both surfaces granulose, with radiating stria?, edges finely 

 serrated. 



Microxea (medium) 80x3 fi } slightly curved. Very 

 slender microxea 40 X 1 /a. 



Small chiasters 10 /a in diameter, with small centrum and 

 about 12 slightly tylote rays. 



Oxyasters 18-30 fi in diameter, with about 6 rays. 



The new species is near E. placenta, Thiele (27, p. 5, pi. i. 

 fig. 1, pi. vi. figs. 1, a-h), but differs from it chiefly in the 

 proportions of the oxea and orthotriames. In Thiele's species 

 the oxea attain a size of 800 //,, and the microxea are centro- 

 tylote. Further, in the new species there are no orthotrisenes 

 with long rhabdomes 500 fx in length, but only aborted 

 forms.

The specimens of this species ramify in fragments of 

 Echinopora along with Dyscliona Davidi, and in a lamina of 

 Agaricia along with Cliona mucronata, Sollas. Colour 

 purple. 



One of the two kinds of spinispirulas is 54 X l'5fi, slender, 

 with eight or more curves and with separate short blunt 

 spines, the other kind being much stouter, 48x6/*, with 

 about six bends and with sharp pyramidal spines. 



The tylostyles are 360x4 fi, straight or slightly curved, 

 with oval or spherical heads about 7 fi in diameter, but 

 showing a certain amount of variation in shape and size.
