MARINE SHELLS OF THE CHEVERT EXPEDITION — HEDLEY. 123 



MuREX ADUNCOSPiNOsus, Reeve. 



Murex aduncospinosus, Reeve, Conch. Icon., iii., 1845, Murex, pi. 



xxiii., sp. 93. 

 Murex eximius, Brazier, Proc. Linn. See. N.S. W., i., 1877, p. 



170. 

 The two individuals from Darnley Island are smaller and less 

 thorny than Reeve's figure, but no speciKc differences are apparent. 



Murex conpusus, Brazier. 



(Plate xvi., fig. 4). 

 Murex confusa, Brazier, Proc. Linn, Soc. N.S.VV., i., 1877, p. 172. 



The shell figured is from Darnley Island, and is 27 mm. in 

 length. 



Tritonium angasi, Brazier. 



Tritonium angasi, Brazier, Proc. Linn. Soc. N.S.W., i., 1877, p. 

 174. 

 No specimen of this could be found. 



Marginella l^vigata. Brazier (emend). 



(Plate xvi., fig. 5). 

 Marginella lavigata, Brazier, Proc. Linn. Soc. N.S.W., i., 1877, 



p. 225. 

 ? M. valida, Wsitson, Chall. Rep., Zool., xv., 1886, p. 267, pi. 

 xvi., fig. 3. 

 I am pretty confident that Brazier's shell was redescribed as 

 above. One of the shells from Katow, New Guinea, 5 mm. long, 

 is here figured, A curious feature, not noticed in either descrip- 

 tion, is the dislocation of the parietal teeth ; possibly the 

 "Challenger's" shell, which is smaller, was not old enough to 

 exhibit the character. 



COLUMBELLA CLATHRATA, Brazicr. 



(Plate xvi., fig. 6). 



Columbella clatlirata, Brazier, Proc. Linn. Soc. N.S. W., i., 1877, 

 p. 229, 

 The example drawn is 8 mm. in length, and from Katow, New 

 Guinea. C. brevissima, Hervier,^ seems from the figure to re- 

 semble it. 



Columbella marle, Brazier. 



(Plate xvi., fig. 7). 



Columbella mar ice, Brazier, Proc. Linn. Soc. N.S.W., i., 1877, 

 p. 230. 

 The example drawn is 10 mm. in length, and from Hall Sound, 

 New Guinea.
