PLATE 13. 



The figure on this plate represents one of the biggest of the female 

 specimens. It measured about 80 mm. in length when in motion. 



PLATE 14. 



Fig. 1. — This figure represents a portion of the skin situated on either side 

 of the clear line which occupies the mid-dorsal position. The large primary 

 papillae [p.p.] alternate with tiie almost equally large secondary papillae {s.p.). 

 The apical piece of the primary papillae is not represented. Note the tracheal 

 openings situated on either side of the clear line and between the folds of the 

 skin. 



Fig. 2. — This figure represents a portion of Ihe skin from a position close 

 to one of the appendages. The primary papillae [p.p.] lack the sharp basal 

 outline of those shown in the first figure, and the secondary papillae {s. p.) are 

 far more numerous and smaller than those shown in the first figure, a result 

 brought about probably by the breaking up of the latter. 



Fig. 3. — This figure illustrates the inner blade of the jaw. 



Fig. 4. — This figure illustrates the outer blade of the jaw. 



Fig. 5. — This figure represents the fourth leg of the left side. Note the 

 position of the renal papilla between the third and fourth spinous pads, and 

 that it is quite clear of both of them. 



Fig. 6. — This figure represents the twenty-second walking appendage on 

 the right side of the male type specimen. Note the two large sexual papillae 

 situated on the postero-ventral aspect of the proximal end. 



The fifth and sixth figures should be compared, because they incidentally
