Another specimen, also termed Scurf or Gochivies, was sent in April the same year, from Turcebridge- on-the-Tees : it also was a female, 16 inches long, and had recently spawned, twenty-three full-sized eggs still remaining in the abdominal cavity. Length of head 6j in the total length (see figure 31) : it had 52 csecal appendages. A third example from the same locality was a male, 18 inches long, with a small hook at the end of its lower jaw : the tail fin was slightly concave : ceecal appendages 52, and the milt well forward. All were of the general colours of salmon-trout, and the black spots extended in from one to three irregular rows below the lateral-line. bluish bands, with an orange-coloured spot placed between each " (p. 295). Mr. Shaw (1843) gave figures in tbe Transactioiis of the Boyal Society of Edinburgh of young Salmo salar, S. trutta, and S. fario, showing fourteen in the salmon, twelve in tbe sea trout, and thirteen or fourteen, some of wbiob were broken up in tbe middle, in the fresh-water trout. He also remarked, with reference to tbe young salmon-trout, that " on comparing them with tbe common trout, tbe resemblance is very striking, the general outline of tbe fish being less elegant than that of the young salmon or par, the external markings being also more peculiarly those of the trout s
