both surfaces granulose, with radiathig stiis^, edges finely 

 seriated. 



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

 slender microxea 40x1 /m. 



Small chiasters 10 yu 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 orthotriajnes. In T hide's species 

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

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

 with long rhabdomes 500 /x in lengtii, but only aborted 

 forms.

The specimens of this species ramify in fragments of 

 Echinojjora along with Dyscliona Davidi, and in a lamina of 

 Agoricia along with Cliona mucronata, Sollas. Colour 

 purple. 



One of the two kinds of spinispirulas is 54 X 1'5/a, slender, 

 with eight or more curves and with separate short blunt 

 spines, the other kind being much stouter, 48 x 6 /x, with 

 about six bends and with sharp pyramidal spines. 



The tylostylcs are3G0x4/i, 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.

Boring sponges of orange-yellow colour. Oscular papillae
