for the greater part unilateral. Geuital organs appear in about the 

 one hundredth segment. Male organs: Testicles dorsal, comparatively 

 few in number, 75 to 80 yu 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 O.IG mm. broad; cirrus short, generally lies in two 

 spirals witliin the ixnich; i^rostata 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 i)ore half of median held; uterus ventral, appears as 

 an apparent network with dichotomous i)eripheral branches, and tinally 

 forms a sac Avith indistinct partitions or without partitions. Ova 52 to 

 CO //; pyrit'orm body 12 jj broad by 28 /< long. Calcareous bodies 

 appear in segments containing ova, and become numerous in segments 

 in which the egg shells are distinct.

liiehm described this form in 1881 under the following diagnosis: 



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

 abgcsetzt, weun letztcio nicbt zu stark coutrabiert ist. Gescblecbtsitftnungeu ein- 

 facb, ini dritten Viertbeil des Proglottidenrandes gelogen; Glieder trapczformig, 

 etwa eben so lang wie breit. Liinge im ansgestreckten Znstande bis 100 cm., Breite 

 der reitsten Glieder bis zu 8 mm. Wobiitbier: Lepiis cnniviilits. 



Blanchard in 1891 changed the name to cuniculi on grounds of arti- 

 cles 54 to ijo of the International Code, and i)laced the worm in the genus 

 Anoploccpluda. Railliet in 1893 placed the form in the g&wu^ Andrya. 



I have not yet found this species in the United States, but have been 

 fortuimte enough, through the kindness of Geheimrath Leuckart and 

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



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

 details: The anterior end is veiy narrow (0.4 mm.) and segmentation 

 is scar(;ely visible, so that only the head and a portion of the neck have 

 been lost. Segmentation is noticed 0.G4 mm. from the anterior extrem- 

 ity, while 2 mm. from the end the segments are jierfectly 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 dose 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
