1895.] Zoology. 677 
Gastrosteges 131; anal 1-1; urosteges 82. The lateral black spots 
extend as far as the tail. The dorsal stripes are connected by a trans- 
verse lighter brown shade for a short distance in advance of the vent. 
Belly black with a median series of semidiscoid yellow spots; gastros- 
teges with yellow extremities for the anterior two-thirds of the length 
of the body. The median neck stripes touch on the nape, and after 
enclosing a pale space unite on the parietal plates. Muzzle brown, the 
labials with blackish shades. Lower labials, genials and gulars with 
yellow spots. Indistinct parietal paired spots. Total length 378 mm. ; 
of tail 98 mm. 
Two specimens in my private collection from Volusia, Florida. 
In this form the striping which appears on the neck of the form com- 
presstcauda is extended the entire length. It bears thus a partial re- 
semblance to the Natriz clarkii, which is not far removed in affinity 
from the N. compressicauda. The form next described (N. fasciata 
pictiventris) connects the latter with the N. fasciata. 
The subspecies teniata may be synoptically compared with the 
typical compressicauda as follows: 
Scales in 21 rows; four series of longitudinal spots above, those of 
the median pair forming two longitudinal stripes on the greater part of 
the length ; the laterals forming stripes on the neck only; 
N. c. teniata. 
Scales in 21 rows; numerous dark cross-bands which are resolved 
into three rows of spots just anterior to the tail, and four longitudinal 
stripes on the neck ; N. c. compressicauda. 
NATRIX FASCIATA PICTIVENTRIS Cope.—Brown transverse bands 
numerous, separated by short intervals and extending to the belly 
throughout the length. Gastrosteges narrowly margined at the base 
with brown, the margins turning at or before reaching the ends of the 
gastrosteges and uniting so as to enclose transverse yellowish spots, 
which may cover a part only or the whole of the gastrostege, but which 
are always wider than those seen in N. compressicauda. Sides of head 
light brown, generally with a black post-ocular band; top of head 
black. Scales in 25 rows; in one specimen (No. 19,798) in 27 rows. 
No. 5,473 : 25; 8:125; 45:580 mm.; 120 mm.; (tail injured). 
No. 19,999 : 25; 8:124; 86:550 mm.; 162mm. 
In some specimens (No. 13,729) the transverse bands are very distinct 
as in young individuals; in Nos. 19,798 and 11,444, they are connected 
by the same color along the median dorsal line. 
This subspecies is restricted to Florida, and it approaches the J. 
compressicauda in the coloration of the belly. The following specimens 
are contained in the U.S. National Museum.
