The measurements used are fork length, head length, upper jaw length, snout length, length of dorsal fin base and anal fin base and the distances from the tip of snout to insertion of dorsal fin, to pectoral fin, to ventral fin and to hard margin of preopercle

The development process, from fertilized egg to spiracular formation can be divided into 26 stages, took 212. 94 hours under the water temperature of ( 20 0. 5 ) and 170. 95 hours under the natural temperature ( 21. 5 24 ). the external morphological characteristics in various stages of the embryonic development were similar to those of rana nigromaculata, but the hatching stage was later than that of rana nigromaculata and earlier than that of rana limnocharis
自受精卵期至鰓蓋完成期共分為26個時期，其發育歷程及各時期胚胎外形特徵與黑斑蛙基本相似，但孵化期比黑斑蛙推遲三個胚期而早於澤蛙，在水溫（ 20 0 . 5 ）及常溫（ 21 . 5 24 ）條件下，其胚胎發育的全時程分別為212 . 94小時和170 . 95小時。
