segments and from 120 to 190 mm. in length, of a pale rose colour dorsally, pale iridescent 

 ventrally. Two small anal cirri. Spines generally black throughout. Spatulate bristles 

 with a long filament on one edge. Compound, with stout terminal piece, and bifid. Hook 

 commencing about the thirtieth segment, and it is also black. Great dental plates with five 

 or six teeth. Azygos plate, five to six teeth ; anterior plates, four to eight teeth on left, 

 eight to ten on right. Posterior process of apparatus one third length of maxilla?. V 

 and VI anteriorly have each a tooth. Branchiaa commence on the seventh foot and 

 continue almost to the tip of the tail. The divisions generally do not exceed four, but 

 sometimes six to eight occur, and there are for the most part three anteriorly. Inhabits 

 parchment-like tubes often on Lophohelia and Awphihelia.

Habitat— Large examples dredged in the 'Porcupine' Expedition of 1869 in 173 

 fathoms between Galway and the Porcupine Bank. Amongst colonies of Lophohelia 

 prolifera at a depth of 200 fathoms, 50 miles off Bolus Head, Kerry (F. Buchanan). 



Sand Key, Florida, in 100 fathoms (Pourtales). Gulf of Gasgoiue (Marion and 

 Roule). South of Cap St. Maira di Leuca (Marenzeller). Norway (Norman). 



Head (Plate LXV, fig. 7) with the palpi separated by a notch in front and with a 

 deep hollow dorsally anterior to each frontal tentacle. These are about the diameter of 

 the head in spirit, and retain their crenations. They are little tapered in several examples, 

 but in one in which the left had been reproduced it was as subulate as a dorsal cirrus. 

 Behind these are the longer median and two lateral tentacles, the cirrophore of the former 

 being just posterior to the line from the notch between the palpi, whilst the latter tentacles 

 are slightly in front at each side. All bear traces of crenations. Behind the frontal and 

 exterior to the lateral tentacle is the eye, which is of moderate size. 



Body 6 — 8 ins. long and about 4 mm. broad in front, very little tapered anteriorly, 

 but posteriorly diminishing to a slender tail with two cirri. Segments 100 — 150. First 

 segment about as broad as the three following, with a deep notch laterally opposite the 

 palpi, and a crenate border inferiorly. The second segment is shorter than the third and 

 bears the tentacular cirri, which vary in length, but often extend beyond the frontal 

 border of the first segment, and, Miss Buchanan observes, even beyond the palpi. 



The armature of the proboscis (Plate LXV, figs. 7 a and 7 b) corresponds with the 

 description of Marenzeller. The posterior appendages of the maxillas are lobate. The
