Worm which infests Dogs, but is much more common in the wild 

 species, as the Wolf and Fox, than in the domestic animal. Its 

 History is unknown. 



Mr. Ratte read the following note explanatory of Plate 9, figs. 

 3 to 6, the references to which were accidentally omitted in his 

 Paper on Worthenia. Figs. 3 and 4 Ptychomjjhalus, sp. nat. size. 

 Fig. 5 the same enlarged 2^ times to show sculpture. This Fossil 

 although possessing a round aperture is not a Turbo, and resembles 

 in general appearance Ptychomphalus Frenoyanus, de Kon., from 

 the Carboniferous Limestone of Vise Belgium ; but the sculpture 

 is not the same, the oblique striations visible in the jSgured speci- 

 mens not shov,'ing in Ptych. Frenoyanus. Fig. 6, magnified or 

 enlai'ged three times is another species of Ptychomphalus, with a 

 well-marked sinual band. This specimen is not in the good state 

 of preservation observable in the others. It is found in the lime- 

 stone of Yass, and from the same locality as the supposed Wor- 

 thenia. 



Dr. Cox made some observations on the migrations of the 

 Maray, the fish known as tbe "Australian Pilchard" and " Picton 

 Bloater," Glupea sagax, and called attention to the importance 

 of ascertaining the time and place of spawning.
