BRAZIER : NOTES ON AUSTRALASIAN MOLLUSCA. 75 



Bulllna lineata GrSiy = Aplusi mm scabrum R. B. Watson 

 (non Chemnitz).— Coogee Bay, Sydney, N.S.W. Found 

 in rock pools. This very pretty species was first described 

 by Dr. John Edward Gray, in 1825, in the "Annals of 

 Philosophy," vol. ix., p. 408, as Bulla lineata from New 

 Holland. The authors since Gray quote it as of Wood. 

 The Rev. Robert Boog Watson, in the " Challenger 

 Report," vol. xv, p. 633, calls it Aphistrum scabrum 

 Chemnitz. The latter species is quite distinct from 

 Gray's species in not being spirally banded with red lines. 

 Chemnitz, in his description of Btilla scabra, only mentions 

 longitudinal rose-red lines, and his figure only shows them 

 as such. They only show as such in the figure given in 

 " Wood's Index Test," Hanley's Edition, pi. xviii., fig. 28. 

 The figure and description given in Reeve "Conch. Icon." 

 is not the Bulla scabra of Chemnitz. The figure in 

 "Sowerby's Thes. Conch. Bulla," pi. 120, fig. i, does not 

 represent Chemnitz's species. Mr. A. Adams, the author 

 of the monograph in that work, gives Chemnitz's descrip- 

 tion, but Mr. Sowerby figures something else showing 

 longitudinal and transverse rose-red lines. I have a true 

 Bulla scabra Chemnitz marked in every way mentioned 

 by that author. I obtained it thirty years ago, near Sydney 

 Heads, in twenty fathoms. It is larger than Btilla lineata 

 Gray, and does not show the transverse rose-red markings 

 that are found in Gray's species. I hold that they are two 

 distinct species — Bulla scabra Chemnitz and B. lineata 

 Gray. As Mr. Angas and myself have observed that Btdla 

 lineata has an operculum it should be placed in the genus 

 iVctason = Tornatella ; if not it must be erected into a new 

 genus. 



Alexia meridionalis Brazier. — Port Adelaide, South Aus- 

 tralia. 



Plecotrema typica H. and A. Adams. — Prony Bay, New 

 Caledonia. This species appears to have a wide range.
