the eyes very large ; his snout not very unlike a parrot's bill, his upper jaw in- 

 cluding the under ; each foot has four sharp claws like a mouse. His belly is 

 made up of several thin scales ; whose middle pair are long and quadrangular, 

 that next the head and tail triangular, the rest irregular ; his tail taper, and 

 about half an inch long. His whole body exceeds not the half of a large 

 walnut.

The whole structure of this animal is very remarkable, and particularly his 

 eyes, viz. Between the fourth and last pair of clavs on each side, reckoning 

 from his mouth, and excluding the small pair there placed, are inserted the 

 rudiments of another pair, or a claw broken off on each side at the second joint 

 or elbow ; on these extremities are the eyes, like those on the horns of snails, 

 but being under the covert of a very thick and opake shell, nature in that place 

 has wonderfully contrived a transparent lantern, through which the light is con- 

 veyed, whose superficies very exactly resembles the great eyes of our large 

 libellge, or adderbolts, which to the naked sight are plainly perceived to be com- 

 posed of innumerable globuli ; these, like them, are oblong, and guarded with 

 a testaceous supercilium.
