444 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
Habitat: West Indies, north to Key West, south to Bahia. 
Etymology: The plural of the Cuban name, cajt, formerly spelled caxi. 
This species is very abundant in the markets of Havana, where 
it is still known as caji (in old Spanish cart, of which “caxis” is a 
plural form), This persistence of the common name ithe only certain 
basis of identification of Parra’s Caxis. It is almost equally common 
~ at Key West, where, as in Catesby’s time, it is known as the “school- 
master.” The latter name is, however, indifferently applied by the- 
fishermen to Lutjanus joct also. 
There seems to be little doubt, in spite of the difference in color, which 
seems to be the fault of the printer, that the acutirostris of Duméril is 
tL. caxis, We have examined the original types of cynodon, linea, and 
jflavescens, which are identical with L. caxis. 
Peters adopts Schneider’s name albostriatus (apparently originally a 
mere slip of the pen for striatus), “because another species has been 
lately named Mesoprion striatus.” Peters identified Schneider’s type 
with “ Mesoprion linea C. & V.” 
This species is closely allied to Z. griseus and still more nearly te 
tL. joct. The latter is very similar in form and coloration, but has 
decidedly smaller scales. The former is more elongate, and has the 
vertical fins always dark, while in cazvis and joct yellowish colors 
predominate. 
Specimens of L. caxis are in the museum at Cambridge from Cuba, 
Sombrexo, and Jérémie, Haiti. A specimen from Pernambuco is more 
elongate (depth 22 in length), and the lower teeth a little stronger. 
_ We provisionally reject the name apoda, although older than cazis, 
because it may have been intended either for this species or jocw, while 
the bad figure must have been drawn from memory by Catesby. Not 
one fisherman in ten in the Florida Keys ean distinguish the “school- 
master” from the “dog snapper.” The fishermen of Cubaare, however, 
more skillful in separating their cajt from the joct.
