TypesHolotype: USNM 22534, an 897 mm female (W. Robinson, 13 July 1895). Paratypes: MCZ, ANSP (males and females) 
DiagnosisDIAGNOSIS (n=7). Readily distinguished from Eudryas quinquelineatus by the absence of dark mottling on the chin and throat, by the fact that the three dorsal dark stripes are fused to form a single broad band, and by the greater number of subcaudals (83-105 in quinquelineatus as compared with 110-119 in amarali). (Stuart 1938)
