The Harp shells, although few in species, are among the most showy of the marine snails. The shells are large and marked by many elevated ribs extending longitudinally, giving the effect of the strings on a harp, hence the name of the genus. The colors are different shades of brown which form neat festoons of dark brown lines between the ribs. The inner lip of the shell is marked by a dark brown spot and another spot is frequently developed near the upper part of the whorl. In one species (Harpa rosea) the shell is marked by several rosy spots and tints, and is very beautiful. The animal of this genus is no less interesting than the shell, being variegated with many beautiful colors. The foot is long, crescent shaped in front and becomes narrowed to a point behind. The animal is said to voluntarily break off a piece of its shell when irritated, as it is not able to retreat within the shell, being destitute of an operculum. It is very active and crawls about with an easy, graceful motion. Harpa lives only in the tropics and is found in the Indian and Pacific Oceans and on the west coast of America. The Bubble shells include within their number many curious and interesting animals. The typical genus, Bulla, numbers some fifty species of smooth, globular shells, frequently mottled like a bird’s egg. The aperture is as long as the shell and the outer lip is thin and sharp. The animal is large and fleshy and partly envelops the shell. The bubble shells love sandy mud flats in which they bury themselves or find concealment under masses of sea weed. Like many land shells they exude vast quantities of mucus to moisten their skin when the tide is out. These animals are carnivorous, living on bivalves and snails, which are swallowed whole and reduced to fragments by the huge, calcareous gizzard. Not all the mollusks of this order have true shells. The so-called sea hares, have large, flabby bodies in which is lodged a small, oblong, transparent shell. This animal lives among the sea weed, feeding upon the weed as well as upon mollusks and other animals. It discharges a violet liquid when handled which caused the ancients to believe that it was poisonous. The old Greek philosophers wrote a great deal on this subject, believing that to even touch the animal with a stick would cause death. Though repulsive looking creatures they are perfectly harmless and are even eaten raw by the natives of the Friendly and the Society Islands. Frank Collins Baker. JOIN A SUNRISE CLUB. Join a sunrise club? as is proposed in Birds and Nature for January. Of course I will. I have for years belonged to one of two members—my daughter and myself. Now we will transfer our membership to the new club that is to have members all over the country.
