at the base ; (b) spindles covered with irregular warts ; 

 (c) spindles bearing in addition to warts a number of smooth 

 projecting spines on one side ; (d) irregular forms with warty 

 branches on one side and smooth spines on the other ; (e) bi- 

 furcate spindles ; (/) irregular plates with warty branches ; 

 and (g) smooth spindles in the anthocodiffi.

The specimen from Catch differs from the type in the 

 following particulars : — It is unbranched (65 mm. in height, 

 with a diameter of 3 mm.) ; it is more delicate in appearance 

 a!id lighter in colour ; the large pointed spicules surrounding 

 the mouth of the verruca are pink to white, instead of deep 

 red ; the ground-colour of the ccBnenchyma is white, instead 

 of red or pink ; the spicules are more delicate and bear longer 

 spines ; tlie superficial spicules of the ccenenchyma are white 

 spindles with prominent rough warts, and reaching dimensions 

 of 0"61 xO-19 mm., wiiile the corresponding spicules in the 

 type are thick red spindles with short close-set warts, and of 

 larger size, viz. 0'91 x0"23 mm.

(6) Lophogorgia lutkeni, Wright and Studer. — The repre- 

 sentatives of this species are much larger and more copiously 

 branched than those described in the ' Challenger ' Report ; 

 the largest specimen reaches a height of 45 cm. and the main 

 stem has a diameter of about 7 mm. The verrucaj show 

 eight triangular marginal lobes bent over the retracted 

 tentacles, and it is of some interest to note that while the 

 venucEe of some branches stand out to a height of 1 mm., the 

 openings on other branches are flush with the general surface 

 of the ccenenchyma. 



Locality. Off Beyt Island, 3-4 fath. 



(7) Juncella juncea (Pallas). — Unbranched and slightly 

 branched colonies, yellowish wliite (with a touch of red) to 

 buff in colour, with very crowded verrucas without definite 

 arrangement. The spicules are clubs and double stars, inter- 

 mediate forms between clubs and double stars, and a few single 

 stars. We have referred the specimens to J. juncea rather 

 than to J. gemmacea because the former is the older species. 

 Prof. Hickson has suggested that J. juncea and J. gemmacea 

 should be united in one rather variable species, and a study 

 of various representatives of Juncella has led us to the same
