Family CHRYSOGORGIDZE Verrill. 
Ceenenchyma thin, polyps large, usually distant, in a single row 
and nonretractile; base of attachment calcareous. Calyces not evi- 
dent as separate from the polyp walls, to the shape of which they 
strictly conform; no operculum nor collaret. Axis, when denuded, 
generally with a brillant metallic lustre. 
Subfamily LMPIDOGORGIN A‘.4 
Colony simple, unbranched, slender ; polyps in a single row. 
Genus LEPIDOGORGIA Verrill. 
The characters of the genus are the same as those of the subfamily. 
LEPIDOGORGIA GIBBOSA, new species. 
Plate XLV, fig. 6; plate XLIX, fig. 5. 
The unbranched stems arise singly or in tufts from a fibrous mass 
of rootlets which is small in comparison to the size of the stems; 
height 150-200 mm. 
Stem flexible, slender, covered with a thin coenenchyma; bearing 
equidistant and unilateral polyps inclined toward the distal end. 
Polyps 27 mm. apart, emplanted along the whole length of the 
stem; rather short, arising from a distinct swelling, which is larger 
than the polyp body itself and embraces the stem. The polyp body 
is sharply distinguished from this swelling, very short, being but 
about 1 mm. in height to tentacles; tentacles very long and thread- 
hke, nonretractile, with long filamentous fringes. The tentacles are 
very difficult to measure, on account of their being loosely coiled, but 
they are at least twice as long as the polyp body. | 
The spicules are small, rod-like, sometimes cruciform, rather 
sparsely distributed, longitudinally placed on polyp body, thickly dis- 
tributed on the basal swelling and the cortex, apparently absent in the 
tentacles. Those of the cortex are scale-like and lobed in various 
ways. All spicules are without pronounced verruce. 
Siphonozooids are present in this species, between the basal 
swellings. 
Color.—Light buffy yellow, the bared stems showing a dull golden 
iridescence. ) 
Type.—Cat. No. 25330, U.S.N.M., Albatross Station 3990, off 
Kauai, 296-326 fathoms. 
Additional locality.—Off Kauai: Station 3989, 165-469 fathoms 
(Cat. No. 25372, U.S.N.M.). Numerous specimens. 
“The arrangement of subfamilies, genera, and subgenera here adopted is 
substantially that of Versluys in his excellent monograph of the Chrysogorgidz 
of the Siboga expedition.
