The preparation of the normal tables and plates on Nedurus was begun several years ago by Professor C. O. Whitman but on account of unavoidable circumstances the work was delayed. It was later taken up by Professor Eycleshymer upon the suggestion of both Professor Whitman and Professor Keibel. While Professor Whitman has not directly participated in the later work, he has furnished the senior author with material and Information without which it would have been impossible to complete the work. In the completion of the work the senior author has been fortunate in having the able Cooperation of Professor James M. Wilson. | The preparation of the normal tables and plates on Nedurus was begun several years ago by Professor C. O. Whitman but on account of unavoidable circumstances the work was delayed.

Preface
The preparation of the normal tables and plates on Nedurus was begun several years ago by Professor C. O. Whitman but on account of unavoidable circumstances the work was delayed. It was later taken up by Professor Eycleshymer upon the suggestion of both Professor Whitman and Professor Keibel. While Professor Whitman has not directly participated in the later work, he has furnished the senior author with material and Information without which it would have been impossible to complete the work. In the completion of the work the senior author has been fortunate in having the able Cooperation of Professor James M. Wilson.
Table of Contents
Description of lllustrations
The series of eggs, embryos and larvae of Necturus, from which the following descriptions and the appended illustrations were made, were collected May I5th, 1903 and kept at a water temperature of 17o — 18o C. The illustrations are copied from the original water colored pictures which were made by Mr. Leonard H. Wilder, under the direction of the senior author. It should be emphasized that the ages, measurements and illustrations are all made from the living objects.
