Wien, 13(1. xiv. pp. 717-720). IFo lias found ilmt this spider digs its burrow 
at night only, and that each grain of earth when detached is carried away to 
some distance from the mouth and there deposited. A complete burrow 
descended perpendicularly for inches; from the bottom a nearly horizontal 
gallery was given of!’, which terminated in a wider chamber, containing an 
egg-sac with 286 eggs. In one case the spider in sinking its burrow had 
come upon a flat stone of considerable size ; the burrow was then diverted, 
carried round the edge of the stone and along its lower surface so as to 
descend below it in the same line as that of the upper portion. The males 
do not make any burrows ; Erber describes their habits and the stratagems 
they employ to get at the females, from which he believes not more than two 
or three out of ten escape with life. The food of the Tarantula consists of 
insects of all orders, and spiders.
