length takes up at leaft a third part of the upper fide of the abdomen. In each fide of this 
figure, and in a right line, an angle is apparent ; hence a third part of the upper fide of the 
abdomen appears triangular. 
The arms are tuberous, globofe, and fprinkled with long and fliort hairs intermixed. 
The holders are blackifh. 
On the firfi; of September a fetnale was found, as reprefented in plate i , fig. 6. On the 
9th, fhe laid a parcel of eggs almofl: as big as a horfe-bean. The eggs, being flightly glued 
together, might be feparated with care. They were yellowifli, very large, and about fifty in 
number, wrapped up in black roughifli flue, faflened by threads of a footy colour within, 
but greyifh and loofe on the outfide. They feemed faflened to the wall of her cell. On the 
loth fhe was found in a dying flate, and dead on the i ith.

On the 22d of July, the fpecies reprefented on plate 2, fig. 5, was ready for copulation. 
Thefe may always be found in fine weather, but of different fizes. When they are full grown 
their colour and form change. They cafl their fkin three times. I fhould have doubted whe-

white down.
