The spicules of Chironephthya maorospiculata, n. sp., are of unusually large 

 dimensions, some attaining a length of 8 '3 mm. (See Plate IV. tig. 10.) 



In Spongodes uliginosa, n. sp., there are almost equally huge spicules, some 

 8 mm. in length. 



Noteworthy is the great heterogeneity of the spicules in some of the forms, 

 e.g. plates, discs, triangles, rods, spindles, and "golf-clubs" in Acanthomuricea 

 spicata, n. sp., and similarly in A. ramosa, n. sp. 



Besides the very peculiar habit, incrusting a huge siliceous rod, there are 

 many interesting features in Sarcophytum aberrans, u. sp. : the occurrence of 

 several sizes of autozooids, the inturniug of almost the whole of a large tentacle 

 into the stomodaeum, the presence of ova and embryos in the siphonozooid canals. 



In SarcophytMm agaricoides also there are ova in the siphonozooid cavities. 



The dimorphism which Gray recorded in his Paragorgia nodosa is confirmed 

 iu P. splendens, n. sp. It is unique in Pseudaxonia. 



In Distichoptilum gracile, Verrill, we have observed that there may be two 

 or three siphonozooids in close connection with the autozooids. 



The complex differentiation of the polyps in Agaricoides alcocki, Simpson, 

 is quite unique. 



Very remarkable tentacles occur in Thesioides inermis, n. g. et sp. (See 

 Plate VI. figs. 1 and 2.) Those of Protocaulon indicum, n. sp., are also unusual 

 (See Plate VII. fig. 3.) 



The base of Anthoptilum decipiens, n. sp., is very characteristic in its shape, 

 and it may be further noted that there is no evidence of an area of attachment. 



In Pteroiiides triradiata the small number (3) of supporting rays is note- 

 worthy. It is possible that the specimen, which is only 107 mm. in length, is still 

 young ; and attention may be directed to the range of variation in the number of 

 rays in P. griseum. 



In regard to a collection which is a very feast of colour, we may call special 

 attention to the exquisite colour schemes of Pennatula veneris, P. pendula, and 

 P. splendens, and also to the very rich crimson-lake tint of the rachis and 

 pinnules in P. indica. 



The presence of numerous Foraminifera in the stomodseum of Agaricoides 

 alcocki is a fact of interest. 



Some of the epizoic animals are interesting, e.g. the peculiar Solenogaster 

 (Rhopalomenia gorgonophilaV) on Acamptogorgia circium, n. sp. ; Palythoa and 

 sponge on Parisis indica, n. sp. Between the vegetable axis and the stolons of 

 tiympodium indicum, n. sp., Polychset worms have formed burrows, and some 

 tube-forming Polychsets are attached to the surface.
