base a specific description upon. It resembles Stilifer {Mucronalid) thomaiiae 

 Sowerby, of the West Indies, and is fixed to one of the arms of the criuoid. If 

 the species is hereafter recovered it might appropriately take the specific name of 

 bathi/metrae. 



Janthinidae. 

 JANTHINA (Bolten) Lamarck. 



Janthina, Bolten (first section) Mus. Boltenianum, 1798, p. 75 ; type, Helix janthina 



Linne; Lamarck, Prodrome, 1799, p. 75, same type. 

 lanthina Jeffreys, 1867, p. 174. 



The second section of Bolten's genus was composed of helices. Lamarck, the 

 following year, adopted Bolten's genus with its first species as type, and this 

 arrangement is universally accepted. 



Janthina pallida Harvey. 



Janthina pallida Harvey, in Thompson's Annals of Nat. Hist., 1817, 5, p. 96, pi. 2,

In 18S9, discussing the synonymy of this genus, I stated that tlie name given 

 by Bolten was a " pure catalogue name," having neither description or figure, and 

 for that reason did not adopt it But Bolten gives references to Gmelin's 

 description and the figures of Martini and Kuorr, and names thus validated, by 

 the general consent of naturalists and the development of the international code 

 of rules for biological nomenclature, have come to be considered admissible, and I 

 therefore have been obliged to modify niv views based upon the original code of 

 1842.
