Collett (i88o)i has shown that (in general) the number of dorsal and anal rays is 

 greater in specimens from northerly than in those from more southerly localities, and 

 notes that " the increased number of fin-rays involves a proportionate augmentation 

 in the number of scales, vertebtcP, and pores in the lateral line ". Below are given 

 the counts of fin-rays and scales for a number of specimens selected from several 

 localities :
