348 L. R. CRAWSHAY. 



HEEMELLIDAE. 

 Sabellaria spinulosa, Leuckart. 



Kecorded in small numbers at Positions 4-7, 13, 31-33, 35, 44, 45, 



47, 49, 51, 53, 56, 59, 60, 72, vii, 80. 

 Most commonly on shells of Pecten, also on tubes of PaUasia and 

 on stones. 



Depth, 40-51 fath. or over. 



PaUasia murata, Allen. 



Tubes or portions of tubes of this species were obtained at Positions 

 5, 6, 7, 10, 11, 12, 14, 17, 19, 31, 32, 37, 46, 53, 56, 63, 72. 



Depth, 40-50 fath. 



Living specimens or fragments of such were obtained at Positions 17, 

 63, and 72. A large colony was passed through at Position 17, where 

 portions of about six specimens of the living animal were brought up 

 in the dredge. This was by far the largest settlement touched in the 

 course of the work (cp. Crawshay, 4, p. 103), though the absence of 

 living specimens in the great majority of the hauls is largely to be 

 explained by the difficulty of working the dredge deep enough to 

 secure them. 



HIRUDINEA. 

 Pontobdella muricata, Linnaeus. 



One specimen at each of the Positions 44 and 52. 



Depth, 43-46 fath. 



At Position 44, in addition to the specimen, four lots of ova were 

 obtained in dead valves of Pecten oyercularis. 



SIPUNCULOIDEA. 



Phascolosoma vulgare (de Blainville). 



One specimen at each of the Positions 15 and 38. Length 30 and 



20 mm. respectively. 

 Depth, 44 fath. 

 Mr. G. Southern kindly identified this species. 



ARTHROPODA. 



CRUSTACEA. 

 CIERIPEDIA. 

 BALANIDAE. 

 Balanus crenatus, Bruguiere. 



Eecorded only at Position 4, but probably present in other hauls. 



Pyrgoma anglicum, Leach. 



On Caryophyllia smithi, at Positions 7, 11, 44, 45, 59. 

 Depth, 42-49 fath.
