Part I. 
Of Quadruped's. 
Three little LAN D-T ORTOISES of the fame 
kind. 
Another little LAN D-T O R T O I S E, of km to 
the former. ’Tisfomewhat rounder. 
A lelfer LAN D-T O R T O I S E, almoft circular and 
ridged on the back. 
A great CHE QJJ E R D TORTOISE-SHELL. 
Tefta Tefiellata major. It was fent from Madagascar. I 
find the Animal no where defcrib’d or figur'd. It is above 
half oval 5 being of all that I ever faw, the mod concave 5 
a foot long, eight inches over, and almoft fix inches 
high. 
The Convex 
is curioufly wrought with black and whitifh 
pieces, alternately wedged in, one againft another, and 
notched, as it were, with tranfvers Incifions. Thofe near 
the Margines and on the fides are compofed into feveral 
Pyramidal Area’s , or great Triangles, whofe Bafesare about 
two inches broad. On the Back, into fexangular ones,each 
of them convex. On the fides, and quite behind, the Shell 
is carry’d fomewhat inward. Before, and hinderly, the 
edges are toothed, and bended outward and upward. T he 
inward edges are cover’d with fhelly Plates above an inch 
and I broad. 
The Concave is compofed of fix and forty Bones. 
Along the middle of the Back, are twelve, all, except the 
foremoft and the four laft, almoft fquare. Next to thele, 
are eight on each fide, like to fo many contiguous Ribs 5 
together with two Idler fquare Bones before : Next to thcfe, 
eight more, as it were, under-Ribs, on each fide. To the 
twelve middlemoft Bones, the Ribs are joyned by an al¬ 
ternate commiifure, fo as one of them anfwers to the hafts 
of two Ribs, is vice verfa. Tothefe, the under-Ribs, in 
a wonderful manner, fell, by a branched Suture or Inden¬ 
ture. For the great Teeth of the under-Ribs, being firft 
inferted into thofe of the upper-Ribs ; the Indenture is af¬ 
terwards repeated, by idler Teeth, out ot the fides of the 
great ones. The Belly-piece is here wanting. 
Befides the molt elegant ordering of the Work in the 
Convex, there are three things chiefly obfervable, which 
ferve for the greater ftrength of the Shell. That is to fay. 
The Convexity of the feveral Areas on the Back, the
