frequency curves (Table VII), with the two averages closely similar to one another, 

 namely 0-97 and 0-92 mm. The length ranges between 0-90 and i -05 mm. in the first 

 group and between 0-84 and 0-98 mm. in the second. The extreme range of size is be- 

 tween 0-84 and I -08 mm. Ruud (1932, p. 47) states that the length of the body in the 

 Metanauplii of £■. superba examined by him is from 0-72 to 0-82 mm. He also states that 

 the carapace of all the specimens was rather swollen, so that his larvae must have been 

 considerably smaller than any found in the present material.
