Table 1. Condensed tabulation of specimens examined

Arranged in length groups of 10 mm. (length decades).

Table 1 shows that there is considerable variation in the relative frequency of the sexes in each of the length decades and also that there is a greater number of females than males (145 to 84) in the period between 14 and 50 mm. length. This variation in the different groups would indicate that as yet a sufficient number of embryos has not been examined to permit definite deductions concerning the sex-ratio at this period of embryonic life. Conclusions, therefore, will have to be deferred until much more extensive data have been accumulated.
