Fam. Axinellidae. 



Genus Higginsia Higgins. 

 Higgiiisia pyriformis nov. spec. 



Sponge small, pear-shaped, with a long slender stalk; the whole 

 length barely 10 mm., the corpus itself 3 mm. by 2 mm.; diameter of 

 stalk ca. 0,3 mm. Osculum at the top of the sponge, diameter ca. 

 0,4mm.; a delicate transparent dermal membrane covers the body; 

 color yellowish-brownish, stalk, however, white and clear on account 

 of the small amount of organic matter found in it. The skeleton 

 composed of spiculo-fibres ascending from the base, forming the stalk, 

 ending at the summit, and forming a little spiculo-fringe surrounding 

 the osculum. 



Spiculation: Of the known Higginsia species H. pyriformis 

 mostly resembles H. Thielei Topsent as to the spiculation. But in H.
