The following is a list of the chief types with their measure- 

 ments (length by lireadth iu millimetres) : 



I. Ccenenchyma: 



1 Spindles, very thick with close-set warts. (0-046 X 



0-019; 0-04() X 0-015; 0-042 X 0-019.) 



2 Short, stumpy spindles, densely warted. (0-027 X 



0-019; 0-027 X 0-015; 0-023 x 0-015.) 

 3. Almost spherical warty forms. (0 - 019 x - 019 ; • 015 

 X 0-015; 0-012 X 0-012.) 

 II. Polyps: 



l" Long thick spindles, with fewer and longer warts than 

 in (a) of the ccenenchyma. (0 - 053 x"0 - 012 ; - 046 

 X 0-015.) 



2. Spindles with very few long warts. (0-042 X 0-011 ; 



0-038 X 0-015.) 



3. Spindles, still shorter, and with fewer warts. (0 - 031 



X 0-015; 0-027 x 0-012.) 



4. Flat, irregular scales from the verrucae. (0-034 x 



0-015; 0-031 X 0-011.) 



5. Crosses. (0-038 x 0-019; 0-031 x 0-031.) 

 Locality : — Cape Morgan, X.N.E. 9 J miles ; depth, 47 fathoms ; 



bottom, broken shells (25. vii. 01). Previously recorded from Cape 

 Morgan, 32° 45' 45" S., 28° 26' 15" E. ; 36 fathoms ; stones (12. i. 01).

To this new species we refer two small complete specimens and 

 a portion of a much larger specimen from the Cape. The longer 

 complete colony is 20 cm. in length and the shorter is 12 cm., 

 while the length of the broken portion is also 20 cm. The first 

 specimen has a maximum breadth of 2 mm. ; the second is about 

 the same size ; the fragment is 3 mm. in breadth. 



The ccenenchyma is extremely thin in all the specimens, and 

 in the non-polyp-bearing part the dark axis is easily seen through 

 it. It is densely spiculose and extremely brittle, especially when 

 dry. The surface is very arenaceous in appearance. 



The axis is comparatively soft; it is composed of concentric 

 laminse, which consist of a horny substance in wliich calcareous 

 matter is deposited. 



From end to end of the colony there runs a streak devoid of 

 polyps and occupying about one-third of the circumference of the 

 stem. The polyps occur densely packed on the remainder of the 

 circumference ; these project laterally and so add to the breadth of
