NOTES AND EXHIHITS, 



{Before the Royal Society of Queensland, August I4th, 



1914). 



Endoparasites (Trematoda). 



Dr. T. Harvey Johnston exhibited specimens of a 

 trematode, Dolichosaccus ischyrus, J. S. Jnstn, which he 

 had collected from the intestine of the common green frog, 

 Hyla ccerulea, in the Brisbane district. This species was 

 described by Dr. S. J. Johnston (Proc. Linn. Soc, N.S. 

 Wales. 36. 1912, p. 313, pi. 17), whose material was obtained 

 from the same species of frog as well as from another in 

 the neighbourhood of Sydney, N.S. Wales. The parasite 

 is here recorded for the first time as occurring in Queensland. 



He also exhibited specimens of a large trematode taken 

 by Mr. A. C. Bligh, from the swim-bladder of a fresh-water 

 catfish (Siluroid), Cojndoglanis tandanus, caught in the 

 Gondamine River, near Warwick, Queensland. These 

 parasites, which Were obtained in February, 1911, through 

 the kindness of the Government Entomologist, Mr. Henry 

 Tryon. have proved to be a species of Isopurorchis. This 

 genus was recently established by Southwell (Rec. Indian 

 Museum V) (2), 1913, pp. 91-95), for the reception of a 

 species, /. trisimilitubi'^ , Southwell, which was taken from 

 the air-bladder of a fresh-water siluroid, Wallago attu, at 

 Bankipur, in Northern India. It is of interest to find ver\- 

 closely related species of this genus occurring in freshwater 

 catfish in two such widely-separated localities as India and 

 Queensland. A full description of the Queensland species 

 will be published by Dr. S. J. Johnston, of the Sydney 

 Universitv.
