5. Daphnella conquisita, n. sp. Plate IX, fig. 1. 



Shell small, fusiform, thin, fragile, semitransparent, spirally 

 lirate. Sculpture consists of narrow, sharply rounded and 

 elevated spiral ribs, narrower than the grooves, 4 on the spire- 

 whorls, 10 on the body-whorl, the interspaces radiately micro- 

 scopically finely striate. Colour light- fulvous. Spire elevated, 

 higher than the aperture. Protoconch formed by 2 smooth and 

 convex whorls. Whorls 6, regularly increasing, slightly shoul- 

 dered, flatly convex, base contracted. Suture impressed and 

 margined below by a small thread on the penultimate whorl 

 only. Aperture oblong-oval, margins nearly parallel, produced 

 below into an open, slightly flexuous canal, truncated at the 

 base. Sinus obsolete. Outer lip sharp, inside smooth, convex 

 above, concave on the canal. Columella sinuous, slightly pro- 

 duced in the middle, without any callosity. 



Altitude, 6 mm. ; diameter, 22 mm. 



Type to be presented to the Colonial Museum. 



A very well characterized species, in sculpture approaching 

 D. lacunosa, Hutt., which, however, has smooth grooves. 



6. Murex zelandicus, Q. and G. 



Voy. " Astrolabe," Zool., vol. ii, 1833, p. 529, pi. 36, figs. 5-7. 

 One live young specimen. 



7. Murex octogonus, Q. and G. 



Voy. " Astrolabe," Zool., vol. ii, 1833, p. 531, pi. 36, figs. 8-9. 

 A few specimens, one of them alive. 



8. Trophon curtus, Murdoch. 

 Trans. N.Z. Inst., vol. xxxvii, 1905, p. 228, pi. 8, fig. 22. 

 Two dead shells of this small species were obtained. 



9. Trophon pusillus, n. sp. Plate IX, fig. 2. 



Shell small, fusiform, fairly solid, imperforate, with nodulous 

 ribs. Sculpture formed by spiral and radiate rounded ribs, pro- 

 duced into oval nodules at the points of intersection ; there are 

 11 longitudinal ribs on the last whorl, but slightly narrower 

 than the interspaces, 2 spiral ribs on the upper whorls succeed- 

 ing the protoconch, 3 on the penultimate, and 10 on the last 

 whorl. From the base of the fourth whorl minute and close 

 radiate striae are beginning to ornament the whole surface of 

 the shell, most of the nodules remaining partly smooth. Colour 

 yellowish-white. Spire conical, a little shorter than the aper- 

 ture. Protoconch mammillate, smooth, consisting of 3 strongly
