4S MISS ISA L. niLEs ox GORGONACBAN'. [Jan. 17, 



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

 Stuclt^r, A. acantliostoma and A. fruticosa Grermanos, 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. aeanthostoma, but the polyps of the new 

 species are much more spiny. 



AcANTHOGORGiA MURiCATA Verrill. (Plate I. 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 aim. ; breadth 8 mm. ; diameter at 

 the base 1 mm. 



Length of the calyces 2"0-2'o mm. ; diameter at the base "G mm. ; 

 diameter of the head 1'2 mm. 



The spicules round the edge of the calyx are 1-01 x "06 ram. ; 

 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 slightlv branched. 

 O 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. 



ViLLOGORGIA 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 ' Gorgouidse. 

 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. intricata. 



ViLLOGORGIA RUBRA, n. sp. (Plate II. figs. 1, 2, 3, 4.) 



There are two small colonies with much of the coenenchvma 

 rubbed off. 



The basal attachment is present in both as a small, flat, 

 calcareous expansion. 



One colony gives off a broken branch at an angle of 90°, 10 mm, 

 above the base ; the main stem reaches a height of 40 mm., and 

 13 mm. from the apex gives off another branch at the same side, 

 8 mm. long. 



The other colony is 34 mm. high and gives off three branches 

 fairly perpendicularly. These are all on the same side; the 

 lowest arises 11 mm. froai the base and is broken off short ; 

 the second is 9 mm. long, and arises 3 mm. above the first; the 

 third is 4-5 mm. above the second, and is 13 mm. long. 



There are very few polyps, most of the coenenchyma having
