STACHYODES REGULARIS Wright and Studer. 



A specimen of this species was dredged at Station 3879, south of 

 Lanai Island, 923-1,081 fathoms. The original specimens were se- 

 cured by the Challenger in the South Atlantic, near Tristan da Cunha, 

 75-150 fathoms. 



STACHYODES DICHOTOMA Versluys. 



Stachijodes dichotoma Versluys, Die Gorgoniden der Siboga-Expedition, 

 II, Die Primnoidse, 1906, p. 88. 



Several specimens referred to this species were secured by the 

 Bureau of Fisheries steamer Albatross. Each specimen had coiled 

 around its branches a simple-armed basket fish, probably belonging 

 to the genus Ophiocreas. One specimen was 14 inches high. 



Distribution.— 0& Kauai: Station 8989, 388-500 fathoms (Cat. No. 

 22561, U. S.N.M.); Station 4013, 399^19 fathoms; Station 4030, 

 423^38 fathoms (Cat. No. 25376, U.S.N.M.) ; Station 4182, 671-957 

 fathoms (Cat. No. 25375, U.S.N.M.). 



The species were secured by the Siboga Expedition in the Celebes 

 Sea, o& Menado, 1,26^1,165 meters; Kei Island, 204 meters; Arafura 

 Sea, 984 meters. 



STACHYODES BOWERSI, new species. 

 Plate XLIII, figs. 5, 6 ; plate XL VIII, fig. 2. 



Colony about 225 mm. high. Basal portion white, solidly calca- 

 reous except at the center of axis ; eight erect branches are given off 

 immediately above the base, all of which shortly divide into three 

 erect branchlets, some of which continue without further division, 

 but most of which again branch dichotomously. All of the branches 

 are erect and approximately parallel. 



The calyces are in whorls of four, and face downward, each calyx 

 bearing a series of whorls of broad scale-like spicules, two to a whorl, 

 each whorl being strongly frilled and dentate on its outer (lower) 

 margin, each being costate in a longitudinal direction, and each 

 whorl overlapping its successor. One scale of each pair also over- 

 laps its fellow laterally. The first, or upper whorl, is much broader 

 in its dorsal part, narrows beneath into a mere collar or rim, and 

 distally expands into a broadly frilled margin with four to seven 

 jagged uneven teeth. 



The second (middle) whorl is incomplete on its inner side, and its 

 outer side is shorter than that of the first whorl ; it ends in a frilled 

 expanded margin in which the teeth are less prominent than in the 

 first whorl. The third (distal or lower) whorl is the largest, and the 

 margin is conspicuously frilled and dentate, or rather lobular, the 

 teeth being less pointed than in the first whorl.
