 Sculpture consisting of concentric somewhat irregular plications and 

 fine striae, crossed by microscopic radial lines. Epidermis yellowish- 

 brown, easily lost. Colour purple at the umbones, a few purplish- 

 brown concentric bands, two whitish radial rays posteriorly, separated 

 by a brown streak. Interior with a white callosity between the ad- 

 ductor-scars and at the posterior end. Margins sharp. Hinge rather 

 short, with strong nymphs, right valve with 2 divergent cardinals, 

 left valve with 2 cardinals, the anterior bifurcate, the posterior a

Length, 57 mm. ; height, 35 mm. ; diameter, 14 mm. 



Hob. One specimen was found in Manukau Harbour by Mr. 

 Albert E. Brookes, Auckland. Australia and Tasmania. 



Remarks. The shell was kindly identified by Mr. Edgar A. Smith, 

 I.S.O., of the British Museum, who also informed me that S. incerta, 

 Reeve, is in his opinion most likely a Western Australian species, and 

 the New Zealand habitat of the Conch. Icon, may be a mistake. 



Trivia australis. Page 302. 



Since writing the remarks on Trivia zealandica, T. W. Kirk, I have 

 had an opportunity of seeing the type specimen, and found it to be 

 a good species, distinct from T. australis. 



Phalium labiatum, Perry. Page 312. 



The specific name labiatum is preoccupied by Chemnitz, and 

 Lamarck's name achatinum should be used (A.s.V., vii, 1822, 226 ; 

 A.s.V., 2nd ed., x, 1844, 33). 



Mitromorpha striata, Hutton. Page 488. 



Having now examined a series of specimens, I have convinced 

 myself that the species cannot be classed under Mitromorpha, but 

 that its proper place is under Daphnella.
