Family XXVII. SYNG.NATHID.lv. The Pipe-fishes. 
Body elongate, usually slender, covered with bony plates which are firmly connected, forming a 
bony carapace. Head slender, snout long, tube-like, bearing short toothless jaws at end. Gill-openings 
reduced to a small aperture behind the upper part of the opercle. Tail long, prehensile or not, 
usually provided with a small caudal fin. Male fishes with an egg pouch, usually placed on under 
side of tail, sometimes on abdomen, commonly formed of two folds of skin which meet on median line. 
The eggs are received into this pouch and retained until some time after hatching, when the pouch 
opens, permitting the young to escape. Dorsal fin single, nearly median, of soft rays only; pectorals 
small, or wanting; ventrals none; anal fin minute, usually present. 
a. Tail not prehensile, usually with a caudal fin; axis of head usually in line with axis of body. 
b. Top of head with a slight carination, or none. 
Syngnathinte; 
c. Pectoral fins present; caudal present. 
it. Male with egg pouch under tail, formed by lateral membranes which become connected along middle, forming a 
closed pouch. 
e. Dorsal fin inserted over or just before vent Siphostoma, 40 
dd. Male with egg pouch on abdomen; ridges of body prominent and distinct; caudal fin moderate. . . Dory'rhamphus 
cc. Pectoral fins wanting; caudal wanting or rudimentary; male with ova attached to abdomen, without closed pouch; 
no adipose fin. 
/. Back without peculiar tube Syngnathus 
ff. Back with a peculiar tube inclosed by the scutes, and extending for a distance before dorsal fin Osphyolax 
bb. Top of head strongly carinated... Cory'throichthys, 41 
IIippocampina;: 
aa. Tail prehensile; caudal fin small; head shaped like that of a horse, placed at a large angle with axis of body; egg 
pouch at base of tail.

Hippocampus, 42 
Genus 40. SIPHOSTOMA Rafinesque. The Pipe-fishes. 
Body elongate, very slender, 6 or 7-angled, not compressed, tapering into a very long tail; dorsal 
keels of the trunk not continuous with those of tail. Head slender, tapering into a long, tube-like 
subterete snout, which bears the very short, toothless jaws at end. Humeral bones firmly united with 
“breast ling.” Body covered with a series of bony, keeled, radiated plates, arranged in linear series. 
Dorsal fin distinct, rather short, inserted before or opposite th.e vent, which is near middle of body; 
caudal fin present, rather small; anal fin minute, close behind vent; pectorals developed, short and
