a part in altering the size of the head, thus supporting the view, 

 as to the function of the " ballonets," recently put forward in a 

 paper read before this Society by Baylis and Lane*. 



A microscopical examination of tlie faeces of the same Leopard 

 Cat showed many minute ISTematode embryos. A similar exami- 

 nation of the stomach contents gave the same result, but no 

 adults could be found in this or any other of the neighbouring- 

 organs. However, in tlie mucosa of the oesophagus and naso- 

 pharynx the same embryos were present, but liere each was 

 coiled up in an exceedingly thin membranous shell. The pre- 

 sence of these viviparous eggs in the nasopharynx led to the 

 discovery of the adult worms in a most unusual position, for the 

 frontal sinus was next explored, and here large numbers of a 

 species of Synthetocaidus were found. So far as Ave have been 

 able to ascertain, this species is new to science, but it is closely 

 allied to S: riifescens, which occurs occasionally in the lungs and 

 air-passages of the Sheep in Europe. 



It is of interest to note that for some time before death the 

 animal suffered ivom "fits'" and was often seen to lose its balance 

 and fall. These " fits," and loss of equililnium were no doubt 

 due to the presence of Synthetocaidus in the frontal sinus. 



Further examination of the fteces from the same animal 

 showed many Trematode ova, wliich weie i-ecognized as those of 

 Parcujonliiias loesteniianni. The lungs were then searclied, and 

 four specimens of the adult fluke found. The number of eggs in 

 the faeces Avas exceedingly large considering the few adults which 

 gave rise to them. 



1 am indebted to Professor II. T. Leiper for his invaluable 

 assistance and advice on a number of the more intricate points 

 arising in the course of the above inquiry.
