable to it (cp. Allen, 1). 



Lepidonotus squamatus (Linnaeus). 

 At Positions 13 ^one), 34 (one), 70 (two). 

 Depth, 40-42 fath. 



Lagisca floccosa (Savigny). 



At Positions 10, 12, 13, 14, 32, 33, 34, 35 (one each) ; 45 (three 



young), 49, 51 (two each). 58 (three), 59 (four), 60, 62 (two each), 



70 (four), 72 (one), vii (two), 80 (seven). 

 Depth, 42-51 fath. or over.
