On the structure of Taenia gigantea (Peters). 381 



Taenia magna n. sp. — Segments of body pale colored, unequal 

 in size and large, Hat, relatively thick, broader tlian long and trans- 

 versely ribbed or banded. Tlie larger Segments measure fnlly 

 IV2 inches broad and 1 incli in length. The smaller Segments have 

 a diameter of an inch lengthwise and across. The latter with 

 lateral convex margins and concave attached surfaces. Other pieces 

 are cubical in outline some parallelopiped but the larger chiefly 

 subqnadrate. The free borders of the bands are wavy, at some 

 points verging toward subcrenation. Here and there a band presents 

 a partial fold upon itself; the outer recurved margins of the one 

 band partially overlap that behind giving a somewhat lateral serrate 

 character to each segment. Genital outlet apparently on each band 

 and opening at the lateral border (?). Head and neck not known.

*§■ ' ■ portion of tbe specimen. The margins of the segments 



are smooth. The genital pores are seen to the right. 



Body supposed to increase from before back ward to the middle or 

 beyond and thence to diminish. Habitat: Intestine, Rhinoceros 

 indicus. 



Petees comments upon this note of Murie in the next volume 

 of this same Journal (in: Proc. zool. Soc. London, 1871). He repeats 

 his diagnosis as quoted above and adds that to distinguish this form 

 from Taenia lata he woiild propose the name Flagiotaenia gigantea. 

 He gives a sketch of the head of the worm as he had seen it and 

 this we have copied and reproduce herevvith (Fig. A). He comments 

 upon the obvious error of Mueie in saying that the segments are 

 1 inch long, for as he says, the greatest length of each segment 

 is ^8 inch. 



It seems that we are dealing with the same worm which 

 Petees and Mueie studied and which they, too, agreed to be one
