Show 610 DR. J. MURIE ON A N E W TAPEWORM. [June 23, When more complete specimens are obtained, tbe characters, new species, may he better defined ; but provisionally, until more is known, I propose to designate it Tcenia magna, on account of its immense size or, rather, breadth. Fig. 1. A to F. Segments of Tcenia magna ? G. Serrate overlapping margin. H. Interior structure of a layer from a large joint. All about natural size. TAENIA MAGNA, Sp. n. 1 Segments of body pale-coloured, unequal in size, and large; flat, relatively thick, broader than long, and transversely ribbed or banded. The larger segments measure fully 1| inch broad and 1 inch long; 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 parallelo-piped, but the larger chiefly subquadrate. The free borders of the bands are wavy, at some points verging towards subcrenation. Here and there a band presents a partial fold on 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. Body supposed to increase from before backwards to middle, or beyond, and thence to diminish. Habitat. Intestines of Rhinoceros (R. indicus). Specimens deposited in the British Museum. |
