Blanchard. Geographical distribution.—Maryland (by Hassall), Florida (by Mills), Long Island (by Peters), ? Puget Sound (collection of Leidy). Varieties.—To classify the forms at my disposal, I am compelled to recognize three varieties: (a) G. variabilis. B. A. I. Cestode series No. 117, type of the species is designated as type of this variety. The posterior flaps of the seg- ments are nearly straight; genital pore in about the middle of the lat- eral margiu. Habitat: Lepus sylvaticus. (b) G. variabilis angusta. B. A. I. Cestode series No. 1119, designated as type and deposited in the United States National Museum. This variety is only about 2 mm. broad, the posterior flap is straight and does not overlap prominently, the genital pore is generally in the posterior half of the lateral margin. Pores occasionally single. (c) G. variabilis imbricata. No. 1246, U.S.N.M., borrowed by B. A. I.; B. A. I. Cestode series No. 1246, designated as type and returned to United States National Museum. At first sight it seems almost like splitting hairs to create a variety for these specimens the technique of which was different from that of G. variabilis. The worms were col- lected by Robert Mills, an enthusiastic collector at Chuluota, Florida, and kindly presented to the United States National Museum. They were placed in 95 per cent alcohol, accordingly they are somewhat con- tracted. The posterior border of the segments is lobed, a character which is quite constant, and overlaps the next following segment about one-third of its length so that the segments have a general campulate appearance.

In order to meet objection to this ruling, should objection arise, I here definitely pro* pose Tcenia malleus, Goeze, as type of the subgenus. Proc. N.
