We report the first case of unusually frequent abnormal anatomy in Pseudacris streckeri and the first such account for anurans in the state of Texas. We found abnormal digits in 55% of 40 adult males and 26% of 23 adult females in Austin, Texas. In contrast to other studies that reported frequent abnormal limbs and cutaneous fusion, abnormalities were restricted to digits. None of 325 newly metamorphosed juveniles showed abnormal digits, indicating that the abnormalities are formed after metamorphosis, or that the cause of the abnormalities was not active during the sampling period. Abnormalities continued to be found in the adults of this population during the following 3 years.
