39. Chiton limans, Sykes. 

 \_=muricatus, Ad. non. Tilesius. For synonymy see ante, p. 93.] 



Recorded by Mr. Angas, under the name of Lophyrus muricatus, as 

 having been collected "under stones at low-water, Port Lincoln"; 

 but it does not occur in South Australian collections as a local species. 

 Can Mr. Angas have identified the shell lately described as C. tricostalis 

 by Mr. Pilsbry as C. muricatus, Adams ? 



40. Chiton tulipa, Quoy & Gaim. 



Chiton tulipa, Quoy & Gaim. : Voy. Astrolabe, Zool. iii (1834), p. 389, 

 figs. 35, 36 ; Pilsbry, Man. Conch., ser. I, vol. xiv, 

 p. 185, pi. xxxi, figs. 43-9. 



Lophjrus tulipa, Quoy: Angas, Proc. Zool. Soc. 1865, p. 186. 



Hal. — "Under stones, low- water, Port Lincoln" (Angas). This 

 South African species is not known to have been obtained subsequently, 

 and Angas' identification may be regarded as probably incorrect. 



41. AcANTHOCHiTES Zelandictjs (Quoy & Gaim.). 



Chiton Zelandicus, Quoy & Gaim. : Voy. Astrolabe, iii, p. 400, t. Ixxiii, 



figs. 5-8; Reeve, Conch. Icon., sp. 58. 

 Acanthochmtes Hooheri, Gray : Dieffenbach's " Travels in I^ew 



Zealand," vol. ii, p. 262. 

 Acanthochites Zealandicns, Hutton : Manual N.Z. Moll., p. 117; 



Pilsbry, Man. Couch., ser. I, vol. xv, p. 16, pi. xiv, 



figs. 9, 10. 



It is exceedingly doubtful whether this species is an inhabitant 

 of South Australian waters. 



42. AcANTHOCHiTES scuTiGER (Ad. & Reove). 



Chiton scutiger, Ad. «& Reeve : Conch. Icon., sp. 178. 

 Acanthochites scutiger, Pilsbry: Man, Conch., ser. I, vol. xv, p. 20, 

 pi. ii, figs. 51, 52. 



I do not know this shell, and have not yet had an opportunity 

 of visiting Port Lincoln, the locality from which it is recorded by 

 Mr. J. F. Angas. Its occurrence in Australian waters is discredited 

 by Pilsbry (Proc. Acad. Nat. Sci. Philad. 1894, p. 76). 



43. Ceyptoplax Bueeowi (Smith). 



Chitonellus larvcBformis, Reeve : Conch. Icon., sp. 3. 



Chiton (^Chitonellus) Burrowi, Smith: Zool. Coll. H.M.S. "Alert," 



1884, p. 85. 

 Cryptoplax Burrowi, Haddon : " Challenger," Polyplacophora, p. 42, 



pi. iii, figs. 1 1 a-m. 

 Cryptoplax Burroivi, Pilsbry : Man. Conch., ser. I, vol. xv, p. 54, 



pi. ix, figs. 6-10. 



Hal. — Port Adelaide (Reeve). 



Not known in South Australian collections.
