THE ALCYONARIA OF THE MALDIVES. 537 



Fig. 2. Surface view of a portion of the capitulum of the same species showing two autozooids, 

 one expanded, the other contracted. Small spicules are seen imbedded in their walls. 

 Spicules are also numerous in superficial tissues between the zooids and are seen by 

 transparency of the ectoderm. The mesenteries of the siphonozooids may be seen through 

 the ectodermal tissues, x 20. 



Fig. 3. Sarcophytum glaucuin. A ciliated canal connecting the coelenteric cavity of an autozooid 

 with that of a siphonozooid. x 300. Running at right angles to the ciliated canal is 

 a longitudinal canal of the internal canal system, which in tlie preserved condition 

 appears to be unciliated ; this canal also opens into the coelenteric cavity of the autozooid. 



Fig. 4. Group of rounded golden cells in same species with granular yellow contents in internal 

 canal system, x 620. 



Fig. 5. Sarcophytum plicatum. Spicules, x 60. (This species was not in the collection, but the 

 drawing is inserted because the spicules are tuberculate and approach Sclerophytum 

 in form.) 



Fig. 6. Sarcophytum tenuis sp. nov. Spicules, x 120. a = a slender spindle to be found in the 

 coenenchym and on the anthocodia of the autozooids. h = slender clubs from the 

 coenenchym. c = small club to be found in the periphery of the capitulum and in 

 the stalk. 



Fig. 7. Lohophytum paucijlorum. A colony characteristic of the genus, x 2. As all the specimens 

 in the collection of fairly large colonies are fragmentary, a drawing was therefore made 

 of a complete specimen from New Britain, which agrees with the specimens from the 

 Maldives in all essential details. The lobed appearance of the capitulum is due chiefly 

 to the formation by budding of new autozooids at any portion of the capitular surface. 

 In this genus the siphonozooids are most numerous on the marginal seam of the 

 capitulum. The marginal lobes differ from the inner lobes in the proportionately greater 

 number of siphonozooids compared with the number of autozooids on their surface. 



Fig. 8. Sclerophytum capitals sp. nov. A complete colony. x 2. Many of the autozooids are 

 fairly expanded. 



Fig. 9. Sarcophytum, tenuis sp. nov. x 1 J. Only the upper surface of the slightly concave capitulum 

 is shown. Autozooids are very numerous round the margin forming a thick fringe. In 

 the middle of the capitulum they are much fewer in number. Siphonozooids are indicated 

 as dots between the autozooids, they are much more numerous in the actual specimen. 



Fig. 10. Sarcophytum roseum sp. nov. Spicules, x 120. The spicules are slightly zonate, and in 

 this respect approach Lobophyfiun. I, ii, ill are taken from near the surface of the 

 capitulum, iv, v, vi and vii from the coenenchym of the capitulum. 



Fig. 11. A portion of the capitulum of the same species, x 1J-. All the autozooids are contracted. 

 The capitulum is thickest in the middle and thins out towards the margin, and therefore 

 has no capitular fold as in " ehrenbergi" (tig. 1). Siphonozooids are indicated as small 

 dots between the autozooids. 



Fig. 12. Lohophytum paucijlorum. Young mushroom-shaped colony, x 2. 



Fig. 13. Surface view of tip of lobe of capitulum of same species, showing three autozooids and 

 surrounding siphonozooids. x 30. One autozooid is fairly expanded.
