breadth of the sti'obila ( Wolffhiigel. 19»''0h’. Woltfhugel found that 
the two longitudinal muscle layers become more or less fused in the 
older segments so that they can no longer be distinguished as separate. 
Cohn (1901b. p. 320; asserts that the layers in question can not be 
considered indbudually distinct at all. as they nowhere preserve their 
identity for any considerable distance. He also differs with Wolffhu- 
gel in that he failed to ffnd the four isolated bundles described by the 
latter author. Zschokke (1902a. b; has noticed niunerous diagonal 
ffbers connecting here and there the bundles of longitudinal ffbers.

Excuetoey .rTSTEM. — There are two pair- of lateral longitudinal 
excretory vessels, of which the ventral pair are the larger (ffg. 117i. 
According to Wolff'hugel (1900b; tran.^ verse canals connecting the 
longitudinal vessels are lacking, but Cohn (1901b) has found a system 
of small anastomosing canals extending across the posterior portion of 
each segment, connecting the longitudinal canals and taking the place 
of the transverse canals. The excretory vessels and the lateral longi- 
tudinal nerves pass on the ventral side of the cirrus pouch. 
PiEPRODrcTivE SYSTEM. — The reproductive organs lie in the central 
portion of the parenchyma, i. e.. in.-ide of the longitudinal mirscle 
layer, and are so distributed that the female glands occupy the .-inis- 
md third of the proglottis: the three testes and a portion of the 
seminal receptacle the middle third: and the remainder of the seminal 
receptacle, the vagina the seminal vedcle and the 
cirrus pouch, the dextral third (ffgs. 115. 117 1 .
