HOMEA. o49 
Homea the typical genus (Bdellostoma of Miiller, 1854) was based on a spe- 
cies, taken by Banks in the South Seas and noted by Home in 1815, to 
which the generic and specific names Homea Banksii were applied in 1822. 
Species of this genus, Gastrobranche Dombey LaC. and Petromyzon cirrhatus B. 
S. were placed by Cuvier, 1829, in “Les Heptatremes Dumér.” In 1831 
Bonaparte made “ Heptatremus Dumér.” a synonym for Myxine, and in 
1832 Voigt translated Cuvier’s terms into “ Heptatrema Duméril,” including 
the species originally assigned. Johannes Miiller, 1834, renamed the genus 
Bdellostoma and made it to contain the species placed in it by Cuvier with 
several others since reduced to the synonymy. Girard’s statement that 
the name Heptatrema was given by Duméril in 1806 is without warrant; 
and “ Gastrobranche,” 
? 
the generic names then applied were “ Lamproie’ 
the Latin terms Petromyzon and Gastrobranchus were placed after these in 
parentheses in 1812, when Ammoceetus was added as another genus. Unless 
it can be shown that there was use of the name Heptatrema previous to 1822 
it will have to give way to Homea. That Bdellostoma was a synonym was 
known to Miiller is evident from his references. The family name £dello- 
stomide 1872, was discarded by its author for Heptatremide, 1894 ; both, being 
based on synonyms, will have to be dropped for Homeide. Crediting the 
family name Myxinde to Rafinesque, 1810, is probably due to mistake pos- 
sibly based on that author’s “ LXXI. Ordine J. Missinidi,” which being with- 
out contents is only an empty name. Rafinesque’s subfamily Myzinia of his 
family Cyclostomia dates from 1815, the name Myzinide dates from 1845. 
The family was well established by Miiller 1835 (1834) under the name 
Myzxinoidea and included both Myzxinide and Homeide.

The history of this genus begins with the article in the Philosophical 
Transactions for 1815, in which Home records a number of particulars con- 
cerning a specimen obtained by Banks, page 258, Tab. XI. fig. 1. The 
species is identified by Giinther and others with that described by Bloch 
and Schneider, 1801, from manuscript by Forster, under the name of Petro- 
myzon cirrhatus. The name Homea Banksii was applied to it by Fleming,
