534 RICHAKD EVANS. 



Eoperipatus Weldnni. The accessory papillEe, wliicli are here much less 

 numerous, and arc scarcely ever found in the grooves, lose their individuality 

 ill that of the transverse ridges which rise u|) suddenly from the genera! sur- 

 face. The middle of the hack is occupied by a clear narrow line. At the 

 lower right-hand corner of the (igure is represented the special arrangement 

 of ridges and grooves which exists in relation to the leg. This should be 

 compared with the lack of arrangenient in the lower left-hand corner of 

 i\g. 10. 



fiG. 14. — Ventral view of the anterior end of Eoperipatus Horsti. 



Fig. 15. — Ventral view of the |)Osterior end of Eoperipatus Horsti 

 (feniale). 



EiG. 16. — Ventral view of the })osterior end of Eoperipatus Horsti 

 (male). 



Fig. 17. — This figure represents an antero-ventral view of one of the feet 

 of Eo|)eripatus Horsti. Note the two distal papillse and the four ventral 

 prominences or ridges. The two distal papiihe, as in E. Weldoni, are divided 

 into basal and apical portions, and carry a spine. The ventral prominences 

 also carry a spine. 



Fig. 18. — Postero-dorsal view of the same foot, as shown in Fig. 17. 



Fig. 19. — A primary papilla from the dorsal surface of Eoperipatus 

 Horsti, 



Fig. 20. — A primary papilla from the dorsal aspect of one of the legs of 

 Eoperipatus Horsti. Note the same difference between the basal |)or- 

 tious of the papillae shown in Figs. 19 and 20, as was noticed between those 

 represenied in Figs. 7 and 8. 



Fig. 21. — Ventral view of the fourth and fifth legs of Eoperipatus 

 Horsti. Note the position of the jiapillse wliicli carry the renal openings 

 as compared with that which occurs in Fig. 9. 



Figs. 22 and 23.— These figures reiiresent two dissected females of Eo- 

 peripatus Weldoni. Note the difference in the arrangement of the uteri 

 in the two figures. In Fig. 22 the uteri, full of embryos, are packed near the 

 posterior end, under the loop of the intestiual canal, while in Fig. 23 they are 

 arranged on the right side, and extend forward as far as the first pair of legs. 



PLATE 35. 



Fig. 2'±.— The renal organ of the second pair of legs of Koperipatus 

 Horsti. Tlierc is neither a terminal bladder nor a differentiated funnel. The 

 coelomic end-sac is well developed. 



Fig. 25. — The renal organ of the fouith pair of legs of Eoperipatus 

 Horsti. There is no terminal bladder, but the funnel is well developed. The 

 renal duct, as a whole, is very long and coiled.
