. Zoology : for students and general readers . Zoology. THE PIPE FISH. 461 ton; a single opercular bone, while the snout and lower jaw are prolonged into a tube, with the mouth at the end. The chief peculiarity, however, is the gills, which are developed in the form of a row of tufted lobes on each side of the branchial arches. The scales are large, forming an- gular plates arranged in longitudinal rows (Gill). In Sole- nostoma of the Indian Ocean the female carries the eggs in a pouch formed by the union of the ventral fins with the integument of the breast. The male of the pipe-fish {Syngnathus fechianua Storer) receives from the female the eggs, and carries them in a small pouch under his tail, which is open beneath through its whole length. This sin- gular mode of mas- culine gestation is still farther per- fected in the sea- horse {Hippocam- pus Jiudsonius De Kay, Fig. 424), which lives off- shore from Cape Cod to Cape Hat- teras). The pouch is situated on the breast. The male, by simple mechanical pressure of its tail, or by rubbing against some fixed object, as a shell, forces the fry, to the number of about a thousand, out of its brood-pouch, the young at this time measuring about twelve millimetres (5-6 lines) in length. In the young the head is at first rounded, the snout being short and blunt (Lockwood). Ordei' 8. Plectognathi.—This group, represented by a few singular forms, such as the trunk-fish, file-fish, pufl:ers, and sun-fish, is characterized by the union of the bones of the upper and especially the lower jaws. There are few verte- brae, the scales are often modified to form spines, and the.
