CLUPEID.E. 



The Clupeoids, which are recorded in Table XXV, have not been fully 

 determined specifically, though the material contains examples of three 

 species, Clwpea harengus L., C. sprattus L. and C. pilchardus Walb. A 

 survey of Table 2 shows a maximum frequency in numbers during May 

 and June, and the records for these two months are chiefly those of the 

 Sprat, though Herring and Pilchard are also represented. The increase 

 in numbers during September and October, after a decrease in July and 

 August, was due largely to the capture of larval Pilchards, which were 

 easily identified by the presence of an oil globule and segmented yolk. 

 The occurrence of the eggs and early stages of C. jjUchardus during a 

 considerable part of the year raises the important question (which will be 

 discussed in a later contribution) as to the periods of spawning for this 

 species.
