entrance closed by the trapdoor, except for which a few could be 

 easily mistaken for "turrets" of Atypoides. In these above- 

 ground extensions the rim is usually a little inflated, funnel-like, 

 the door resting more-or-less loosely upon the rim. In such cases 

 the door is commonly a small leaf, or leaf-portion, with just 

 enough silk to hinge it in position and form a lace-work on the 

 under side, in which the spider can fasten its claws. In open situ- 

 tions, the trap is generally level with the soil surface, in level or 

 somewhat slanting spots, and is composed of a thick lining of silk 

 below with a complete layer of soil above, more-or-less decorated 

 with moss or leaf-bits, always assimilating its surroundings. One 

 of the largest burrows examined was 27 cm. deep, 14 to iS mm. 

 diameter, with trapdoor 14x12 mm. ; lateral chamber only 6 cm. 

 down, with 7 m.m. opening and 13 mm. greatest diameter. 

 Another Yvas 28 cm. deep, 15 to 18 mm. diameter; trapdoor 25 x 16 

 mm. (unusually large) ; lateral chamber 18 cm. down with 9 mm. 

 opening and 3.5 cm. long. The one male found was in a typical 

 burrovr, with typical trapdoor, lateral chamber, and silk lining. 



No knowledge was gained concerning their feeding habits, 

 except that near dusk the spiders are found out at the surface, 

 with the trap raised just a little, enough for the hidden animal to 

 see out, evidently watching for a chance to grab some passing 

 insect. If the door is touched, the spider may jump out at the 

 stick, or other object, extended, and then hurriedly retreat 'into 

 the depths of the nest; again it may fasten its claws in the silk 

 lining of the trap and hold the door down firmly. If the door 

 is forced open, it will hastily retreat to the bottom of the tube. 



The eggs must be laid sometime in the summer, as females 

 with the abdomen much enlarged and the egg-filled ovaries show- 

 ing thru the ventral skin ha\'e been taken in March and June. 

 Females with young running about in the nest were taken in 

 September, October, and December. 



Young taken from the nest of the parent and placed in indivi- 

 dual vials, with an inch of loose moist soil, burrowed into the 

 soil, within a few hours, with few exceptions, and placed neat little 

 traps (measuring about 5x4 mm.) at the proper place. At var- 

 ious times certain of the doors were removed, new ones being 

 usually built within a few hours. One which neglected putting a 

 door to its burrow, finally did so, after being disturbed with 

 water, two months later. In general, they were sadly neglected 

 as to being supplied with food ; but once, upon removing some of
