Sitter. — Notes on New Zealand Mollusca. 331 



Nassa zonalis, A. Adams (1852). 

 Proc, Zool. Soc, 1851, p. 107 (publ. 1852). 



Specimens were collected at the Kermadec Islands by Miss 

 Robison, of Christchurch, and I am again indebted to Pro- 

 fessor W. H. Dall for naming them. They are much worn, 

 and it may well be that these, and perhaps several other species 

 that have been found washed up on the beach, were carried 

 down on seaweeds by currents from a northerly direction. It 

 seems most desirable that one or several good collectors should 

 stay at the Ksrmadecs for several months and thoroughlv 

 investigate the interesting fauna of that group, including dredg- 

 ing. For the present all we can do is to put on record all the 

 species found in the locality, leaving it to future workers to 

 weed out the species not really living in the group. Dead 

 specimens of Conus and Ci/pr&a have also been found at the 

 Kermadecs. 



Purpura striata, Martyn, n. subsp. bollonsi. 



This subspecies may shortly be described as a P. striata 

 in which the revolving cinguli are cut up by more or less deep 

 longitudinal sulci into distinct nodules, thus producing the 

 sculpture of P. emarginata, Desh. The colour of the shell and 

 interior of mouth is white, and the outer lip is strongly den- 

 ticulated. These two latter characters distinguish it from 

 emarginata, which, if really found in New Zealand, may be 

 a form of P. squamata, Hutton. 



Hab. — This very pretty subspecies was collected by Captain 

 Bollons, of the " Hinemoa," at the Kermadec Islands. Cap- 

 tain Bollons is well known as a most enthusiastic collector, doing 

 all in his power to further the interests of science, and I pro- 

 pose to name the subspecies in his honour. 



Type in my collection. 



Marginella albescens, Hutton (1873). 



Marginella albescens, Hutton, Cat, Mar. Moll. N.Z., 1873, p. 19 ; 

 Journ. de Conch., vol. xxvi, 1878, p. 22 ; Man. N.Z. Moll.. 

 1880, p. 62. M. infans, Hutton, Trans. N.Z. Inst., vol. xvi, 

 1884, p. 224 (not of Reeve). 



Hutton's name originally given to the species has to be 

 adopted again, as our shell is not the same as Reeve's infans, 

 which occurs near Singapore. No doubt Captain Hutton fol- 

 lowed Tryon in identifying his species with that of Reeve. 

 Further, M. pellucida, T. -Woods, is not a synonym of infans 

 or albescens either.
