Iii the ninth specimen in the foregoing tahle, five of the ventrals behind the 
26th of the series are divided like subcaudals. In the umbilical region of snakes a 
tendency to division of the plates is rarely present, but complete division of the ventrals 
in the mesial line so far anteriorly is an exceptional occurrence and worthy of record.
