The entire body. From the margin of the cap-shaped shell arise six 

 ascending arborescent feet and six alternating descending feet, 

 which are covered with anchor-pencils and branched at the distal 

 end. From the mouth of the delicately alveolate shell depend 

 prominent parts of the dark voluminous phseodium. 



Fig. 2. Gorgonetta mirabilis, n. sp., . . . . x 300 1674 



The distal end of an ascending foot; the branches bear a terminal 

 spathilla with small recurved teeth. 



Fig. 3. Gorgonetta mirabilis, n. sp., . . . . x 300 1674 



The distal end of a descending foot, with three lateral anchor-pencils and 

 three terminal branches (broken off). One alveole contains an air- 

 bubble. 



Fig. 4. Gorgonetta mirabilis, n. sp., . . . . x 600 1674 



A single thread of an anchor-pencil, with two quadridentate spathillse, a 

 larger proximal and a smaller distal (terminal).
