Congenital anomalies of the upper digestive tract are not as infrequent as is generally supposed. Plass1 found 204 references in the literature and was able to verify 137 cases from the original articles. Besides these he found thirteen cases which he could not verify on account of incorrect references or inaccessibility of the original article. He does not include any references later than 1917. and since that date several cases have been reported. Cautley,2 Apfel,3 Crowdy4 and Huntington5 have each described one case, while Brenneman6 reported four new cases. In a discussion of Griffith's paper read before the American Pediatric Society in 1908, Dr. Putnam of Boston reported a case which has escaped notice.
Cautley's article contains a large number of references and in order to bring the literature up to date, I have appended to the references quoted in this paper a list
