Body flattened leaf-like twice as long as broad or less widest in the anterior body half ; one side nearly straight and the other strongly convex giving the appearance of two curved sides meeting at the widest part of the body ; anterior end rounded and in the same line with the straight side ; posterior end tapering and rounded ; numerous nuclei. [...] The reaction becomes possible by the fact that benzophenone has a great tendency for the fomation of ring compounds the hydrogens of the para-positions of the phenyl groups taking part in the reaction. [...] He further appended a table noting the differences in the character of the dorsal membranelles zone " and in the number of the " vacuoles." Thus in Ophryoscolex Stein the " dorsal membranelles zone " is an incomplete spiral encircling 5 of the entire body and the vacuoles are 5-6 in number. [...] The present paper aims at arranging the genera and species of the Ophryoscolecidae according to the latest researches and describing a number of new forms from the rumen of the cow and goat. [...] The present species differs mainly from E. bursa Stein in general shape of the body in the absence of a posterior depression and in the shape of the macronucleus.
