NOTES AND MEMORANDA. 347 



Mr. Dunn adds that the specimen forwarded to us was by no means 

 unique, as similar ones occur at Mevagissey from time to time, one of 

 which, caught in 1896, he still preserves. He concludes that the 

 deformity is caused by the fishermen in the above-mentioned way, the 

 injury to the mouth being gradually repaired, although its structure is 

 permanently modified, by the forward growth of the soft cheek tissues, 

 as already described. My observations entirely support this view of 

 the origin of the abnormality. 



There is one point to which I will draw attention in conclusion. 

 Hitherto, to the best of my knowledge, this deformity has not been 

 recorded as occurring elsewhere than on the Cornish coast. I should 

 be glad, therefore, if fishermen and sea-anglers generally would be good 

 enough to forward to the Director of this Laboratory any similarly 

 abnormal specimens of the Sea Bream which they may come across, in 

 order that the distribution of the abnormality may be recorded. It 

 would appear to be possible to make use of the facts as evidence in 

 connection with the winter movements of the fish, especially if such 

 specimens should be captured in the early part of the season. In such 

 a case the injury must have been produced in the preceding season, 

 before the winter migration. Walter Garstang.
