double-clubs. The following are the chief types, with inoasurements, length 

 by breadth, in miUimetres : — 



(1) Double-clubs with a very long constriction and with almost 

 hemispherical ends. The warts are almost smooth; they are 

 openly disposed and arranged almost in whorls : 0-068 x 0-0.^4 ; 

 0-061 X 0-03 ; 0-057 X 0-027. 



(21 Elongated double-clubs passing to double-spindles. There is a very 

 distinct constriction ; and the ends are markedly conical. The 

 warts are not closely set, and are almost smooth : 0-114 x 0-02.3; 

 0-103 X 0-023 ; 0-095 x 0027 ; 0-095 x 0-023. 



Irregular forms, crosses, and scales from the tentacles also occur.

To show the varied appearance of the venucae, we have included here 

 three figures of specimens of Scirpearia fla(j<'U ii,m in the Monaco Museum. ■

We have no hesitation in establishing this new species for a .specimen 

 which was originally referred to the species JumcUa elongnta by Thomson 

 and Henderson, who were compelletl to base their diagnosis on the very 

 inadequate description of this species which was available at the time of 

 publication of the Indian Ocean Deep Sea Alcyonaria Peport. At that time 

 the spicules of Scirpearia elongata {Juncella clongafa) were unknown; but an 

 investigation of the spicules of an old specimen in the Museunj of the lioyal 

 College of Sui'geons, and the consequent resuscitation of that old but 

 imperfectly known species has caused the necessity of i-emoving the present 

 specimijn. 



The colony shows several very characteristic features : for example, 

 (1) the nature of the branching, (2) the marked rigidity of the colony, 

 (3j the nature of the verrucae ; but most of all the distinctive character 

 of the spicules, which mark it off as a very definite and new .species. 



The specimen is 22 cm. iu height, and is branched appro.ximately in 

 one plane. The branching is alnmst dichdtomous; and tlie silhouette of the 

 axis (tig. 61,1 gives the essential features. On the wiiole, the colony is very 

 rigid, owing to the very densely calcareous nature of the axis. The coenen- 

 chyma is moderately tliin, \mi densely spiculose ; the general colour of the 

 colony is salmon-pink.
