lowing additional measurements are given: height of head 

 254 mm.; diameter of eye, 60 mm.; height of body at ventral 

 insei'tion, 260 mm.; greatest thickness, 57 mm. The specimen 

 was a fuU-roed female. This great Ribbon-Fish was taken under 

 unique circumstances, from a fisherman's point of view, having 

 been hooked in the locality mentioned, off Banister's Point, 

 while fishing for Snapper, and with a Squid ( Sepioteuthis ) bait. 

 The first recorded example of this species was described in the 

 Society's Proceedings (Vol. v., 1880-1881), and was obtained 

 during 1880, at Manly Beach, where it had been speared. 



Mr. A. R. McCulloch exhibited a male specimen of the 

 Common Water Rat, Hydromys chrysoyaster, var. leucogaster, 

 killed by a dog, in the Botanic Gardens, Sydney. Presented to 

 the Australian Museum by Mr. J. H. Maiden, F.L.S. 



On behalf of Mr. A. B. Walkom, Mr. Dun exhibited specimens 

 of Glendonites from the upper beds of the Lower Marine Series 

 (Permo-Carboniferous) of Harper's Hill, Allandale. 



Dr. E. A. D'Ombrain showed the unidentified hard kernels of 

 the fruits of two North Queensland trees, one growing in the 

 open forest, the other in the scrub, which had been forwarded to 

 him by Mr. W. McLennan, from Cape York, as furnishing part 

 of the dietary of the Great Black Palm Cockatoo {Microglossus 

 aterrimus Gnielin). 



Dr. J. B. Cleland showed Cysticerciis tenuicollis and Echino- 

 coccus veterinorum from sheep, illustrative of the way in which 

 the perpetuation of the species is provided for during the eating 

 of such cysts by dogs. In C. tenuicollis, only one head of a 

 future tapeworm {T. marginata) is found in each cyst. It is of 

 considerable size, and would be easily crushed by the teeth of a 

 dog, if it were not for the fact that the cyst hangs dependent 

 from the liver or abdominal organs of the host. The dog, in 

 eating these, after hasty chewing, swallows part of the organ 

 which, as it descends, draws after it the dependent cyst which 

 had been hanging outside the dog's mouth. In the Echinococcus, 

 numerous scolices, representing immature heads, cover the inside
