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 JJL in diameter, and more numerous in the 

 aporose than in the pore side of the segment 5 cirrus pouch 0.32 to 

 0.34 mm. long by 0.16 mm. broad; cirrus short, generally lies in two 

 spirals within the pouch; prostata elongate. 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 // broad by 28 /i long. Calcareous bodies 

 appear in segments containing ova, and become numerous in segments 

 in which the egg shells are distinct.

Eiehm described this form in 1881 under the following diagnosis: 



Kopf hakenlos, klein, aber gegen den sehr diinnen Halstheil stark keulenformig 

 abgesetzt, wenn letztere nicht zu stark coutrahiert ist. Geschlechtsoffnimgen ein- 

 fach, im 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. Wohnthier: Lepus cuniculus. 



Blanchard 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 

 Dr. von Marenzeller, to obtain some of Biehm's original stock. 



One of the specimens, which was mounted whole, shows the following 

 details: The anterior end is very narrow (0.4mm.) 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. Testicles could not be distinguished in
