INTRODUCTION 



During the .spring of 1915 while studying the eiliatas from the 

 caecum of the horse I became particularly interested in one of a rather 

 bizarre shape. Upon consulting the literature on this subject I found 

 that Fiorentini (1890) and Bundle (1895) had described certain forms 

 apparently closely allied to the one in question. But on more detailed 

 investigation I noticed differences of such a nature as to convince me 

 that I wa.s dealing here with a form not described by either of the 

 above mentioned authors or by others. 



The aim of the present paper is to give the general morphology 

 of this form and to compare it with the closely allied forms described 

 by Fiorentini (1890) and Bundle (1895).
