82 SOME KEW QUEENSLAND ENDOPARASTTES. 



Spiroptera megastoma Kud. 



From a tumour in the stomach of a horse, Eidsvold, 

 Burnett River, collected by Dr. T. L. Bancroft. This 

 species, though probably not uncommon, is apparently 

 now recorded for the first time as occurring in Queensland. 



Agamonema sp. 

 (PI. X., figs. 1, 2.) 

 A small number of white ellipsoid cysts were taken 

 recently from Hyla ccerulea caught in Brisbane (Oct, 1914). 

 They were lying more or less loosely in the wall of the stomach, 

 just below the peritoneum. Each contained a single 

 nematode, jirobablj^ a Spiroptera, lying in its central area, 

 surrounded by a tough fibrous coat, the " worm area " 

 being about half the diameter of the cyst. The largest 

 cyst measured .9 mm by nearly .7 mm and the smallest 

 .65 by .47 mm. 



By teasing out the capsule, the contained worm was 

 liberated. The following account is based upon the largest 

 parasite obtained. 



Length 3.10 mm ; breadth .010 mm. The body is 

 finely annulate, the rings being, however, scarcel}^ recog- 

 nisable anteriorly. The anterior end is rounded and only 

 slightly attenuated while the posterior extremity is pointed, 

 there being a short tail, .010 mm, in front of whose end 

 lies the anus. The three lips each bear a small labial 

 papilla, not readily detected. Delicate longitudinal 

 striae are recognisable on the cuticle of the bod3^ 



There is a relatively long tubular pharynx, .43 mm 

 in length, terminating in a slight swollen portion. The 

 anterior end of the intestine is rounded, a deep constriction 

 separating it from the pharynx. The cloaca extends in- 

 wards for .075 mm from the anus and is lined by a thick 

 cuticle which is so disposed that it has the appearance of 

 two approximately equal spicules with rounded or clublike 

 inner ends separated from each other, and -with sharp outer 

 extremities. It is possible that these may be two male 

 spicules or a single deeply-grooved seta Avith a bifurcate 

 end.
