UMBELLULA CARPENTERI Kolliker. 
Umbellula carpenteri IOLLIKER, Report on the Pennatulida dredged by 
H. M. S. Challenger during the years 1873-1876, 1880, p. 23. 
A number of specimens collected during the Hawaiian cruise at 
the following stations are referable to this species: 
Distribution—Northeast coast of Hawaii: Station 4060, 759-913 
fathoms. (Cat. No. 25343, U.S.N.M.) : 
Between Oahu and Kaui: Station 4125, 963-1124 fathoms. (Cat. 
No. 25344, U.S.N.M.) 
Off ane Station 4139, 512-339 fathoms (Cat. No. 25342, 
U.S.N.M.); Station 4187, 508-703 fathoms (Cat. No. 25345, 
U.S.N.M.). 
The type specimen was secured by the OheMengor in the North Pa- 
cific, south of Yeddo, from a depth of 565 fathoms. 
UMBELLULA JORDANI, new species. 
Plate XLII, fig. 3. 
Total length of large specimen about 400 mm.; polyps to tentacle 
bases 17 mm.; tentacles, not fully expanded, 11 mm. There is an 
end bulb at proximal end of the stem which is continuous with a 
swelling which is distinctly quadrangular in section. Otherwise the 
stem is quite slender, quadrangular in section, gradually merging at 
its distal end into the short rachis. 
Polyps nine, in largest specimen, eight being arranged around a 
central ninth, the whole head showing little trace of bilateral sym- 
metry in this specimen, although it is distinct in other and smaller 
ones. Polyp bodies smooth, not strongly corrugated as in U. hualey?, 
which appears to be the most nearly related known species. 
Zooids.—Rather large, not very much crowded on terminal swell- 
ing, where they tend to assume a linear arrangement, the lines being 
continuous with the patches of zooids between the polyp bases. These 
patches are drawn into a long angle below. A few zooids are seen 
among the polyps on the dorsal side, and also on the lower swelling 
and end bulb. They are not so large as those of U. huwxleyz. 
Spicules apparently wanting. 
Color.—In alcohol, stem nearly white; polyps umber brown, ex- 
cept where the Oeics is abraded. In ‘uh latter case the color is 
bluish white. 
This species resembles U. hualeyi in color, and U. magniflora in 
arrangement of zooids, but does not have the conspicuous terminal 
flattened swelling of the latter. 
Named in honor of President David Starr Jordan, of Stanford 
University. 
Type.—Cat. No. 25319, U.S.N.M., Albatross Station 3985, oft 
Kauai, 430-777 fathoms.
