![VOL. XIX. TAPEWORMS OF HARES AND RABBITS—STILES. for the greater part unilateral. Genital organs appear in about the one-hundredth segment. Male organs: Testicles dorsal, comparatively few in number, 75 to 80 pi in diameter, and more numerous in the aporose than in the pore side of the segment; cirrus pouch 0.32 to 0.34 mm. long by 0.10 mm. broad,- cirrus short, generally lies in two spirals within the pouch; prostata elougate. Female organs: Vagina slightly distal of cirrus pouch, swells to a large receptaculum seminis median and dorsal of ventral canal; ovary, shell-gland, and vitellogene gland distal in pore half of median field; uterus ventral, appears as an apparent network with dichotomous peripheral branches, and finally forms a sac with indistinct partitions or without partitions. Ova 52 to 60 pyriform body 12 p broad by 28 M long. Calcareous bodies appear in segments containing ova, and become numerous in segments in which the egg shells are distinct. Most.

Eiehm described this form in 1881 under the following diagnosis: Kopf hakenlos, klein, aber gegen den sehr diinnen Halstheil stark keulenformig abgesetzt, wenn letztere nicbt zu stark contrakiert ist. Gescklechtsoffnungen ein- fach, lm dritten Viertheil des Proglottidenrandes gelegen; Glieder trapezformig, etwa eben so lang wie breit. Lange im ausgestreckten Zustande bis 100 cm., Breite der reifsteu Glieder bis zu 8 mm. Wohiithier: Lepus cuniculus. Llanchard in 1891 changed the name to cuniculi on grounds of arti- cles 54 to 55 of the International Code, and placed the worm in the genus Anoplocephala. Eailliet in 1893 placed the form in the genus Andrya. I have not yet found this species in the United States, but have been fortunate enough, through the kindness of Geheimrath Leuckart and Hr. von Marenzeller, to obtain some of EieknPs original stock. One of the specimens, which was mounted whole, shows the following details: The anterior end is very narrow (0.4 mm.) and segmentation is scarcely visible, so that only the head and a portion of the neck have been lost. Segmentation is noticed 0.64 mm. from the anterior extrem- ity, while 2 mm. from the end the segments are perfectly distinct, meas- uring 0.8 mm. broad by 0.24 mm. long. The anlagen of the female organs are indistinctly visible at about this point; they lie close to the pore side of the segment, but owing to the poor condition of the mate- rial they can not be analyzed.
