THE CAPELIN OF THE NORTH PACIFIC — SCHULTZ 17 



Table 2. — Counts made on Mallotus /rom the North Pacific and the North Allantic^ 



1 The figures for each character show in the first line the minimum and the maximum count or measure- 

 ment, and in parentheses the number of specimens counted or measured; in the second line the mean and 

 probable error of the mean are given. The measurements are expressed as hundredths of the standard 

 length. The last two rays of the dorsal and anal fins, often branching from a common base, were counted 

 as one ray. 



' These specimens from Newfoundland were obtained through the kindness of Dr. Harold Thompson. 



« Data from Mori (1930). 



« Data from Pallas (1831). 



» The number of scales in the lateral line, counted, indicates the number of oblique rows from upper edge 

 of gill opening along the side of the body to the base of the rays of the caudal fln. 



Tamezo Mori (1930, p. 5) described as new Mallotus elongatus from 

 the Tunien River mouth at Keiko, Korea. Since his description is 

 abbreviated and apparently standard measurements and terminology 

 were not used, few comparisons can be made. He says: "This speci- 

 men is closely related to M. villosus Cuvier, differing from it in having 

 slenderer body and very minute scales without larger scales along 

 lateral line." Obviously Mori did not linow that only the males of 

 Mallotus have the enlarged or villous scales along the lateral line. He 

 did not give a scale count for his young female, 93 mm in total length. 

 The slender body was given by Mori as "depth 8.2" in bodj^ length. 

 There is no indication anywhere in his paper as to what "body length" 

 means. However, if "body length" is the same as total length, then 

 the depth of the body is 11.3 mm, or 12 percent of the total length. It 

 was found that the length of the caudal fin rays of Mallotus, in both 

 the Atlantic and Pacific, averages about 12 mm on specimens having
