which he collected in North Western Austraha, and I have had 

 an opportunity of inspecting Krefft's collection also. The 

 latter is very indifferently preserved.

p. 682. (X.W. West Austraha.) 

 d Physaloptera sp., Krefft, 1871, p. 214. 

 I have a few specimens collected by Dr. Cleland. 

 e Echinorhynchus sp., Krefft, 1871, p. 214. 

 I have some immature echinorhynchus from the sub- 

 peritoneal tissues (Johnston, 1910 d, p. 659) collected by 

 Dr. Cleland. 



/ Porocephalus sp., Krefft (1871, p. 214) recorded the 

 presence of Pentastomum in the lung of the above 

 snake. 'His specimens are specifically identical 

 A\dth those which I have received (Johnston, 1910 

 d, p. 28) from Dr. Cleland. For the present they 

 may be provisionally identified as Porocephalus 

 teretiuscidus (Baird), which they very closely 

 resemble.

Bennett in his book " Wanderings in Kew South Wales, 

 1834," Vol. I., p. 215, refers to the presence of bright red 

 worms one and a-half to two inches long, affecting the lung 

 and perforating the stomach wall of the brown snake. The 

 lung worm is possibly Porocephalus teretiusculus. The 

 stomach worm may have been a Diaphanocephalus or other 

 Strongyle.
