ALCYONAEIA WHITELEGGE. 223 



The spindle-shaped spicules on the stem and branches are large, 

 numerous, and easily visible to the unassisted eye ; those on the 

 main stem are arranged more or less transversely, varying greatly 

 in size, and are much more strongly spinose than the longitudinally 

 disposed spicules of the branches. 



The colour is yellowish-white, the branches and polyps are 

 dark reddish-purple. The larger spicules often attain to a length 

 of 6 mm. 



SUB-FAMILY SIPHONOGORGIN^. 



SlPHONOGORGIA GODEFFROYI, Kolliker. 



Siphonogorgia godeffroyi, Kolliker, Wright & Studer, Chall. 

 Rep., Zool., xxxi., p. 236, pi. xxxviii., fig. 4. 



There are two small broken specimens which I refer to this 

 species, the larger of which is 25 mm. high and 5 mm. in diameter; 

 the apex is wanting, the remaining portion consists of an erect 

 stem giving off eight very short branches with terminal polyps. 

 The stem is pinkish at the base, the upper part white, and the 

 polyps very dark red. The longitudinally arranged spicules are 

 large, and consist of straight or curved tuberculated spindles. 

 Size 3- by '3 mm. 



Obtained at a depth of from 40 to 70 fathoms. 



SIPHONOGORGIA PALLIDA, Studer. 



Siphonogorgia pallida, Studer, Chall. Rep., Zool.> xxxii., p. 8, 

 pi. ii., fig. 2 <z, b. 



One example preserved in formol, in a much broken condition, 

 the actual base is wanting and the upper terminal twigs are 

 reduced to fragments. 



The colony notwithstanding its damaged condition is 130 mm. 

 high and 70 mm. wide, the main stem is laterally compressed, its 

 widest basal diameter is 8 mm. and its narrowest 5 mm. 



At a short distance from the base a large secondary branch 

 arises, which is slightly less robust than the primary, the general 

 appearance is like the figure on pi. ii. of the Chall. Rep., but the 

 main and secondary branches are more undulate. 



The polyps on the lower parts of the colony are in many 

 instances quite flush with the surface, very few projecting like 

 those on the slender twigs. 



The colour is bright brick-red with yellow polyps.
