The next records of Chama were by Angas, who, in his cata- 

 logue of Port Jackson shells, included C. spinosa Broderip, in 

 1867, and C. reflexa Reeve, in 1871. C. spinosa was described 

 from Lord Hood's Island, or Marutea, in the Paumotus, and its 

 appearance here is improbable. It seems to be based on a shell 

 too young to display specific characters. C. reflexa is from 

 Darnley Island or Erub, Torres Strait. The figure of it does not 

 well agree with the Sydney shell. From Cape York, Smith 

 identified C. jukesii as taken by the " Challenger," and unites to 

 these, as synonyms, C. fibula Reeve, and C. pellis-phoccB Reeve. 

 The two latter are again recorded from this area by Melvill &, 

 Standen. 



Of these three, C. fibula was published in December, 1846, 

 and must, therefoi^e, take precedence over C. jitkesii and C. 

 pellis-yhoccE. "Preliminary" descriptions of the two latter were 

 issued 27th January, 1847, in the Proceedings of the Zoological 

 Society, but perhaps subsequent to their appearance in the 

 Iconica in January, 1847. 



In the case of another Queensland species, Chama pulcheJla, 

 Reeve seems to have intruded not only on the prior C. lohata 

 Broderip, and the Lamarckian C . damcecornis, but on the original 

 Linnean Chama lazarus. 



There is yet another species described by Reeve as C . nivalis, 

 which Jukes procured in Queensland, and which seems to me 

 likely to be preoccupied by Lamarck's Chama limhula.* 



Such items as these support Cooke's contention that, in Chama, 

 " Reeve has made fifty-five species out of material probably 

 better represented by ten."t

(Plate li., figs.38, 39.) 

 Shell rather thin, inflated, truncate-circular. Colour dull 

 white. The lunule-side is straight, cutting off a segment from 

 the circle which the margin of the valve otherwise describes.
