378 Part III. — Tirentidh Annual Ueport 



with an average of 40*5 mm., the next largest, belonging to the succeeding 

 series, measuring 60 mm. On 19th August, at Station III., 24 ranged 

 from 46 to 75 mm., with an average size of 51 "3 mm., or 2 inches ; on 

 22nd August nineteen, ranging from 45 to 59 mm., had an average length 

 of 52'8 mm.; the average of the tAvo combined was 51 "9 mm., or 2^^ 

 inches. At Station V., on 24th July, foui' ranged from 39 to 51 mm., 

 with an average of 43'3 mm. ; on 16th August the average was increased 

 to 52'3, the number of specimens being 31 and the size varying from 44 

 to 59 mm. On 21st August sixty-five of this series, ranging from 36 to 

 63 mm., had an average length of 54'4 mm., and the mean size of the 

 96 fishes belonging to this series for the dates mentioned was 54*8 nmi., 

 or 2yV inches. 



The next series was also well represented in most of the hauls, and 

 formed the greater bulk of the catches. In May, in 8 to 10 fathoms, 504 

 of this series were taken, the sexes of which were not determined ; the 

 combined group gave an average of 87" 1 mm., or Scinches, and ranged 

 from 57 to 123 mm. On 20th June this series was imperfectly 

 represented, the smaller fishes being absent, and the twenty specimens 

 obtained varied from 104 to about 135 mm., giving an average of 

 113"5, which is too high. On 24th July 278 of this series ranged from 

 83 to 135 mm., with an average of 112-1 mm., or 4^^ inches, and showing 

 an increment of growth from 9th to 16th May of 25 mm., or 1 inch. 

 On 19th August this series comprised 300 long rough dabs, of which 207, 

 ranging from 100 to 146 mm., were females, with an average size of 

 122'2 mm., (4|-| inches), and 93 males, from 94 to 129 mm., and having 

 an average length of 112'4 mm. The mean length of the series combined 

 was 119"1, or 4|i inches. On 22nd August the series was represented 

 by 170 females and 90 males, the former varying in length from 88 to 

 146 mm., and with a mean length of 122-9 mm., while the males ranged 

 from 97 to 140 mm., and had a mean size of 116-9 mm. Combining the 

 hauls in August the series is represented by 560 fishes, the females 

 numbering 377, ranging from 88 to 146 mm., and having a mean length 

 of 122-5 mm., or 4J-| inches; 183 males varied from 94 to 140 mm., and 

 had an average size of 114-6 mm., or 4| inches. The mean length of 

 the combined sexes was 120-0 mm., or 4| inches, showing an apparent 

 mean growth of 7-9 mm. during the twenty-eight days fiom the date of 

 the July haul, and 32-9 mm. in the 101 days from the hauls in May. 



At the outer station, in from 20 to 30 fathoms, this series was 

 represented in the haul of 10th May by 565 specimens, ranging from 60 

 to 103 mm., and having an average size of 83-4 mm., or Scinches; the 

 mean size was thus 3*7 mm. under that of those taken at Station III. 

 On 24th July the average of the series was 116-9 mm., the number of 

 specimens being 334, and the range from 95 to 142 mm. On 16th 

 August the average of the group was 124*6 mm. (4g inches), the number 

 of fishes being 326 ; of these the females, numbei'ing 145, ranged from 

 110 to 147 mm., with an average length of 128-7 mm., and the males, 

 which numbered 181, ranged from 106 to 136 mm., and had an average 

 size of 121-3 mm. On 2l8t August the average size of 204 females 

 was 129-0 mm., and the range from 101 to 148 mm., while the mean 

 length of the males, 243 in number, was 122-8, and the range in size 

 from 106 to 141 mm. The combined August hauls for this series gave 

 an average for the 349 females of 128-9 mm., or Syly inches, and for the 

 424 males of 122-1 mm., or 4i| inches, while the average of the combined 

 sexes was 125-2 mm. (4J-| inches), and that for the group as determined 

 by the curve — including twenty-one males of the next series — was 

 125*7 mm. These averages are higher than those for the corresponding 

 series in August at the inner station by 6-4, 7'5, and 5-2 mm.
