A fragmentary specimen taken off the north coast of Maui, at Sta- 

 tion 4098, 95-152 fathoms (Cat. No. 22593, U.S.N.M.), is referred to 

 this species. 



The type was secured by the Cliallenger off Tristan da Cunha 

 Island, from a depth of 360 fathoms. 



Genus MENELLA Gray. 



Colony unbranched ; calyces on all sides of stem, closely set ; polyps 

 retractile, in retraction leaving an oblong concavity at the summit 

 of the calyx. 



MENELLA GRANDIFLORA, new species. 



Plate XLIV, fig. 5 ; plate XLVIII, fig. 6. 



Colony an unbranched stem arising from a disk-like leathery base, 

 attaining a height of 256 mm. and a diameter of 3^ mm. The stem 

 is slightly expanded at the distal end, making it somewhat club- 

 shaped. 



Polyps very large, rather thickly emplanted on the sides, and more 

 closely on the front and back of stem. Calyces in form of truncated 

 cones 3^ mm. high and h\ mm. broad at base, elliptical in section. 

 The" polyp is often considerably exsertecl above the calyx, so that the 

 height of polyp and calyx together may be 7 mm. 



Spicules large warty, sometimes forked, disposed irregularly 

 around the base of the cone, with a tendency toward a circular ar- 

 rangement. They form eight vertical bands on the calyx walls; 

 those of each band being en chevron basally and more nearly vertical 

 distally, their ends projecting above the margins of the walls. 



The oesophageal region of the polyp is much more extensive than 

 usual in this family, and is surrounded by a number of rugosities 

 consisting of transversely disposed spicules, the upper rugosity form- 

 ing the collaret. Above this arise the tentacular spicules, disposed 

 en chevron basally and in several longitudinal rows distally. The 

 tentacles are erect and not distinctly folded over the mouth. 



Color of axis ver}^ dark brown, in places, with greenish golden 

 iridescence ; polyps very light brownish yellow, in alcohol. 



Type.—Q.^t. No. 22*590, U.S.N.M., Albatross Station 3992, off 

 Kauai, 528 fathoms.
