culus Ceti, juft as it was cut off the whale’s lip, with 
the feven naked Barnacles with ears, already de- 
fcribed. Fig. 7. a is the bottom of the (hell. This 
has the appearance of the gills of a mufhroom. All 
the fpaces between thefe lamina* were filled with the 
blubber of the whale : by this means they adhere to 
the griff ly fkin of the fifh. The narrow cavities be-

ligaments or tendons, that move the opercula, are

Fig. 8. is the Cup Barnacle, taken off an Eaff India 
fhip from Sumatra. The teftaceous flat bottom of 
this was marked with the feams and lines of the

his claws thro’ the opercula.
