pp. Dark markings in the form of rounded spots, which 
are more or less confluent, sometimes reducing 
the pale ground color to narrow reticulations 
on a surface of black; ground color yellowish, 
the body covered with brown or black spots of 
varying size, never much smaller than the pupil 
of the eye, and sometimes so largely confluent 
as to make the ground color appear as yellow 
reticulations on a face of black; relative extent 
of light and dark markings subject to very great 
variations ; spots on head and snout generally 
. smaller; each pore on lower jaw generally 
placed in a large pale spot ; dorsal and anal 
fins spotted like the body ; margin of anal fin 
narrowly yellowish, this marking obliterated in 
dark specimens; teeth uniserial, irregular in 
size in the jaws, those in the front of the mouth, 
long, slender canines; vomer with one or two 
large, depressible teeth in front and usually a 
row of small teeth behind ; eye rafther large, 
about 2 in snout (2£ to 3 in dark specimens, the 
pigment encroaching on the cornea, so that the 
eye seems notably smaller) ; cleft of mouth 2£ in 
head ; head 2 to 3 in trunk ; tail usually a littke 
longer than the head and trunk. ..Moringa, 15.
