seem to be the authors of this mistake, as the two species are very distinct, 

 and at the place given Smith figured Adams and Angas's type which was 

 described in the same journal twelve years previously (p. 35) from Moreton 

 Bay, Queensland. 



As a matter of fact, from examination of types, I confirmed (Proc. Mai. 

 Soc. (Lond.), vol. ix, p. 73, 1910) Tryon's reference of Adams and Angas's 

 species to Murex tabiosus Wood, Index Test. Suppl., 1828, p. 15, pi. v, fig. 18. 

 I collected specimens at the Kermadecs agreeing accurately with both 

 the types named. As far as I know, the. species has not yet been found 

 in Neozelanic waters, but it probably lives there, and may have been over- 

 looked as the juvenile of some other species. 



Triton waterhousei (A. Adams and Angas, 1864). [P. 308.] 



This name is also given by Suter as a synonym of Cymatium spengleri. 

 I collected specimens at the Kermadec Islands which I immediately 

 differentiated from typical C. spengleri, and these were named C. water- 

 hovsei A. Ad. & Ang. for me by Mr. Hedley at Sydney. Mr. C. J. Gabriel, 

 of Melbourne, Victoria, showed me specimens which he contended were 

 gradations between C. waterhousei and C. spengleri. As my own series 

 was small, for this reason I did not record C. waterhousei from the Ker- 

 madec Islands. 



I have since received further specimens, and criticism of these in con- 

 junction with the type force the conclusion that this species is quite dis- 

 tinct from C. spengleri. Kesteven (Proc. Linn. Soc. N.S.W., 1902, p. 475) 

 also concluded that the two species were distinct, and gave what seem 

 very good differential characters. I do not think waterhousei has yet been 

 observed in Neozelanic waters. 



Argobuccinum tumidum (Thinker, 1862). [P: 309.] 



Ranella tumida Dunker. Proc. Zool. Soc. (Lond.), 1862, p. 239, Suter 

 has included in the synonymy of Argobuccinum argus Gmelin, of which he 

 gives as the range " Tasmania, Australia . . . Cape Colony . . . Chile." 

 The most casual examination of Cape Colony shells, which probably 

 Suter has not examined, convinced me of their distinction, the Cape 

 being the type locality of argus Gmelin. Hedley (Proc. Linn. Soc. N.S.W., 

 vol. xxxviii, p. 297, 1913), after examining the British Museum collection, 

 advocated the recognition of the Australia-Neozelanic form as a distinct 

 species, a course I emphatically endorse. The name given above is Hedley's 

 selection. 



Argobuccinuiii australasia Perry is also represented in South Africa 

 by a distinct species, which I have asked Mr. E. A. Smith, I.S.O., who is 

 much interested in South African shells, to describe. It differs at sight 

 in the coloration of the outer lip, the " leucostoma " having dark red-brown 

 teeth . 



Philippia (Gray, 1847). [P. 316.] 



As a subgenus of Architectonica Bolten, 1798, this name appears with 

 the reference " Philippia Gray in Philippi Enum. Moll. Siciliae, i, 174 ; 

 P.Z.S., 1847, 146. Type: Solarium luteum Lam." Here again I cannot 

 guess who is responsible for such a confusion of facts. 



In the Proc. Zool Soc. (Lond.), 1847, p. 146, Gray has written, 



' PhiKppia Gray, 1840 (Phil. Sicil., i, 174). Solarium, luteum, Lamk." 



Reference to Philippi's work shows that vol. i was published in 1836, not
