PISCATKIX. 
and if these had been correctly determined, three generic names would at 
once have been available, but unfortunately neither the species nor the 
genera were accurately fixed. 
First, as type of Sula Brisson is given Sula sula ; as the type of 8ula 
Brisson by tautonymy must be Sula of Brisson, which equals Pelecanus 
leucogaster Boddaert, Ogilvie-Gr ant’s statement reads wrongly, and his identifi- 
cation of Sula sula was wrong, but his statement is right, the name used 
being wrong. Then the type of Dysporus Illiger is stated to be Sula hassana, 
but as lUiger’s name was simply a classical substitute for Sula Brisson, the 
type must be that of Brisson’s genus. Moms Vieillot is given as of the 
Nouv. Diet. d’Hist. Nat. 1817 and the type named S. sula, but that name 
was proposed by Vieillot in the Analyse nouv. Ornith. 1816, and the type by 
monotypy is Pelecanus bassanus Linne. 
Plaucus Bafinesque, Analyse, p. 69, 1815 : Beichenb. Av. Syst. Nat., 
p. vi., 1850. Type S. hassana ” is included, but Bichmond {Proceedings U.S. 
Nat. Mus., Vol. XXXV., p. 633, footnote, 1908) has observed: “ Plancus of 
Bafinesque, a nomen nudum, is one of ‘ Les Bapaces ’ of that author, 
and placed in the ‘ Sous-famille Ptiloderia, Les Nudicolles ’ near Vultur. 
Grant {Catalogue of the Birds in the British Museum, Vol. XXVI., p. 423), 
synonymizes it with Sula ! ” 
Beichenbach’s name was also spelt Plancus. 
In view of such confusion the only possible method is to begin at the 
beginning and make out what I consider to be a correct fist of names. The 
references are given in detail in my synonymy : 
Sula Brisson 1760 
Sula Scopoli 1777 
Sula Lacepede 1799 
Dysporus Ilhger 1811 
Sularius Bafinesque 1815 
Morus Vieillot, April 1816 
Moris Leach 1816 (August) 
Moris Forster 1817 
Dysporus Beichenbach 1852 
Piscatrix Beichenbach 1852 
Sula Beichenbach 1852 
Plancus Beichenbach 1852 
Aheltera Heine 1890

New name for Sula Brisson. 
New name for “ Sula Lac.” 
Type P. bassanus Linne\ 
Nomen nudum and = 
= Morus VieiUot. 
= Dysporus Illiger. 
Type P. candida=P. sula Linne. 
Type P. leucogaster Boddaert. 
Type P. bassanus Linne. 
New name for “ Sula Bchb.” 
The above needs a Httle explanation. Sula was first proposed by Brisson, 
a non-binomial writer, and as one of his species was named “ Sula ” alone.
