290 ON SOMIC TRKMATUDK PAKA8ITK8 OF AUSTRALIAN' FROGS, 



Trematodes obtained— from the lungs, 2 ( Pneumonoeces ); duo- 

 denum, '2\\( Dolichosaccus ); rectum, \0( Diplodiscus )\ bladder, 23 

 (Gorgodera). In addition, nematodes were found, a number of 

 times, in the lungs, intestine and rectum. 



Limnodyna><tfs dorscdin. — Out of the 32 specimens examined, 

 trematodes were met with only once, one frog yielding two speci- 

 mens of Dolicliosaccus, which occurred in the anterior part of the 

 small intestine. Nematodes, however, were fairly common, being 

 found, a number of times, in the stomach, intestine and rectum. 



Li'mnodynnstei< tasmaniensis. — -In 77 specimens, trematodes 

 were met with only unce, the rectum of one frog containing three 

 specimens of Diphdisciis. Nematodes occurred in the lungs, 

 stomach and rectum. 



Crinid signifevd,.— The 12 specimens examined contained no 

 trematodes, but nematodes were found in the stomach and in- 

 testine. 



Hyperolia marmorata. — Twelve specimens were examined, but 

 neither trematodes nor nematodes were found, though in the 

 intestine of two specimens, three cestodes were discovered, one in 

 one, and two in the other. 



Pseudophryne bihronii. — The ten specimens examined yielded 

 no entozoa at all. 



Hyla coeridea, — The 49 specimens examined yielded in all 104 

 trematodes. In the duodenum of one frog wei'e i( Mesocieliuni); 

 in another, 92 of the same fluke; in another frog were 7 speci- 

 mens of Dolichosaccus in the anterior part of the intestine, whilst 

 in the rectum of two other frogs were three specimens of Brachy- 

 sacciis. Nematodes were also found in the stomach, intestine 

 and rectum; and cestodes in the rectum. 



I/yla peronii. — Twelve specimens of this species yielded no 

 trematodes, but nematodes were found in the lungs and rectum. 



Hyla phyllochroa. — In the bladders of these frogs, of which 34 

 were examined, 15 specimens of Polydomum were found. Four 

 was the greatest number in one specimen, two was the number 

 most conunonly met, and in several cases, one alone. Nematodes 

 were found in the rectum of two specimens.
