. A guide to the study of fishes. Fishes; Zoology; Fishes. 238 Phthinobranchii tail of a sea-horse. Most of the living species of the sea-horse belong to the genus Hippocampus. These little creatures have the egg-sac of the male under the abdomen. They range from two inches to a foot in length and some of the many species may be found in abundance in every warm sea. Some cling by the tails to floating seaweed and are swept to great distances; others cling to eel- grass and live very near the shore. The commonest European species is Hippocampus hippocampus. Most abundant on our Atlantic coast is Hippocam-pus hudsonius. Hippo- campus coronatus is most common in Japan. The largest species are Hippocampus ingens of Lower Cali- fornia and Hippocampus kelloggi in Japan. Many species, especially of the smaller ones, have the spines of the bony plates of the body ending in fleshy flaps. These are sometimes so enlarged as to simu- late leaves of seaweed, thus serving for the efficient protection of the species. These flaps are developed to an extreme degree in Phyl- lopteryx eques, a pipefish of the East Indies. No fossil sea-horses are known. The following account of the breeding-habits of our smallest sea-horse (Hippocampus zosterce) was prepared by the writer for a book of children's stories: "He was a little bit of a sea-horse and his name was Hippo- campus. He was not more than an inch long, and he had a red stripe on the fin on his back, and his head was made of bone and it had a shape just like a horse's head, but he ran out to a point at his tail, and his head and his tail were all covered with bone. He lived in the Grand Lagoon at Pensacola in Florida,. J?IG. 1S9.—Sea-horse, Hippocampus hvdsonius Dekay.
