12 THE PROCEEDINGS OF THE LIiNNEAN SOCIETY 



A large tiger-cat has also been seen on more than one occasion, 

 which may possibly turn out to be a new species of the genus 

 Felis, none of which have hitherto been discovered in Australia. 



The scrubs teem with insect life ; large green and golden spotted 

 Butterflies (Ornithoptera cassandra), with the grand blue Papilio 

 ulysses, are among the commonest, On one occasion I obtained 

 over 200 specimens of these beautiful insects before 9 a.m. Two, 

 if not three, species of aligators and crocodiles inhabit the rivers, 

 which makes it particularly interesting to the traveller in crossing; 

 one specimen, however, Orocodilus Johnstoni, named after its dis- 

 coverer Inspector Robert Johnstone, who forwarded the first and 

 still unique specimen to the Australian Museum, is comparatively 

 harmless, and only found in the head waters of the rivers and 

 creeks and mountain streams ; it never inhabits the lagoons, nor 

 has it been observed in the main streams or near the coast. 



Mr. Macleay exhibited a series of specimens of Entozoa and 

 Epizoa taken from a Sunfish captured by Mr. Brazier at Port 

 Stephens on the 28th of November, 1874. 



Mr. Macleay read the following explanatory notes : — 



The small bottle marked No. 1 contains specimens of Bothrio- 

 cephalus microcephalus (Rudolphi). This worm was found m 

 amazing quantity throughout the intestines. I have now in my 

 museum a one-gallon jar of spirits almost full of a nearly solid 

 interwoven mass of these cestodes ; indeed, so tangled and knotted 

 are they, that it took Mr. Masters and myself much time and 

 trouble to separate a few specimens for exhibition. A few small 

 ones we got out perfect, but in no instance were we able to get 

 the larger strobilse in a perfect state. We succeeded, however, 

 in unravelling one nearly perfect which measured over five feet in 

 length, and as there are about sixty proglottides to the inch, the 

 whole strobila must have consisted of nearly 4,000 individuals or 

 segments. The average width of a proglottis is about a quarter of 

 an inch. 



No. 2 bottle contains specimens of Tetrarhynchus reptans 

 (Rudolphi). This is also a cestode worm, but differs from the 

 tape worms generally in its habit of making a tube or sheath, in
