The primary and secondary septa are straight. Their upper margins lie 

 at a lower level than those of the remaining septa, and are only very 

 slightly toothed. The primary septa are free from adherence. The 

 margins of the tertiary, quaternary, and quinary septa are deeply dentate, 

 the teeth being curved towards the columella. The quinary, quaternary, 

 and tertiary septa fuse with one another laterally and by their upper 

 margins at successive distances from the periphery of the corallum, 

 forming six deltoid masses of septa. The tertiary septa, forming the 

 sides of these deltoid masses, are bent over, sloping away from the pri- 

 mary septa, so that at the apex of the delta the upper margins of these 

 tertiary septa fuse and cover over the inner ends of the secondary septa. 

 There is no separation of the septal interspaces into chambers, as in S. 

 florealis, by development of synapticulse ; but the quaternary and quinary 

 septa are more or less bent over above, so as to fuse along part of their 

 upper margins, and roof in. the spaces between them. The septa cor- 

 respond to the interspaces between the costre. The columella is a large, 

 oval, spongy mass composed of fine trabecule. 



Measurements of the largest specimens : extreme diameter 3*9 centims. ; 

 extreme height 1*1 centim. Other specimens measure in diameter about 

 2- 5 centims. and 2 centims. 



This coral was obtained near the Ke Islands together with S. compli- 

 cate, and also found living with Euplectella aspergillum at Cebu, Philip- 

 pines, in 95 fathoms. Several living specimens have been preserved in 

 spirit for future examination of the soft parts. In the living animal the 

 disk is of a madder- red colour, much darker towards the margin of the 

 calicle. The tentacles are simple and conical ; the inner are white with 

 dark madder tips, and the outer of a light madder colour with vivid 

 emerald-green radial stripes on either side of their bases. The margin 

 of the mouth is white. The corallum is conspicuously white, the fleshy 

 coloured parts of the coral not extending to the very edge of the calicle. 

 A white zone thus sets off the dark-coloured central parts of the coral. 



Fungia symmetrica, Pourt. 

 This species of Pourtales's has been proved by our dredgings to be one 

 of the most constantly recurring deep-sea animals with a world-wide 

 distribution. As will be seen by reference to the list of localities, it has 

 been dredged by us 15 times. It occurs in the North and South Atlantic, 

 near the ice-barrier in the S. Indian Ocean, off the West Indies, in the 

 North and South Pacific Oceans, and amongst the Moluccas. It has a 

 more extended range in depth than almost any other animal, having been 

 obtained by us in 30 fathoms off Bermuda, and at all intermediate depths 

 down to 2900 fathoms. Specimens from 2900 fathoms were obtained 

 with the soft parts preserved, and specimens from 2300 fathoms, of which 

 30 or more were obtained at one haul, were full of ripe ova. Fungia 

 symmetrica is, further, the only coral which has been as yet obtained
