STURGEON.—[Aiipenser attilus. affords so large a quantity of gelatinous matter, that one part of isinglass dissolved in a hundred parts of boiling water will form a stiff jelly when cold. Caviare is made from the roe of this 6sh, and as nearly three millions of eggs have been taken from a single fish, the amount of caviare that one Sturgeon can afford is rather large. The body of the Sturgeon is elongated, and slightly five-sided from the head to the tail. Along the body run five rows of flattened bony plates, each plate being mark- ed with slight grooves in a radiating fashion, and having a pointed and partly conical spine on each plate, the points being directed to Awards the tail. The plates along the sum- mit of the back are the largest. The fishes belonging to the next group have their gills fixed by their outer edge to the divisions in the gill-openings at the side of the neck. This group includes the Sharks and the Rays, many representatives of which creatures are found on the British coasts. The first family of this large and important group is known by the name of Scyllidffi, and its members can be recognized by several distinguishing characteristics. They have spout-holes on the head, and the gill-openings are five in number on each side. Sometimes there only seem to be four openings, but on closer examination the fourth and fifth are found set closely together, the opening of the fifth appearing within that of the fourth. The teeth are sharp and pointed, and the tail is long, notched on the outer side, and is not furnished with a fin. One of the commonest British species is the Little Dog-fish, called by several other names, as is usual with a familiar species that is found in many localities. Among such names are Small Spotted Dog-fish, Lesser Spot- ted Shark, Morgay, and Robin Huss. This fish is plentiful on our coasts, especially in the southern extremity of Eng- land, and is often thought a great nuisance by
