2. SYNGNATHUS BREVIROSTRIS, Grd. 
Short-nosed Pipe-fish. 
Spec. Char. —Head contained eight times in the total length : a little over twice in that of the body. Anterior rim of the 
orbit nearer the apex of the snout than the base of the pectoral fins. Longitudinal diameter of the orbit entering seven times 
and a half in the length of the side of the head. Origin of dorsal fin placed opposite the anterior edge of the anal aperture; its 
base, in the male sex, entering twice and a half times in the length of the body. Olivaceous brown, with darker maculae 
above and whitish dots beneath. 
Svn. —Syngnathus brevirostris, Grp. in Proc. Acad. Nat. Sc. Phiiad, VII, 1854,156. 
The total length of the specimen before us measures about six inches and a quarter ; the head 
forming the eighth part of it. There are eighteen plates anterior to the vent, and thirty-seven 
posterior to it. The base of the dorsal fin enters twice and one fourth in the length of the 
body ; the posterior margin of the same fin is nearly equidistant between the apex ot the snout 
and the extremity of the caudal fin. The length of the sub-caudal pouch is equal to the 
distance between the vent and the pupil.

Anterior rim of the orbit nearer the base of the pectoral fins than the apex of the snout. Longitudinal diameter of the orbit 
entering seven times and a half in the length of the side of the head. Origin of dorsal fin situated nearly opposite the anterior 
edge of the vent, rather posteriorly than anteriorly to that point ; its base, in the female sex, entering thrice on the distanoe 
between the concavity of thoracic belt and the posterior edge of the anal aperture. Dorsal region yellowish brown ; sides 
olivaceous and vermiculated ; abdomen yellowish.
