I'AIIASITIC WORMS LEIPER AND ATKINSON. "> 



in />. in-fl'iiliiifiini. Thev were found bv Mr. 1 1. (i. Lillie, in a seal killed near ( 'oiilman 

 Island. Lat. 74 S. approximately, and a similar set was seen at lint 1'oint in 

 Lat. 77 45' S. 



/-.'.i-ti'i-iiii/ A/'/" iinn/'-i'. The worms are from :i cm. to <> cm. long, the average 

 length being about f> cm. The strobila is shaped like an Indian club, being narrow in 

 front, broadest behind the middle, and tapering slightly to the hinder end. The colour 

 is a vellowish white. The head, around the suckers, contains a very characteristic 

 scarlet pigment. 



II, 'nl. -The head measures I Mi I mm. from before backwards, and l'44 mm. from 

 side to side in its broadest part. Anteriorly there are two deep suckers lying ventrally 

 and dorsallv. The sucker measures ()'.V2 mm. internally. 1 mm. externally, and 

 1 -4f> mm. from before backwards. Its hinder part is surrounded by a free edge. A 

 bright scarlet pigment-band on the outer side of the fold surrounding the sucker is 

 verv characteristic. It onlv encroaches partially on the inner side and measures 

 () I 1 mm. at its broadest part. 



S,-i/iin-/if.<<. The segments immediately succeed the head without the interposition 

 of a neck. Thev vary in size, measuring 2 mm. transversely at the head-end, 5 mm. 

 at the broadest portion, and :! mm. at the tail-end. The segment described is from 

 near the head-end of the worm. The dorso-veutral measurement is 2'14 mm. The 

 segment consists of a central portion, measuring 0".>2 mm. from before backwards, 

 and two lateral portions. There is marked imbrication of the segments, as in 

 />. / a rt'i'/infiiiH. The genital openings are central and are placed partly on the anterior 

 surface of the overlapping edge. The cirrus is fairly large, measuring 0'41 mm. in 

 length and O'llmm. in breadth : it is anterior to the vagina, which is a slender tube 

 measuring 0'24 mm. in length and 0'02 mm. in width. The testes are numerous and 

 extend out into the lateral portions of the segment. The uterus is also extensive, the 

 eggs, which measure 0'025mm., being present in the later segments to near the 

 peripherv. Two winding excretory canals run down either side of the segment close 

 to the junction of the central and lateral portions. The musculature is not so well 

 marked as in />. perfoliatum. The longitudinal bands are small and are not continuous 

 over a large number of segments. The fibres are small and insignificant. The circular 

 libres are better marked. 



2f>. Plerocercoid In mi. sp. inc. (1M. V. tigs. :;'.). 42.) 



A lew larvae, apparently of Bothriocephalid Tapeworms, were found encysted 

 under the mucous coat ol the pyloric processes of the gut of Trematomus beiitncc/iii. 



It is impossible to associate them with any particular species, but there is everv 

 probability that they are the young stages of one or other of the species of I >iln>tliri- 

 <-i /i/Kt/itx or DipliyUobothriwm found in the Seals.
