V. '07. 25 



Three living specimens of this beautiful coral were taken. 

 Two are perfect, but the third is broken across. In the Irish 

 specimens the quinary septa are not quite so prominent, nor 

 so regularly developed as in the type. The largest specimen 

 has a diameter of 62 mm. ; the two smaller ones measure 

 50 mm. across. 



S. diadema resembles in general shape S. moseleyanus, 

 Sclater (Proc. Zool. Soc., 1886), but differs from it in the 

 arrangement of the septa. One specimen of S. moseleyanus 

 was taken by the Triton between the Faroes and Hebrides, and 

 was the first, and, up to this, the only example of this genus 

 dredged in British seas. 



Stephanotrochus diadema w^as first taken by the Challenger 

 off the Azores and off Brazil. It has since been found by the 

 Hirondelle at the former locality, and has also been obtained 

 off Guadeloupe.

This species is represented by several large specimens. It 

 has previously been found at many points off the Irish coast. 

 Its geographical distribution is wide, and it has been recorded 

 off the eastern and western coasts of the North Atlantic, in 

 the South Atlantic, in the Indian Ocean (as Caryophyllia coin- 

 mums, Seg.), and off the East Indies.
