The study of the development of the anterior part of the vertebral column in the goldfish,Carassius auratus (L), presents an interesting problem on account of the modification associated with the presence of the Weberian ossicles. Although much descriptive and anatomical work has been done on the Weberian ossicles, the early stages of their development have been described only by Nusbaum (1881) in the carp and by Matveiev (1929) in the rudd, who are by no means wholly in agreement with regard to the method of origin. Some difference of opinion also exists with regard to the existence of separate intercalary elements in the anterior part of the vertebral column of teleosts. In this investigation of the development of the anterior vertebrae and Weberian ossicles of the goldfish it has been my endeavour to elucidate these points.
