TWO NEW SPECIES OP ONYCHOPHOHA. 533 



Fig. 6. — Lateral view of one of the legs of Eoperipatus Weldoiii. 

 Note the two distal papillae situated on the distal mai^in, one in front and 

 one behind. Each of these papillEe is divided into a basal and an apical i)iece, 

 the latter of whicii carries a spine. Also note the ventral prominences or 

 ridges which have the appearance of two recumbent papillfe pressed against 

 the latero-ventral aspect of the foot. Every prominence carries a spine 

 similar to the one on the distal papillae. 



Fig. 7. — A. primary papilla from the dorsal surface of Eoperipatus 

 Weldoni. Note the conical basal part. 



Fig. 8. — A primary papilla from the dorsal aspect of the leg shown in 

 l''ig. 6. Note the cylindrical basal part, and compare with tiie conical basal 

 part of the papilla shown in F'ig. 7. Intermediate stages between the papillae 

 represented in Figs. 7 and 8 are very common. 



Fig. 9. — A ventral view of the fourth and (ifth legs ol Eoperipatus 

 Weldoni. Note the position of the renal papilla, ou the top of which the 

 renal pore is situated. Note that by its position it divides the pad into two 

 pieces. 



Fig. 10. — This figure represents a portion of the skin of the dorsal surface 

 of Eoperipatus Weldoni. Note that the primary papilla; [p.p.) have a 

 polygonal or perfectly irregular outline, and that they stretch across the 

 ridges from one groove to the other. The grooves between the ridges are 

 exceedingly narrow, and the accessory papilla; are often situated in the 

 grooves as well as on the ridges. The accessory papilla; are very numerous, 

 and their outlines are quite distinct. At the lower left-hand corner of the 

 figure there is no special arrangement of the ])apillse, tiiougli the position in 

 question is situated above the leg. The position marked m. d. I. represents 

 the mid-dorsal line. 



Fig. 11. — The inner [Wo) and the outer {\lb) blades of the jaws of 

 Eoperipatus Weldoni. Note that there are two denticles on the inner 

 side of the large tooth in each blade. The inner blade has a diastema, fol- 

 lowed by a number of smaller denticles. 



PLATE 34. 



Fig. 12. — The inner (12«) and the outer (126) blades of the jaws of Eo- 

 peripatus Horsti. Note that they have almost the same characters as 

 those figured on the [)revious plate, though they are different in size. 



Fig. 13. — This figure represents a portion of the skin of the dorsal surface 

 of Eoperipatus Horsti, and should be compared witli Fig. 10 on the 

 previous plate. Note the well-defined transverse ridges and grooves. The 

 primary papillse have not the sharp, irregularly shaped outline found in
