THE ALCYONARIA OF THE MALDIVES. 539 



Fig. 25. Group of rudimentary siphonozooids of same species. Surface view of stained preparation. 

 X 90. Thie drawing shows the degenerate stomodaeum with mouth aperture (Cam. Luc). 



Fig. 26. Sclerophytum pahiuitum sp. nov. Drawing of a colony to show branching of capitulum. 

 Many of the autozooids are expanded. Natural size. 



Fig. 27. A tentacle of autozooid of same species, showing double row of rudimentary pinnules 

 down each side, (x 60 Cam. Luc.) 



Fig. 28. Sclerophytum gardineri sp. nov. Drawing of a colony. x 2. The colony is laterally 

 compressed and is irregularly cup-shaped, with lobes arising from the middle and edges 

 of the cup. The autozooids are small and are not numerous. Siphonozooids are absent. 



Fig. 29. Sclerophytum durum sp. nov. A lobed colony, x 1^. All the autozooids are retracted. 

 The enormous spicules characteristic of this species can be seen through the ectodermal 

 tissues of the capitulum. They are also shown protruding from the base of the stalk. 



Fig. 30. A younger cup-shaped colony of same species with rhizome-like outgrowth from the stalk, 

 x 2. A few very small lobes are seen arising from the basin of the capitulum. The 

 autozooids in this specimen are apparently most numerous round the margin of the 

 capitulum. 



Fig. 31. Tuberculate spicules of same species. a. A single tuberculate spindle, x 10. h. A 

 portion of the tuberculate surface of the same spicule, more highly magnified, x 80. 

 c. Tip of a more pointed spindle showing tuberculate warts, x 8. d. x 6 (Cam. Luc). 



Fig. 32. Spicules of same species; numerous near surface of colony, a, h, c, d, e. Different forms 

 of clubbed spicules. All these forms are common, a, b, c, x 290, d, x 270, «, x 250. 

 / An irregular tuberculate dumb-bell (rare), x 270. g. An irregular spindle with small 

 spines, x 250. 



Fig. 33. Sclerophytum querciforme sp. nov. A colony with a secondary stalk and capitulum. x 2. 

 The large tuberculate spicules are seen protruding from the base of the stalk. The stalk 

 is branched at the top and passes almost imperceptibly into the capitulum.
