place. This species is called by Mr. Hommel, the 
jaculator. , 
The length of the fish is about six or eight inches; 
the body is marked with five transverse brown bands 
with white edges ; the first band, which is not so 
broad as the others, passes across the head and 
through the eyes; the last across the base of the 
tail. , , 
The remarkable faculty which the rostrated chse- 
todon possesses is said to be found in some few 
others of very different genera.
