(labb, collector) (tio-s. 17-19) is colored like the Veneznelaiv specimen 
so far as the underside is concerned, the bars on neck and ))ody nuni- 
berino-25 and the rino-s on tail 13, but the dark bars and rings through- 
out are broadtM" than the light interspaces, which are not regularly 
spotted with black; the black l)ars anteriorly often alternate and 
coalesce ])roadly on the median line. The scale formula differs also 
considerably from those mentioned above, being as follows: Scale 
rows, 10; ventrals, 200; anal, 1; suV)caudals, 90/90.
