432 REPORT OF COMMISSIONER OF FISH AND FISHERIES 
1. HOPLOPAGRUS GUNTHERI. (Pargo.) 
Hoplopagrus giinthert Gill, Proce. Ac. Nat. Sci. Phila. 1862, 253 (Cape San Lucas) ; 
Steindachner, Ichth. Beitriige, v1, 1878, 1 (Altata); Jordan & Gilbert, Bull. 
U. S. Fish. Comm. 1882, 107, 112 (Mazatlan, Punta Arenas); Jordan & 
Swain, Proc. U.S. N. M. 1884, 429 (Mazatlan); Evermann & Jenkins, Proc- 
U.S. N. M. 1891, 145 (Guaymas). 
Habitat: Pacific coast of tropical America, from Guaymas to Panama. 
Etymology: Named for Dr. Albert Giinther. 
This remarkable species is a common food-fish of Mazatlan, where 
it is known as the “pargo.” The specimens examined by us are from 
Mazatlan and Guaymas. Dr. Gill has very properly considered it the 
type of a distinct subfamily, Hoplopagrine. Its peculiarities are cer- 
tainly stronger than those of the other genera associated with Lutjanus, 
although in the structure of the cranium itself it does not materially 
differ from Lutjanus. 
Subfamily II1.—LUTJANIN. 
II. LUTJANUS.

Type: Lutjanus lutjanus Bloch, an Kast Indian species. 
Ktymology: From Ikan Lutjang, a Japanese or Malayan name of the 
species. 
This is a very large genus, the most extensive in the family, even 
after the separation as distinet genera of numerous aberrant forms. 
Perhaps the group may admit of further subdivision, but this can not 
be carried out without a wider knowledge of it than we now possess. 
The peculiar notching of the preopercle on which the genus Genyoroge 
has been based is certainly a character of minor importance, as it disap- 
pears by degrees in different species. Most European writers have 
called this genus Mesoprion, after Cuvier. This is an unnecessary viola- 
tion of the law of priority, as Lutjanus aud Dipterodon are both prior 
to Mesoprion.
