The spicules of Chironephthya maot-ospiculata, n. sp., are of unusually large 

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



In Sjyongodes nligmosa, 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. ramona, n. sp. 



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

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

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

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



In Sarcophytum aga7-icoides also there are ova in the siphonozooid cavities. 



The dimorphism which Gray recorded in his Paragorgia nodosa is confirmed 

 in P. splendens, n. sp. It is unique in Pseudaxouia. 



In Distichoptilmn 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 inermi'i, n. g. et sp. (See 

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

 (See Plate VII. fig. 3.) 



The base of Anthopdilum decipicns, 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 Pteroeides 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 

 [Rliop>alomenia gorgonophilal) on Acamptogorgia circium, n. sp. ; Palytlioa and 

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

 Sympoditim indicum, n. sp., Polychaet worms have formed burrows, and some 

 tube-forming Polychsets are attached to the surface.
