174 THE VOYAGE OF H.M.S. CHALLENGER. 



rows, seven of which may be counted from one aspect of a branch. The members of a 

 row are under one length apart in the case of the longer spines. Towards the base of a 

 branch the disproportion in size is much more marked than is shown in the figure (PL XL 

 fig. 24), those on one side becoming quite short and pointed, whilst those on the opposite 

 side retain their normal size. 



Habitat.— Cape Palmas (Hooker), Brit. Mus. (Reg. No. 43.2.3.110). 



Var. minor, nov. (PI. II. fig. 9). 



Stem and mode of branching unknown. Branches bearing straight branchlets from 

 7 to 9 cm. long, forming a wide angle with the stem. These are clothed from near the 

 base to the apex with a short, much divided set of pinnules, which are subequal in 

 length, giving a bottle-brush form only T25 cm. in diameter. The pinnules are short, 

 arranged spirally, and stand out nearly at right angles to the branchlet ; they are much 

 flattened and bifurcated near the base, each portion having two to five secondary lateral 

 pinnules arranged alternately, from 1*5 to 6 mm. long, the longest of which have 

 occasionally a short tertiary pinnule placed on the outer antero-lateral margin (PL II. 

 fig. 9). 



The spines have a similar arrangement to that in the type specimen of Antipathes 

 spinescens, Gray. Colour of the sclerenchyma greyish olive. 



Two branchlets only were found in the British Museum Collection along with 

 Antipathes spinescens, Gray, and labelled Antipathes spinescens in Gray's handwriting. 

 This form is, however, distinguishable at a glance from Gray's type. 



Habitat. — Not recorded, but possibly not the same as the type, as it was obtained 

 five years later. Brit. Mus. (Reg. No. 48.8.32.2). 



[Antipathes] squamosa, Koch. 



Antipathes squamosa, W. Koch., Neue Anthozoen a. d. Golf. v. Guinea, p. 9, pi. ii. fig. 5, 

 1886. 



Koch's type consisted of a specimen with two stems arising from the same base, 

 19 and 21 cm. in length respectively. The shorter one was almost without branches, 

 the longer, in its upper portion (12 cm.), bearing a number of branches having almost 

 the same diameter as the stem. The branches come off in all directions, giving a bottle- 

 brush form, tapering somewhat above. The branches have the following arrangement : — 

 A main branch (1) bears one, two, or, more rarely, three secondary branches (2), which 

 in their turn may bear branchlets of a third order (3). All the secondary branches are 

 borne on the same side of the primary ones, and are directed downwards. The branches
