374 I- IJIMA AND T. KURIMOTO. 



We did not see the entire specimen, Init sam])le pieces from four 

 different regions of the bod}^ were kindly placed at our disposal. 

 They were preserved in strong spirit that liardened tliem into stiffness 

 but kept the tissues in excellent condition. 



Sample No. 1 is a piece from near tlie anterior end of the original 

 specimen. It measures 3 mm. in breadth and 0.5 mm. in thickness 

 at the middle. No trace of reproductive organs is visible in tliese 

 seo'ments.

iSam[)le No. 2 is a piece somewhere from the anterior quarter of 

 the (original specimen. At this region the 1)ody already presents con- 

 sidernljJe dimensions, being 18 mm. broad and about 1.5 mm. thick. 

 Tlie reproductive organs are partly developed ; l)ut of this, later on. 



Sample No. o is from the middle ]3ortion, 14-16 mm. broad and 

 about 1.5 mm. thick. The reproductive organs are fully developed 

 and the uterus is already partially filled with eggs. 



Sample No. 4 consists of two pieces from the posterior p(jrti<3n, 

 one of them cut off' -10 cm. from the hind end. Breadth varies 

 from 10 mm. to 15 mm ; thickness measures 1.5 mm. or some- 

 what more. The varying breadth is certalnl\- due to different states 

 of contraction and accordingly, where the brcadtli is less, the proglottis 

 is comparatively longer. The uteri in this section are nuich distended 

 and tilled u]j with eggs. 



Mr. Nakamura's measurement of maximum lireadth, rjamely :25 

 mm., was no doubt taken whem the worm was (piite fresh. This 

 accounts for the fact that nowhere in the alcoholised and contracted 

 saiu{)les before us is that great Ijreadth attained. Tlie foremost 

 portion of the original specimen, stated by Nakamura to \\ii\e been only 

 1.5 mm. broad, must have belonsfed to a section more anteriorlv 

 situated than our sample No. 1.
