 body proper, 75 mm. in length of tail, 45 mm. in width of body. 

 Minute dorsal papillse 4-8 in each row. Pedicels of the lateral margin

Station 5084. Twenty-three specimens. 

 Length of body up to 210 mm., breadth 85 mm. Pedicels of the 

 odd ambulacrum about 35 pairs, varying 25-40. Lateral brim with 

 about 45 pedicels. Dorsal papillae in most cases 4 or 5 to each side, 

 but sometimes 6, posterior ones very often of considerable size. In 

 one individual the posteriormost one is 20 mm. long and 10 mm. in 

 diameter at base, in others quite small, being only 5 mm. long and 

 2.5 mm. across. The large unpaired papilla is also very variable in 

 size as well as in shape. It may be 40 mm. long and 25 mm. broad. 

 In only 3 of the 23 specimens is this papilla single-pointed (text-fig. 

 D) ; in another the bifurcation is only slightly indicated at tip (fig. C); 



1 The spicules represented in figs. 5 and 6, pi. 35, are those of an Atlantic specimen which is referred by 

 Perrier to E. auriculata.
