Distribution.— OS. the coast of Kauai : Station 3998, 228-235 fath- 

 oms (Cat. No. 25391, U.S.N.M.). 



Northeast coast of Hawaii: Station 4058, 190-195 fathoms (Cat. 

 No. 22587, U.S.N.M.). 



The largest specimen, taken as a type for the above description, 

 was without a locality label. 



CERATOISIS PAUCISPINOSA Wright and Studer. 



Ceratoisis jmncispinosa Weight and Studer, Report on the 'Alcyonaria col- 

 lected by H. M. S. Cliallengor dnring the years 1873-1876, 1889, p. 28. 



A fragmentary specimen with but four joints and the polj'^ps much 

 decomjjosed agrees fairly well with the original description of this 

 species. 



Distnhution. — North coast of Molokai : Station 3901, 295 fathoms 

 (Cat. No. 22584, U.S.N.M.). 



The t^^pe specimen was taken by the Challenger off the coast of 

 Japan, 345 fathoms, 



CERATOISIS GRANDIS, new species. 



Plate XLIII, fig. 2; plate XLIX, fig. 3. 



Two fragments of the denuded axis measure, together, 437 mm., 

 the indications being that the entire specimen was much longer. 

 Calcareous internodes excessively^ elongated, none being certainly 

 complete; measurements, 110 mm., 118 mm., 105 mm., and 70 mm. 

 (the latter evidently broken). These internodes vary from 8 mm. 

 to 2|^ mm. in diameter. There are but two horny internodes present, 

 measuring 4 mm. and 2| mm. in length, the longer one being be- 

 tween the stouter calcareous internodes, and these latter are also the 

 longest. All of the calcareous internodes have a distinct central 

 canal. 



The polyps were all detached from the axis, but were wrapped 

 in a cloth with it. Thej^ are typical of the genus Bathygorgia of 

 Wright and Studer, which is here included with Ceratoisis. Poh^'ps 

 large, slender-bodied, arising from a basal expansion and ending 

 in an expanded distal part bearing the tentacles ; length, 4^ to 8 mm. ; 

 diameter below distal expansion 1 mm., across distal part 2^ mm. ; 

 tentacles not fully retracted, but coiled over the mouth. 



Spicules long, slender, sometimes slightly forked, rarely cruciform, 

 often bar-like, sometimes approaching the needle-like form; appar- 

 ently absent from the skin-like coenenchyma peeled from the axis; 

 but slender spicules are present in the basal expansions of the polyps. 

 Very large spicules surround the polyps, arranged vertically in the 

 calyx walls, although they are often inclined to be more or less diag- 

 onal ; strong spicules projecting up from the tentacle bases, and large
