REPORT ON THE GORGONACEAN CORALS. 153 



Depth 40-90 fathoms. 



This form differs from A. arbuscula, A. alternans Wright & Studer, 

 A. acanthostoma and A. fruticosa Germanos, in the structure of the 

 polyps, their proportionate size to the width of the branch, and the 

 shapes of the spicules. The spicules resemble most closely those of 

 A . acanthostoma, but the polyps of the new species are much more 

 spiny. 



Acanthogorgia muricata Verrill. (Plate XII. Figs. 6, 7.) 



Verrill (4) gives no figures, but the specimen agrees fairly with his 

 description of the species. 



The branching is in one plane. 



Height of the specimen 75 mm. ; breadth 8 mm. ; diameter at the 

 base 1 mm. 



Length of the calyces 2*0-2 - 5 mm. ; diameter at the base '6 mm. ; 

 diameter of the head 1*2 mm. 



The spicules round the edge of the calyx are D01 x -06 mm. ; the 

 spicules of the calyx-wall are "75 x "03 mm. ; the spicules of the 

 coenenchyma are '3 x -03 mm. Most of the spicules are crooked, and. 

 some have the smaller end slightly branched. 



Depth 40-90 fathoms. 



Previously recorded from Barbados. Depth 76 fathoms. 



This is a good example of wide distribution, the same species being- 

 found at Barbados and at Funafuti, two widely separated localities. 



VlLLOGORGIA INTRICATA Gray. 



There is one example of this species attached to the axis of a dead 

 Gorgonid. Wright and Studer (7) describe the species among the 

 ' Challenger ' Gorgonidse. 



Depth 40-71 fathoms. 



Previously recorded from a locality between the Fiji Islands and the 

 New Hebrides. Depth 145 fathoms. 



This is a considerable difference in depth, but the specimen is 

 undoubtedly V. intricate. 



Villogorgia rubra, ii. sp. (Plate XIII. Figs. 1, 2, 3, 4.) 

 There are two small colonies with much of the coenenchyma 

 rubbed off.
