The general form of body varies, of course, with degree of contrac- 

 tion. In well expanded specimens dorsal surface is rather high and 

 the lateral interambulacra are rather rounded. In a natural state the 

 specimen shown in tig. 1, Plate LXXIII would be considerably longer. 



The large pedicels appear to be pretty constantl}^ 17 to a side for 

 medium-sized individuals and 19 to 23 for the larger ones. In pre- 

 served specimens they arc unequal in length, the longest being 33 mm. 

 in type. Those near anterior extremity are longer than the more 

 posteriorly situated ones. Lateral papilh^^ in type are longer than 

 pedicels, 17 and 18 in number, to two sides respectively (pedicels 20). 

 In many small, specimens they are quite short and rather distantly 

 spaced, the difference being not altogether due to contraction. 

 Smallei- specimens with 17 pedicels have 11 to 17 lateral papilla?. 

 Number and size of dorsal papilla' is also variable, ranging from 12 (to 

 one ambulacrum) in a 90 mm. individual to 36 in a 120 mm. specimen. 

 In most of the small and medium sized individuals they are very much 

 less numerous and conspicuous than in the iigured (type) specimen. 

 Some of this difference is due to contraction. In the type the papilla? 

 are fully expanded and the anterior and posteriormost arc longest of 

 any. In all but two of the specimens the papilla- appear to be 

 arranged in a fairly regular linear series along each of the two dorsal 

 radii. The exceptions are two small specimens noted in a separate 

 paragraph below. Normal number of tentacles appears to be 20, 

 although they may be as few as 17. The walls are strengthened by 

 spiny tipped rods. (Plate LXXVII, tigs. Ih, 2c, 3//, Sd.) Crown is 

 oblique, subpeltate, with about ten branched divisions ending in small 

 subglobular papilla. The two distalmost branches are much the
