Localihj. — Station 4975; Shio Misaki Light, N. 49° E., 7 miles; 

 712 to 545 fathoms. 



General distribution. — The type-locality is in the South Sea, east 

 of Kerguelen Island, 1,600 fathoms. Hawaiian region, 216-438 fath- 

 oms (Nutting), 



UMBELLULA CARPENTERI Kolliker. 

 Umbellula carpenteri Kolliker, Challenger Reports, the Pennatulida, 1880, p. 23. 



Two specimens, both female with ova, were secured at station 

 5080; 505 fathoms. 



The larger specimen is 75 cm. in length, the head measuring 5 cm., 

 polyp bodies 2.4 cm. long, and the tentacles 1.6 cm. The swelling 

 above the end bulb is 6 mm. wide, and about 4.3 cm. long. The 

 stem is very slender, its least diameter being 1.2 mm. 



There are 8 polyps, almost white, with 8 longitudinal corruga- 

 tions. The tentacles are smooth, their dorsal surfaces colorless, 

 the rest of the tentacles and pinnules being very light salmon. The 

 pinnules are about 30 in number. 



The zooids are numerous and many of them bear single tentacles, 

 usually unbranched. There are very few calcareous particles, 

 even in the end bulb. 



The smaller specimen also has 8 polyps and agrees more nearly 

 with Kolliker's measurements. The details are much the same as 

 in the other specimen. 



Localities. —Station 5080; Omai Saki Light, N. 23.5° E., 28 miles; 

 505 fathoms. Specimens collected at station 5015, lat. 46° 44' N.; 

 long. 144° 02' E., 510 fathoms, are apparently of tliis species. 



General distribution. — Type-locality, South Polar Sea, southwest 

 of Australia, 1,975 and 1,950 fathoms. Hawaiian region, 595 to 

 1,124 fathoms (Nutting). 



UMBELLULA ELOISA, new species. 



Plate 6, figs. 3, 3a. 



Total length of colony, 73 cm. Head, including enlargement of 

 stem, 7 cm. The lower part of the stem has no very evident end 

 bulb, but terminates in a bent, club-shaped end, which is continuous 

 wdth the stem swelling. The greatest diameter of the swelling is 



6 mm; the least diameter of the stem, 2 mm. The beginning 

 of the enlargement of the rachis to the base of the polyps is 1.9 cm., 

 the diameter of the rachis just below the polyp bases being 1.5 cm. 

 The polyps are very large, 14 in number, 7 in an outer whorl and 



7 within. The length of the largest polyp to tentacle bases is 2.4 

 cm. The tentacles are much shrunken and are 1.7 cm. in length, 

 making the whole length of tentacles and polyp 4.1 cm. This is 

 the largest alcyonoid polyp that the writer has seen.
