larger in proportion to the fins in the older 
fifhes, as may be feen in Willughby’s 
Hiftory of Fifties, tab. B. 5. Thefe fpines 
give the fifh its name, and diftinguifh it 
principally from others of the Shark kind. 
The jfkin feemed very finooth to the 
touch ; though with a magnifying-glafs I 
could fee imall granula, which might in 
its growth produce a rough fkin. The 
teeth could not be felt; but with a glafs 
the rudiments of them might be feen, 
both in the gums and in the roof of the 
mouth. The fin of the tail is of a parti- 
cular fhape, as in other fifh of this genus : 
the back and tail fins are blueilh, edged 
with white. This and all other fifties of 
the Shark kind are faid to be (not boney, 
but) cartilaginous, like the Skate and Ray 
kind. 
Fig. 4, on the plate, reprefents the 
WALKING-STICK. It is fo much 
like a dry fiick, that it is fuppofed to de- 
ceive birds and other animals, that prey 
upon infers. The thicker part of the 
infed, neareft the head, where the fix legs 
are placed, is full of little prickles or thorns, 
like what are obferved on the branches of 
many forts of fhrubs and trees. The head 
refembles that of a Locuft with two horns. 
It is divided into joints the whole length 
of the body: but the laft joint or divifion, 
which is the tail, is only half-round, and 
hollow, appearing like the bark peeled off 
a flick. This was of a greenifh-brown 
colour; though I apprehend that they are 
at firft greener, and change gradually with 
age and the feafons, fo as to be always nearly 
of the colour of the earth, grafs, or fhrubs, 
on which they live. There are many dif- 
ferent fpecies of this infed both in the old- 
difcovered world and in America. Petiver, 
in his Gazophylacium, tab. LX. has given 
a figure of a lpecies different from mine, 
du dos, deux petits piquants tin eperons , qui 
deviennnet beaucoup plus grands d proportion 
des nageoires y aux poijfons qui font plus 
vieux *. Ges piquants donnent le mm au 
poijjdny et le diftinguent principaleme?it des 
autres fortes de Requins . La peau ma parti 
fort douce au toucher , quoiqu avec un micro - 
foope j'aye pu dijlinguer de petits grains s 
quiy d mefure que le poiffon grojftty peuvent 
rendre la peau rude. Je nai pu fentir les 
dents, quoiquon en put apperccvoir les ru- 
diment Sy avcc tin microfcopey tant aux gen - 
cfoqesy qua la par tie foperieure de la ma - 
choir e. La nageoire de la queue eft d'unc 
forme particidiere, commc dans tous les au- 
tres poijfons de ce genre. Les nageoires y tant 
du dos que de la queue , Jbnt bleudtres bordees de 
blanc . On dit que ce poiffouy aujjibien que 
toutes les autres efpeces de Requins , na point 
d'arreteSy mais des cartilages, comme le genre 
de Raves.
