210 NOTES ON MISCELLANEOUS ENDOPARASITES. 



Since Dr. Dodd's remarks would seem to imply that 

 the parasite occurs in N.S.W., I wrote asking for further 

 information. In reply he stated that he had not personally 

 met with a case of Gid in that State, but had been informed 

 that it had been seen there and occasionally in Melbourne. 

 He went on to say, though proof is necessary before the 

 statement can be accepted cis couclusive, that he is not 

 prepared to state that Gid does not exist in N.S.W., because 

 the causal parasite has not been demonstrated. He 

 mentioned that he had examined large ninnbers of sheep 

 all over that State without having encountered a case. In 

 a later letter he agreed that it was quite possible that persons 

 had confused other conditions and Gid, and believed that 

 some of the cases mistaken for gid were probably due to the 

 presence of Echinococcus hydatids in the cranial cavity. 



In view of the evidence given by Dr. Dodd, as well as 

 that which I have collected, we cannot at present affirm the 

 occurrence of Multiceps multiceps in Australia. It must 

 be struck off the list of entozoa actually known as occurring 

 in this continent.* 



Tcenia hydatigena Pall. 

 The occasional presence of the bladder worm stage 

 {Cysticercus tenuicollis) in pigs in south-eastern Queensland 

 is now noted for the first time. 



*In the same paper (p. 508) Dr. Dodd refers to the presence of 

 Trichostrongylus axei {Slrongylus gracilis) and other stomach worms in 

 Australian sheep and cattle. (See also Dodd, Ann. Rep. Dept. Agric. Q'land, 

 1909, p. 9.3-4, where he calls it Sir. gracilis). Cobbold (Parasites, etc.. 1879, 

 p. 283) gave the name Stroiigylus axei to certain minute nematodes occurr- 

 ing in the mucous membrane of the stomach of donkeys. Railliet and 

 Henry (C. R. Soc. Biol, 66, 1909, p. 87) placed S. gracilis McFad. and S. 

 extenuatus Raill. as synonyms of Tricho. axei Cobbold. Ransom in his 

 fine account of the nematodes occurring in the alimentary tract of sheep, 

 cattle, etc. (Bull. 127, U.S. Dept. Agric, B.A.I. , 1911, p. 94) referred t<y 

 S. gracilis McF. as a synonym of Railliet's Tricho. extenuatus, making no 

 mention of Tr. axei as a parasite of stock — apparently not accepting 

 Railliet's views. Leiper ( Jour. London Sch. Trop. Med., 1 (1), 1911, p. 25) 

 in his check hst, mentioned Tr. axei as a parasite of Equidaj and (I.e. 1 

 (2), 1912, p. 116) queried its presence in cattle. In my census of Queens- 

 land endoparasites (1916) I referred to Dodd's record of Sir. gracilis as 

 Tr. extenuatus Raill, following Ransom (1911) rather than Railliet (1909). 

 Tn view of these remarks Tr. axei cannot yet be added to our known hel- 

 minth fauna unless it be admitted that the two names Str. axei Cobbold 

 and S. gracilis McFadyean (not Leuckt are synonymous.
