THE GRAY MULLET OR THIN-LIPPED GRAY MULLET. 
MUGIL CAPITO. 
Fig. 90. 
Adipose membrane round the eyes only slightly developed. Height of 'the upper lip at most." about l / 16 ( 5'4 — G'3%) 
of the total length of the head , 9 — 10 l fi % of the length of the head behind, the eyes , about V 5 ( 19'2 — 20'6 %) 
of the length of the snout , about 1 / 5 (i7'V 2 — 20 %) of the breadth, of the mouth, or also about V 5 (10" 7 — 21’2% ) 
of the length, of the lower jaw. No tubercles on the surface of the upper lip. Length of the snout about x / 2 
(47 x / 2 — 50 x / 2 %) of the length of the head behind the eyes, which measures about 14 % (13 — 14' 2 %) of the length 
of the body, 60 % (57" 8 — 61' 3 %) of the total length of the head , 2 / 3 (71‘ 3 — 62' 8 %) of the greatest, depth of 
the body or 30 % (29' 5 — 32' 6 %) of the distance between the first dorsal fin and. the tig of the snout. Length 
of the lower jaiv and breadth of the mouth less than 56 % (the former 55 — 48' 5 %, the latter 54 l l 2 — 51 l f %) 
of the length, of the, head behind the eyes. Breadth, of the interorbital space at most 77 % (66 — 76'3 %) of the 
last measurement. Length of the head, usually more than 24 % (2.5’ 8 — 24 %) of the length of the body minus 
the caudal fin or than half (50 — 53 %) of the distance between the first dorsal, fin, and, the tip of the snout. Least 
depth of the tail less than 75 % (63 — 72 %) of the length of the head behind the eyes, but at least about 57 % 
(57 1 / 3 — 71 %) of the length of the pectoral fins, which measures at most about 15 % (1.5' 3 — 14‘3 % ) of the length 
of the body or 44 % (44f 2 — 41 %) of the distance between the ventral fins and, the tip of the snout. Base of 
the second dorsal fin less than (74 — 65 %) of that of the anal fin , than 3 /s (57 1 , l 2 — 53 %) of the length of 
the head behind the eyes or than 35 % (33' 7 — 31' 5 %) of the total, length of the head. Length of the ventral 
fins at least about 80 % (91 — 82' 7 %) of that of the pectoral fins. Continuation of the middle, groove of the 
roof of the pharynx scarcely visible in the anterior part of the roof of the palate, which is evenly concave with- 
out lateral, ridges ■ Middle carina of the tongue low. Hind extremity of the preorbital bone truncate, with both 
corners almost rectangular. Blind (lower) extremity of the maxillary bones externally visible even when the mouth 
is closed. Greatest, breadth of the chin-space as a rule greater than the breadth of either of the branches of the 
lower jaw at the hind extremity or at least equal to it.
