The PICKED-DOG. Galeus Acanthias. Because he hath two strong and sharp Spikes growing on his Back, behind the two Finns, and pointing towards his Tail. See the Description in Salvianus and Rondeletius. Besides the two Finns which grow on each side the Anus, the Males, saith Salvian, (b) (b) Hist. 42. have also two Appendices, one on each side the Anus. But betwixt the Anus and the Tail there is no under-Finn; by which he differs from the rest of the Dogkind. He is said scarce to grow so big, as to exceed twenty pounds in weight. His Skin is rough with the like Prickles, as in the former; so small, as scarcely visible without a Microscope. But easily felt by drawing your hand towards the head. The shape also of the Teeth is odd and unusual, being armed with little sharp Hooks on each edge. They are taken sometimes upon our English Coast.

The Anatomy of the Galeus (the Male) is given us by Sir George Ent, in Dr. Charleton's Onomastic. Zoic. Some of the most observable Remarks, are the peculiar shape of the Pancreas, and especially the Spleen, having a Label produced from one side, above twice its own length. Likewise the Purse at the farther end of the Duodenum, into which it opens only by a very small round Hole, not so wide as to receive the end of ones little finger: all which are described and figur'd. He hath also growing on the lower Eye-lid, a thick and firm Membrane, wherewith he often winkles or covers his whole Eye: the same with that called the Periophthalmium, common to very many Birds.

The Description of the Viviparous Eggs in the Female; which are not unlike to those of the Raya, is given by Rondeletius. Bellonius hath seen an indifferent One, to bring forth thirteen young ones at a Birth. So soon as ever she hath brought them forth, they swim along with her, and if any of them are afraid of any thing, it runs immediately into the Mouth, say some, into the Womb of the Dam: when the fear is over, returns again, as if by a second Birth.

The Skin is used for the polishing of Wooden and Ivory Works.
