32 RKCORDS OF THE AUSTRALIAN MUSEUM. 



proglottids it is a simple ring lying in front between the testes 

 and the ovary, laterally just outside of the main mass of the 

 latter gland and frequently between the outer portions of 

 laterally-directed ovarian tubes, and posteriorly, just above the 

 vitellarium on the same dorso-ventral plane as but behind the 

 shell-gland. As development progresses, the uterine wall becomes 

 more or less deeply pouched, especially on its outer side. The 

 cavity becomes filled with a structureless substance which is 

 probably of a mucous nature. A similar occurrence has been 

 noted by Fuhrmann" 8 in the uterus of Gyroccelia leuce. As in 

 the latter species and in G. perversa there is present in the mid- 

 line at the posterior end of each segment a dorso-ventral canal 

 into which the uterus comes to open. Neither this canal nor its 

 rudiment was recognised until sexual maturity had been reached. 

 In G. perversa, Fuhrmann"'' 1 found the rudiment appearing early 

 and was able to trace its development. ISipe eggs were not 

 present in the fragment. 



The known species of the genus G. perversa, G. brevis, G. leuce 

 and G. paradoxa, Linst. 70 , as well as the species under review, 

 are all from birds belonging to the Charadriifoimes and seem to 

 be very similar anatomically, the main difference being in regard 

 to their musculature, the structure of the cirrus and the 

 geographical distribution. 



T^NIA PEDIFORMIS, Krefft. 



There is only a single specimen of this parasite in the Museum 

 collection. It was taken from Anas superciliosa, Gmel. Krefft 

 mentioned Anas punctata, i.e. JVettion caslaneum, Eyton, as 

 another host. Linstow, Wolff hugel and Fuhrmann 7 x have already 

 suggested that this species may be synonymous with Tamia 

 malleus, Goeze, i.e. Fimbriaria fasciolaris, Pall., a statement 

 with which I have agreed 7 -. A further examination of KrefJVs 

 specimen confirms the opinion and consequently his name must
