Hab.—Rsiwke's Bay; C. H. Weber, Esq., 1878. 



A species near to R. ursus, but much larger. 

 Rhyncodes rubipunctatus, n. sp. 



Insect -wholly covered with very short whitish-grey down, finely and 

 thickly speckled with light-red, which (below especially) assumes a flattish 

 semi-scaly appearance, each minute speck of reddish down or hair showing 

 a regular circumscribed shape ; pronotum dotted profusely and finely with 

 black raised irregular dots, and bearing two semi-lunate and two smaller 

 brown spots ; elytra extending sharply over abdomen, with 12-14 longi- 

 tudinal sub-striated rows of black raised shining dots, mottled with 2-3 

 small brownish markings in a line with those on pronotum ; abdomen below 

 with three fine transverse black lines near anus ; head between eyes and 

 base of rostrum coarsely dotted with raised brown dots ; eyes large ; rostrum 

 jet-black, smooth ; antennm as long as rostrum and slightly hairy. Length,

 it to bleed. 



Aet. XLI. — Descriptions of New Shells. 

 By T, W. Kirk, Assistant in the Colonial Museum. 

 [Bead before the Wellington Philosophical Society, 21st January, 1882.] 

 The three species mentioned below all possess a deep notch at the anterior 

 end of the columella, which at once distinguishes them from Euchelus, the 

 columella of which has only a " small tooth in front." It thus becomes 

 necessary to create a new genus for the reception of the New Zealand 

 species. 



Professor Hutton, to whom I have dedicated the new genus, informs me 

 that while in Sydney he examined a series of specimens representing the 

 various species of Euchelus, but in no instance could anything approaching 

 a notch be discovered. 



HuTTONiA, gen. nov. 

 Shell moderate ; turbinated, sub-globose ; perforate or imperforate ; 

 columella with a deep notch at the anterior end. Outer lip thickened and 

 crenated internally. 

 H. hella. 



Euchelus bellus, Hutton ; Cat. Marine Moll., p. 37. 

 H. tricolor, sp. nov. 



Shell imperforate ; larger, spire more prominent, and granulated ribs 

 much coarser than in H. bella.
