Genus Clanculus Montfort, 1810. 

 Clanculus ringens (Menke, 1843). 

 talcapunensis (Webster. 1906). 



Section Melagraphia (Gray, 1847). [P. 115.] 



This name must displace Neodiloma Fischer, 1885. It appears to have 

 been quite overlooked, as it appears in no recent synonymy I have ex- 

 amined, nor is it included in Scudder's Nomenclator. It is introduced 

 in the Proc. Zool. Soc. (Loud.), 1847, p. 145, as of " Stentz, 1836," for 

 Tr. aethiops Gmel. alone. I have been quite unable to trace any publica- 

 tion by Stentz, and have concluded its reference to Stentz implies manu- 

 script usage only. I observed Philippi referred to other names given by 

 Stentz in manuscript to shells in the Berlin Museum. 



Labio concolor (A. Adams, 1853). [P. 116.] 



Eliminate this name from the synonymy of Monodonta aethiops Gmelin, 

 1791, as examination of the types, preserved in the British Museum, show 

 the locality given to be incorrect, the shells being a form of Trochus lineatus 

 Da Costa, a shell I have collected at Torquay, England. 



Labio rudis (A. Adams, 1853). [P. 117.] 



This is the earliest name given to the " corrosa " group by A. Adams, 

 the locality "Australia" being incorrect. It has one page priority over 

 L. corrosa, but the name is invalidated by the prior Mondonta rudis Gray 

 in King's Survey Coasts Austr., App., p. 480, 1826, which appears to me to 

 be identical with and have priority over the Western Australian melanoloma 

 Menke. It is possible that Labio rudis has been placed in the synonymy 

 of the Western Australian species, but examination of the types show them 

 to be the commonest form of corrosa," such as is easily collected in the 

 Heathcote Estuary, Christchurch. 



Trochus acuminatus (Perry, 1811). [P. 124.] 



This synonym of Cantharidus opalus Martyn, 1784, is not included by 

 Suter. In Perry's " Conckology," pi. xlvii, fig. 1, an easily recognizable 

 figure is given. 



Cantharidus capillaceus (Philippi, 1848). [P. 125.] 



Suter has used the later C. pruninus Gould, 1849, though including 

 the present name in the synonymy. In the Man. Conch., 1st ser., vol. xi, 

 p. 122, 1889, Gould's name was preferred, but that was due to a mistake 

 in dates, the Otia. Conch., p. 55, being quoted as " 1846," though the earliest 

 publication of the name is that given by Suter, and the date 1849 is correct. 



Cantharidus capillaceus subsp. perobtusus (Pilsbry, 1889). [P. 125.] 



Omit from the "Hab." "Sandfly Bay, Otago Peninsula (T. Iredale)." 

 That refers to the shell I described as Photinitla decepta, which was named 

 as above by Mr. Suter. 



Cantharidus capillaceus var. minor (E. A. Smith, 1902). [P. 125.] 



From examination of the types, I believe this to be a distinct species, 

 which I will deal with later.
