and 4 cm. in diameter; both of the specimens were to some 

 extent concealed by a growth of Porifera and Polyzoa. 



Rough transverse sections through a branch show the 

 yellow circular axis in the centre, and surrounding this, three 

 or four cavities contaming the anthocodiae. These cavities are 

 closely protected by spicules which extend inwards towards 

 the axis, but do not invest the latter. The anthocodiae are 

 completely retractile within the calyces, and the tentacles are 

 marked out by prominent narrow, red spindles, which differ 

 from those of all other parts of the specimen. 



The spicules of the outer and inner coenenchyme, and of 

 the calyces, are similar m shape. They have the following 

 forms and dimensions in millimetres: — (i) spindles, with five 

 transverse rows of broad tubercles, about o. 12 x 0.04; (2) 

 spmdles of about the same size, but instead of broad tubercles 

 having simpler spines or i;)rocesses ; (3) spindles of the first 

 kind, but with only two rows of broad tubercles, and measur- 

 ing about 0.08 X o.oA: (4) double wheels (only a few), .04 x 

 .06; (5) a few crosses or stars, and double crosses; (6) long, 

 narrow spindles of the tentacles, with simple processes, about 

 0.26 x 0.02. The spicules of this specimen are difficult to 

 classify, they vary so much. 



In spite of the difference in colour and some other points, 

 I identify these specimens as young forms of Eugorgia Gil- 

 christi, Hickson. They were found at the same depth, and in 

 similar ground to those of Hickson.

This descri])tion is based on six white specimens. The 

 branching is in one plane, but neither dichotomous nor regular. 

 The axis is thick, horny, non-calcified, brown or black in 

 colour, and the coenenchyme covering it is thin. Longitu- 

 dinal slightly wavy lines occur on the surface of the coenen- 

 chyme of the lower and chief shoots, which are only slightly 

 de'veloi>ed on the upper branches. Anastomosis is rare, l^eing 

 confined to only a few of the branches. The upper branches 

 of the colony arc slightly flexible, and their axes when stripped 

 of the white coenenchyme, yellow in colour. The calyces of 

 the polyps occur only as very minute elevations, and the latter 

 are not numerous near the base of the coloriy. The 

 lower main branches arc slightly flattened, but the apical are 

 rounded; on the flattened ones the polyps are slightly more 

 numerous on the narrowed sides. On the more flattened basal 

 In-anches, the number of longitudinal lines appears to be about 

 £lvc in number, higher up this number decreases, and the polyps
