Dosinia subrosea (Gray, 1835). [P. 979.] 



As synonyms, Hedley (loc. cit., p. 270) has added Dosinia coryne A. 

 Adams, Proc. Zool. Soc. (Lond.), 1855, p. 223 (1856) ; D. crocea Deshayes. 



Genus Antigona (Schumacher, 1817). [P. 983.] 



1 have recorded (Proc. Zool. Soc. (Lond.), 1914, p. 668) that when Dall 

 revived Cytherea of Bolten, 1798, for this genus he overlooked the fact that 

 it was invalid, as there was a Cytherea Fabricius, 1794. I added, Antigona 

 was older than Antigonus Hiibner. quoted as of 1816, but not published 

 until 1820, and therefore the correct name, providing that the other data 

 recorded by Dall and Jukes-Browne and their conclusions were accurate. 



I doubt the reference of he Neozelanic shell Dosina zelandica Gray to 

 this genus. 



Antigona zelandica (Gray, 1835). [P. 985.] 



As the basis of Cytherea oblonga, Suter has given ^ Venus oblonga Hanlev 

 in Wood's Index Test., Suppl., ' 1828." Wood's Index Test,, Suppl., was 

 published in 1828, but Hanley's Descr. Cat, Rec. Shells, also described 

 as a 2nd edition of Wood's Index Test,, did not appear until 1842, and was 

 not completed until 1856. On Hanley's Supp., pi. xvi, fig. 1, "Venus oblonga 

 Hanley (Dosina o. Gray) " was given : this plate was published in 1844. 

 In 1856 the text to this appeared, and on p. 359 Venus oblonga Hanley 

 is described. This is simply Dosina oblonga Gray, 1843, placed in the genus 

 Venus, and as a synonym is quoted " Dosina zelandica Gray, 1835, fide 

 Deshaves." 



In the Appendix to Yates Ace. New Zeal., p. 309, Gray describes some 

 new species of shells, one of which was Dosina zelandica. The preface 

 to this work is dated the 10th August, 1835. This name has priority, and 

 must now be used. It was dropped on account of the reference of all the 

 species to Venus when it clashed with Venus zelandica Quoy and Gaimard, 

 published in the same year as Gray's name but earlier. As, however, both 

 were introduced as belonging to different genera, and both are still recog- 

 nized as referable to distinct genera, both names must be maintained. 



W T hen Gray introduced his species he added, " The Dosinae have a 

 small anterior additional tooth on the hinge margin. Lamarck refers them 

 to Venus : they are intermediate between Venus and Cytherea." This is 

 the first introduction of the genus-name Dosina. and by monotvpy it be- 

 comes the type. The name is over twenty years older than Ventricola 

 Romer, 1857, used for this section by Jukes-Browne, but cannot be used 

 on account of the prior Dosinia Scopoli, 1777. Dosina Gray has been 

 generally cited as of 1838. and a different type noted. 



Chione spissa (Deshayes, 1835). [P. 991.] 



Venus crassa Quov and Gaimard. 1835, is antedated by Venus crassa 

 Gmelin, Syst. Nat,, 1791, p. 3288. 



Suter's first synonym reads, " V. spissa, Deshayes A.s.V., ed. 2, vi, 

 373 (misprint for crassa)." Investigation of this name has given extra- 

 ordinary results. Reference to Deshayes shows that he was not aware 

 of the specific name given by Quoy and Gaimard, but that he described 

 the shell from the figure given in the " Astrolabe Atlas,'" and simply trans- 

 lated the vernacular there added. The title-page of the atlas is dated 1833, 

 which indicates that the plates were issued before the text, as that is dated 

 1835. The vernacular on the plate is Venus epaisse, and this Deshayes
