DEVONSHIRE CUP-CORAL. Curyophyllia Smithii. TUFT-CORAL. Lopho]MHa prolifera. 



(With side buds. ) ENDIVE-CORAL Euphyllia pavonia TREE-CORAL -Dendroyhyllia nigrescent 



DEVONSHIRE CUP-CORAL. (And skeleton.) 



Another specimen, weighing six pounds, has been taken in a similar manner between the 

 islands of Bum and Eig. As may be seen from the illustration, the corallium resembles 

 a massive, thickly-branched tree. The individual corals are about half an inch in height 

 and the same in diameter. 



On the right hand of the illustration is seen a coral that has attained a singularly 

 tree-like form, and, in consequence of this structure, has obtained the appropriate name 

 of Dendrophylli'a. 



The regular branched form of this coral can be seen by reference to the illustration, 

 together with the manner in which the individuals are set on their common stem. The 

 cells are rather deep, and the animals possess tentacles which are cleft longitudinally. 

 It is a native of the hotter seas. 



ON the accompanying illustration we have some examples of those beings which we 

 call Madrepores. 



In the genus MADREPORA the animals are rather short, with twelve simple tentacles. 

 The cells are deep, irregularly arranged upon the surface, and are crowded together 

 towards the tips of the corallium, though they are scattered rather widely at its base. 

 The cells are nearly cylindrical in their general shape and project outwards from a centre, 

 something like the grains on an ear of wheat. 



The genus Echinopora is distinguished by the peculiar arrangement of the cells, which 

 are set only upon the upper surface of the coral. They are boldly radiated and rather 

 irregular. All the true Madreporse inhabit the hot seas, and are most plentiful under 

 the tropics. 



In the lower left-hand corner is seen a specimen of the genus ASTR^EA, so called 

 because the animals are sown over its surface like stars in the heavens. The cells are 

 decidedly short, and the tentacles few in number. The genus is a very large one, 

 including many recent and fossil specimens, many of which are familiar to us in the 

 polished stones of which mantelpieces and other domestic ornaments are made. Owing
