employed the noineiicluture of Eang for this type, has described 

 mandibles, and O'Donoghne (1921) states : ' The radula and 

 jaws or any representatives of such structures are entirely 

 absent.' Although O'Donoghue (1921) also employed the 

 nomenclature of Gould for the genus M e 1 i b e , in a su])sequent 

 letter to me he states : ' I have quite given up Chioraera 

 as a name.' In recent publications by this author (1922 : 

 125; 1922 a: 165) and by O'Donoghue (1922: 184) it is 

 suggested in a foot-note that Melil)e leonina would be 

 a 'better' name than Chioraera leonina. Neither 

 Cooper, Fewkes, nor Heath made an intensive study of the 

 type ; this is evident from their descriptions. A careful study 

 of Gould's Chioraera has brought out sufficient reason to 

 merge it with Melibe as indicated by Tryon, Jr. (1883), 

 Bergh (1908), and Agersborg (1921 a). The structures and the 

 general characteristics of Chioraera leonina Gould, 

 correspond in many details with those of the Melibes of Eang, 

 Bergh, e t a 1 . For this reason I have adopted the name as 

 indicated by Tryon, Jr., and also suggested by my friend. 

 Professor Trevor Kincaid, viz. Melibe leonina (Gould) 

 as indicated in the title of this work. (Vide Agersborg, 1921 a, 

 1922rt, 1923.)

 LEO XIX A Gould). 



The type of the genus Melibe was discovered at the Cape 

 of Good Hope and was described by Eang in 1829. Since that 

 time a number of species (vide supra) have been added by 

 various authors.^ In 1852 Gould described Melibe (s. 

 Chioraera) leonina from Puget Sound, founding for it 

 the genus Chioraera, now merged with Melibe. In 1914 

 I observed this animal at the Puget Sound Biological Station 

 (vide Agersborg, 1916, 1919, 1921, 1921a, 1922, 1922o, 1923). 



^ My designation of Melibaea australis Angas (186-4), as 

 Melibe australis (Agersborg, 1919, 1921) is not justified, as indicated 

 by the description of Angas. His description seems to fit the genus 

 Doto (vide Kjerschow Agersborg, 1921).
