AUSTRALIAN POLYPLACOPHORA — HEDLEY AND HULL. 265 



LlOLOPHURA CURTISIANA, Smith. 



Chiton (Ischnochiton) curlisianus, Smith, Zool. Coll. Alert, 

 1884, p. 78, pi. vi., f. d. 



Lioloj)hura curtisiana, Pilsbry, Man. Conch., xiv., 1892, p. 2-42, 

 pi. xxiv., f. 6. 



Enoplochiton torri, Bastow & Gatliff, Proc. Roy. Soc. Vict., 

 xx., 1907. p. 27, pi. iii , iv. 



This shell is common near Gladstone, where Dr. Torr, JMr. T. 

 Iredale, and one of us have gathered it. Messrs. Bastow and 

 Gatliff appear to have overlooked the original description and to 

 have redescribed it as above. 



ACANTHOCHITES MAUGHANI, Torr <k Ashhy. 



(Plate lxxiv., fig. 24-27). 



Acaiithochites maughani, Torr ck Ashby, Trans. Roy. Soc. 

 S. Austr., xxii., 1898, p. 218, pi. vii., f. 5. 



This species, new to our coast, was taken by one of us ( A.F.B. H. ) 

 at the Bottle and Glass Reef, and at Freshwater Bay, near 

 Manly. 



ACANTHOCHITES WILSONI, Si/keS. 



Acanthochites ( Notoplax ) ivilsoni, Sykes, Proc. Malacol. Soc, 

 ii., 1896, p. 92, pi. vi., f. 2. 



This species is rarer here than in the south, two specimens 

 from Long Reef, near Narrabeen, being all that have been found. 

 Except in size these correspond well to examples from St. Vincent 

 Gulf, South Australia, collected and kindly forwarded by 

 Dr. W. G. Torr. One N. S. Wales individual measured when dry 

 19 - 5xll mm. Pilsbry's remark, quoted by Sykes, notes that " tufts 

 seem quite absent." When alive the girdle of our specimens was 

 very wide and fleshy, dark purple in colour, with small sutuial 

 tufts which disappeared in drying. From this we are unable to 

 distinguish A. verconis, Torr and Ashby. 4 



Acanthochites carinatus, Adams & Angas. 



Acanthochites carinatus, Pilsbry, Man. Conch., xv., 1903, p. 17. 



Mr. E. A. Smith regards this as identical with the European 

 A. discrepans, while Dr. Pilsbry hints that a closer scrutiny may
