508 DR. W. C. M'INTOSH ON THE ANNELIDA 



structed of transparent quartzose sand-particles set in the opaque secretion, so that, at 

 first sight, they seem pitted all over. 



Cistenides hyperboeea, Malmgren. Station 1, 175 fathoms, off Hare Island, Disco. 

 The tubes of this species generally present a darker hue and less regular masonry. The 

 cement in both is more abundant than in Pectinaria belgica or Amphictene auricoma, so 

 that the architecture in the latter is more finished. 



Am age auricula, Malmgren. Station 4. A small fragment seemed to approach 

 Samytha sexcirrata, Sars, but its condition negatived satisfactory results. 



Amphiteite cirrata, O. P. Mtiller. 5-20 fathoms, Godhavn Harbour, Disco. 



Nicolea arctica, Malmgren. 5-20 fathoms, Godhavn Harbour. The specimens are 

 larger than the following, and the pedicles of their branchiae are longer. 



Nicolea zostericola, (Erst. & Gr. Holsteinborg Harbour, 30 fathoms. 



Lejsna abranchiata, Malmgren. Stations 5 & 6. A fragment also from the latter 

 presents certain affinities with Lanassa Nordenskioldi, Malmgren ; but its condition is 

 such that a degree of doubt remains. The body is grooved along the ventral aspect 

 behind the ventral scutes. The bristles resemble those shown by Malmgren in Laphania 

 Boecki, that is, they have wings at the tip, and the latter in some is short and broad. 

 The hooks, again, have elevated crowns, with about 5 teeth above the large process, as 

 in Lanassa. 



Theleptjs circinnatus, Pabr. A small example from Station 5 ; fragment from Hol- 

 steinborg Harbour, 10 fathoms; large specimens from Station 1 (30 fathoms), 65° 00' N., 

 53° 00' W., H.M.S. ' Alert.' It is well to remember that the posterior hooks show two 

 teeth above the large fang. 



Trichobranchtjs glacialis, Mgrn. Station 12, 1450 fathoms, on a bottom of Glo- 

 bigerina-ooze and stones. The tubes are chiefly composed of Olobigerince. 



Tebebellides Stboemi, Sars. Station 6, 410 fathoms ; Station 7, 1100 fathoms ; 

 Godhavn Harbour, 5-20 fathoms ; and outside the latter in 80 fathoms. 



Sabella crassicornis, Sars. Fragments from Godhavn Harbour appear to belong 

 to this species. The occurrence of the branchiae in the tube showed that they did not 

 pertain to S.pavonia, as first supposed. The present species and S. spetsbergensis, Mgrm, 

 seem to be closely allied, but the condition of the specimen was such that absolute accu- 

 racy was not attainable. The pigment on the branchiae resembles that found in the 

 latter form. The tube is thin and tough. 



Etjchone analis, Kroyer. Station 4, 20 fathoms on shell-sand ; Holsteinborg Harbour, 

 10 fathoms. One was in a fine hyaline tube coated with coarse quartzose sand and 

 minute fragments of shells. 



Chone inpundibtjlipormis, Kroyer. Station 4 ; 5-20 fathoms in Godhavn Harbour. 

 The hooks (PI. LXV. fig. 17) differ from Dr. Malmgren' s figure. One was in a tough 

 brownish tube. 



Another Chone, evidently belonging to a different species, was dredged in the latter 

 locality, but it had apparently been dried before being placed in spirit. The collar is 

 large and of a similar form to that in C. infundibuliformis. The branchiae (which are
