1 More than 130 primary annuli, with secondary grooves restricted to the posteriormost part of the body, not on the anteriormost 100 primaries ................................. battersbyi

­ May have fewer than 130 primary annuli, with secondary grooves on more than the posteriormost part of the body, beginning anterior to the 100th primary annulus ......... ............................................................................................................ maharashtraensis
