4, Dromicus omiltemanus, sp. n. (Tab. XL. fig. B.) 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Scales smooth, in seventeen rows, without pit; body and tail moderately slender, the 
latter not quite one-third of the total length; eye of moderate size. Anterior frontals 
about one-third of the posterior ; vertical longer than the snout, and not much shorter 
than the occipitals, which are rounded behind ; loreal square; one preorbital reaching 
to the upper surface of the head, but not in contact with the vertical; two postoculars ; 
eight upper labials, the fourth and fifth entering the orbit; a minute portion of the third 
labial is separated, forming a rudimentary inferior preocular. Temporals 1+2+2; 
posterior chin-shields a little longer than anterior. Ventrals 154; anal divided; sub- 
caudals 94. Upper parts olive-brown, bordered on each side by a well-defined yellowish 
line, which starts from the upper postocular, running along the fifth outer series of 
scales, and is lost nearly at the extremity of the tail. ‘This yellowish line is accompanied 
by an olive-black band, two scales broad, which again is bordered by a yellowish line 
much more indistinct than the one described; the lowermost two series of scales are 
pinkish grey. Lower parts whitish, each ventral scute with a black dot on either side. 
Total length 153 inches, of which the tail takes 5 inches. Dentition distinctly 
diacranterian.
