24 Trans. Acad. Sci. of St. Lows 
(1919) published the record of a specimen feigning death 
for over twenty-five consecutive minutes. Blanchard 
(1922) found these creatures to be very common about 
rail fences, trees, fallen logs and stumps, and in fields 
or openings in woods. In escaping a pursuer they were 
seen in no case to run on the ground. The same author 
(1925) collected a specimen on an oak tree at Twin 
Caves, Indiana. Taylor (unpublished) stated that ‘‘ They 
are often seen about roadsides in very dry or rocky 
places.”’ 
Several authors have given details which bear upon 
the life history of the pine lizard. Hay (1892) wrote 
that ‘‘The eggs are said to be laid in the sand, probably 
in little groups. They are deposited about June 1, and 
are hatched about July 10. The eggs are long ‘and 
narrow and are covered with a tough coat, and are with- 
out any caleareous material. When laid they are aban- 
doned to their fate, but the young are treated with the 
utmost tenderness by adults.’? Hay (1902) stated that 
‘‘Higes are laid early in the summer and hatch in July. 
By the latter part of August the young begin to shift 
for themselves and leave the company of the adults.’’ 
Ditmars (1915) found that eggs may be hatched by plac- 
ing them in moderately damp, not soggy, sphagnum 
moss, and keeping them at ordinary room temperature 
where their period of incubation is from six to eight 
weeks. Dunn (1915) stated that ‘‘A female caught on 
May 10, 1914, at Marlton, New Jersey, was killed and 
dissected on June 7. She had ten large eggs in her 
oviducts. My earliest record for young is July 29 (Nel- 
son County, Virginia).’? Hyde (1923) reported April 
19, 1923, as a copulation date for the subspecies in Vir- 
ginia. Speck (1924) recorded the attempted coition of 
a male of S. undulatus undulatus from New Jersey upon
