Entrochi, and Asterice, I shall consider them, and shall most com- 

 monly speak of them, as VERTEBRAE, joined or disjoined; and penta- 

 gonal or cylindrical : and instead of stirts or wirks, we shall mark the 

 processes which go off laterally from the trunk, by the terms VERTE- 

 BRAL APPENDICES. 



The basin formed at the superior part of the trunk, Ly that which 

 is termed the pentagonal base by Rosinus, and in which there is every 

 reason to suppose, that the organs for the reception and the digestion 

 of aliment were placed, I shall term the PELVIS: and the sub- 

 stances, fay which it is formed I shall consider as RIBS, CLAVICLES, 

 and SCAPCJLTE. The articulated parts, not longitudinally divided, 

 proceeding from these, I shall consider as the ARMS; when divided, 

 the HANDS formed of two fingers; and the innumerable, articulated 

 appendices, proceeding from these, the TENTACULA. The remains of 

 the vertebral column of these animals are so numerous, and at the 

 same time so varying in their forms ; and, in consequence of their 

 being seldom found united to the other parts of the animal, can so 

 rarely be classed, with any certainty, with the species to which they be- 

 long, that it appears to be advisable to examine them first generally, 

 and afterwards to point out, as nearly as may be, those which belong 

 to the several species of this animal which may fall under our ob- 

 servation. 



Small stony bodies of a circular form, some very thin, others cy- 

 lindrical, and others almost orbicular, marked on their flat surfaces, 

 with minute striae ; and on their margins, with small indentations and 

 projections, have been long found in the earth, in different parts of the 

 world, and have acquired different names, according to the whims 

 and caprice of the vulgar. In Germany, they have been named Span- 

 gensteines, from their likeness to the beads of a necklace ; and Roeder- 

 steines, from their rays passing from the centre to the circumference 

 like the spokes of a wheel. In Upper Saxony, they are known by the 

 appellation of Bonifacius Pfenninge, or St. Bonifacius's money ; they
