2. Dibothriocephalus cordatus (R. Leuck.), 1863. 

 Syn. : Bothriocephalus cordatus, R. Leuck. 



Length, 80 115 cm. ; the head is heart-shaped and measures 

 2 mm. by 2 mm. The suctorial grooves are on the flat surface ; 

 the segments commence close behind the head and increase rapidly 



in breadth. At only 3 cm. behind the head 

 they are already adult ; the greatest breadth 

 attained by them averages 7 8 mm., the 

 length 3 4 mm. ; the number of proglot- 

 tides averages 600 ; the most posterior ones 

 are usually square. The rosette of the uterus 

 is generally formed of six to eight lateral 

 loops- The eggs are provided with lids and 

 datus ; on the left viewed measure 0*075 mm. in length by 0*05 mm. 



sideways, on the right . -, ,,-, 



from the dorsal surface. m Dreadtn. 



(After Leuckart.) Dibothriocephalus cordatus is a common 



parasite of the seal, the walrus and the 



dog in Greenland and Iceland, occasionally of man also. No 

 doubt its larva lives in fishes. 1 



The statement that Dib. cordatus also occurs in Dorpat in human beings 

 has been proved erroneous (Zool. Anzg., 1882, v., p. 46), as also has the 

 report that this worm lives in hares in the neighbourhood of Berlin,
