PLATE 42. 
Pine Snake. Bull Snake. Carpet Snake. Horned Snake. 
Head small, scarcely distinct from body, ovoid and robust 
behind. In form obtusely conical, surface all strongly convex. 
Snout rather broadly convex, slightly depressed medianly above, 
its length about 114 in its width, and sides sloping down some- 
what abruptly. When viewed above rather narrowly convergent, 
ending in a rounded tip. Snout blunt in profile, and well pro- 
truded beyond mandible. Eye moderately small, a little high, 
and placed about midway in length of head, or over commisure 
of fifth upper labial and lowest postocular. Frontal plate sub- 
pentagonal, rather broad anteriorly with an emargination for 
inner prefrontals, and posteriorly converging to well-marked 
angle. Inner prefrontals elongated and subtriangular, or con- 
vergent posteriorly. Internasals broad, rather large, and sloping 
convexly over edges of snout above down to nasals. Prefrontals 
rather small, elongate, sloping convexly over side of snout down 
to loreal, and expanded below. Parietals large, their length about 
73 of width, convergent posteriorly with a slight median notch, 
and each with an accessory posterior small plate approximated. 
Rostral elevated above surface of snout, narrow, surface very 
convex, and reaching most of length of median internasal com- 
misure. Nostril large, in commisure of nasal plates, about mid- 
way in height of snout. Nasal plates large, anterior larger. 
Loreal small, ovoid and horizontal. Supraocular long, superior. 
Preocular large, and postoculars 3. Upper labials 8, sixth largest. 
Inferior labials 13, fifth largest. TTemporals small, graduated to 
lowest, which is largest, and 4 in first row. Scales of back more 
or less keeled medianly, though becoming more obsolete till 
smooth along sides, in 24 series across back and 270 counted from
