MUGIL STEVENS! sp. nov. 
STEVENS' GEAY MULLET. 
* Sc. 31 — 11. Dorsal contour feebly arched, much less so than 
the ventral ; greatest depth, below the spinous dorsal, 31, length of 
head 4 in the length of the body. Upper profile of head moderately 
convex to between the eyes, linear and but little oblique behind 
them. Upper lip thin and curved, with its upper edge continuous 
with the snout, the depth of its vertical portion less than half the 
diameter of the eye ; lower border formed by a pair of convex lobes, 
separated by a moderate symphysial notch. Jaws with a single 
series of fine cilia. Maxillary extending to below the posterior 
nostril, curved downwards and slightly swollen distally, entirely 
hidden beneath the preorbital. Snout broad, emarginate in front, 
scaly, -| of the diameter of the eye, which is 3| in the length of the 
head. Adipose eyelid narrow anteriorly, much wider and almost 
reaching the iris posteriorly. Interorbital region convex, its width 
2 in the length of the head. Preorbital scaly, its outer border form- 
ing a widely obtuse angle, denticulated throughout its entire length 
with the exception of a short, smooth area immediately in front of 
the distal angle; the denticles increase in size posteriorly, those 
behind the angle, especially the last three, being very strong; it 
forms an acute angle with the distal border, which is feebly convex 
and finely serrated. Depth of cheek below the middle of the eye f- 
of the diameter of the eye. Rami of lower jaw meeting at a widely 
obtuse angle, separated by a deep mesial groove, and naked 
anteriorly. Free intermandibulary space rather small and cunei- 
form. Angle of preopercle produced; interopercles in contact; 
opercles smooth, fcpinous dorsal originating above the llth. body- 
scale and nearer to the base of the caudal than to the tip of the 
snout ; spines strong, the 1st. much higher than the 2nd. and If in 
the length of the head : soft dorsal originating above the 20th. body- 
scale, its distance from the origin of the spinous equaling the head. 
Anal originating below the 17th. body-scale ; space between its 
origin and that of the soft dorsal rather more than the head ; basal 
length f of its distance from the caudal. Caudal emarginate, with 
12 branched rays, the middle pair about f of the outer and 5^ in the 
* The dorsal and anal fins are so much injured that it is impossible to count the 
number of soft rays.
