2. LUTJANUS VIRIDIS. 
Diacope viridis Valenciennes, Voyage de la Vénus, 1845, 303, pl. 1, f. 2 (very bad) 
(Galapagos Islands). 
Genyoroge viridis, Giinther, 1, 180 (copied). 
Luljanus viridis, Jordan, Proceedings U. 8. National Museum 1888, 330 (Tres Matias), 
Habitat: Galapagos, Tres Marias, and Revillagigedos islands. 
Etymology: Viridis, green, a very inappropriate name, as the species 
is brown with blue stripes. 
This interesting species is a near ally of Lutjanus kasmira (Forskal) 
(=. bengalensis Bloch). It belongs to the subgenus Yvoplites, a group 
well represented in the East Indies, but with no other American allies. 
A single specimen was obtained by Alphonse Forrer, from the Tres 
Marias Islands, near Mazatlan. Several others have been since taken 
by Dr. C. H. Gilbert at the Revillagigedos Islands, where it is very 
abundant. 
Lutjanus kasmira (from Swatow, China) differs from Lutjanus viridis 
in the following respects: Body deeper (depth 22); scales smaller (8) 12- 
2-22; the back more elevated and the profile steeper; snout, 3 in head; 
preorbital, 6; maxillary, 2%; second anal spine, 5+; lower lateral band 
wanting; a vague dark lateral blotch present, larger than eye; bands 
less sharply defined than in JL. viridis, the pale-blue median streak in 
each band twice as wide as the dark border, the whole band narrower, 
its width one-third to one-fourth that of the golden-brown interspaces; 
no median dorsal streak. 
3. LUTJANUS CANINUS. 
? Mesoprion pargus Cuy. & Val., 11, 473, 1828 (Puerto Rico). - 
Genyoroge canina Steindachner, Ichthyol. Notizen, 1x, 18, 1869 (Lagos, Brazil). 
Habitat: Brazilian fauna. 
Etymology: Caninus, doglike, a reference to the canine teeth. 
Steindachner’s description of Genyoroge canina agrees in all respects 
with the young of Lutjanus cyanopterus, except that the preopercle in 
I. caninus is said to have the deep emargination found in L. viridis 
and in the group called Genyoroge. We accept it provisionally as a 
distinct species, solely on this character. The scanty description of M. 
pargus probably refers to a specimen of L. cyanopterus, but the state- 
ment “le tuberosité de son interopercule est assez prononcé” suggests” 
I. caninus. The type, probably a dried skin, we have failed to find in 
the museum in Paris.
