DESCRIPTION OF A NEW SPECIES OF HEMIRHAMPHUS (HEMI- 
RHAMPHUS BROS), FROM THE COAST OF CALIFORNEA. 
By DAVID S. JORDAN and CHARLES H. GILBERT. 
Hemirhamphus rose, sp. noy. 
Allied to Hemirhamphus wnifasciatus and other typical species of the 
genus. 
Body rather elongate, moderately compressed; the greatest depth 
being one-ninth of the length from the snout to the base of the caudal. 
Length of the whole head, including the lower jaw, contained 22 times 
in the length from tip of lower jaw to base of caudal. Length of the 
lower jaw beyond the tip of the upper jaw 44 times in the same length. 
The length of the head from the tip of the upper jaw is contained 34 
times in the trunk (without head or caudal). 
The triangular part of the premaxillaries is convex, slightly carinated 
above, and about as broad as long. The eye is rather large, somewhat 
less than the interorbital space, and about half of the postorbital part 
of the head. Mandible elongate, the narrowed tip slightly bent down- 
ward; the bone bordered on each side for its entire length by a con- 
spicuous membrane, the membranaceous part being about as wide as the 
bony portion itself. Upper surface of mandible convex, grooved. Teeth 
in both jaws small, even, all of them apparently unicuspid. Top of head 
nearly plane, very slightly convex. Preorbital rather long; its diameter 
two-thirds that of the eye. 
Seales rather small, very deciduous, about 63 in a longitudinal series. 
Fin rays: D. I, 13; A. I. 14. 
Dorsal and anal fins not at all scaly; the dorsal a very little longer 
than the anal and inserted slightly in front of it; the anterior rays of 
dorsal and anal moderately elevated. Caudal fin moderately forked; 
the lower lobe the longer; the middle rays nearly twice the diameter of 
the eye. Pectoral fin a little longer than the postorbital part of the 
head. Insertion of ventral fin slightly nearer the tip of the caudal fin 
above than the eye, and midway between the gill-opening and the base 
of the caudal. Ventrals a little shorter than the postorbital part of the 
head, not reaching vent.
