THE HELMINTH PARASITES OF MAN. 303 



p. 118 (Sydney), ihid, XXXV., 1910, p. 28 (Queensland), Jour. 

 Proc. Roy. Soc. N.S. Wales, 1909, p. XX. (West Austr.), A.M.G., 

 1909, p. 480 (N.S.W.). In addition to these definite records there 

 are a few others where mention is made of tapeworms, some of them 

 of very considerable length, taken from human beings. They no 

 doubt belong to this species (Flynn, A.M.G., 1901, p. 496— Q'land). 



2. T(Bnia solium Linn., the armed cestode, is practically un- 

 known, the only definite record being that by Johnston (Proc. Linn. 

 Soc. N.S. Wales, xxiv, 1909, p. 118, N.S.W.), but as no history 

 could be obtained it is not improbable that the patient had become 

 infested elsewhere. This suggestion is supported by the fact that 

 the larval or cystic stage, Cysticercus celluloses, which lives in the 

 pig, has only once been reported from the Commonwealth (John- 

 ston, Proc. Linn. Soc. N.S. Wales, 1909, p. 118), and moreover 

 there is doubt as to the correct locality of the specimen. There 

 are two other references to this parasite in man (Iffla, A.M.G., 

 Melbourne, 1869 — Victoria, and Anonymous, N.S. Wales, Med. 

 Gaz. V. 1874-5, p. 57— N.S.W.), but both of these are more likely 

 to refer to T. saginata. 



3. Dibothriocephalus latus L. has once been reported, but very 

 little is known of the history of the case, which was without doubt 

 an imported one (Johnston, Proc. Linn. Soc. N.S. Wales, xxxiv, 

 1909, p. 118 — Sydney). The larva of this parasite is known to 

 infest various European fish 



4. Dibothriocephalus parvus Stephens. This form was obtained 

 by Dr. Elkington from a Syrian in Launceston, Tasmania, and like 

 the last mentioned Bothriocephalid is also an importation from 

 elsewhere. This parasite was considered as a new species by 

 Stephens (Ann. Trop. Med. Parasitol., Feb., 1908). 



5. In addition to the four above mentioned adult species, two 

 larval forms have been recorded, one of them, the hydatid [Echino- 

 coccus veterinorum Rud., E. hominis, Rud., E. polymorphus Dies, 

 etc.), being already briefly referred to. As stated previously, its 

 importance medically is sufficient justification for it to be con- 

 sidered separately in a future communication. 



6. The other is a larval Bothriocephalid, regarded as being 

 identical with that described by Cobbold and Leuckart, and known 

 variously as Spargamtm [Bothriocephalus, Ligula) Mansoni Cob- 

 bold, and B. liguloides Leuckt. We think that the form in question 

 may be similar to the Ligula-like larvae found locally in lizards, 

 snakes and frogs. It is probable that they are not specifically 

 identical with Cobbold's species, but larval Bothriocephalid worms 

 offer few points of specific value. All of these evidently occur only 

 accidentally as human parasites. The one case was reported from 

 Bathurst district, N.S. Wales, by Spencer (Trans. Inter. Med. 

 Congr. Austr. Ill, 1892, p. 433), and the other by MacCormick and
