40 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 1 



Remarks. — The nearest relative of this sponge appears to be E. angu- 

 lospiculata from the Gulf of Mexico, which, however, has a bright yellow 

 endosome. The larger spicules are strongyloxeote at one end or at both 

 ends. The smaller spicules are also much larger than the corresponding 

 categoiy in the new species, while the larger range is considerably shorter.
