134 KENDALL: NEW ENGLAND SALMONS. 



Length V. — The proportion of length of ventral of the 17.6-inch Grand Lake breeding 

 male is higher than that of any length-class of lake salmon or Atlantic salmon other than 

 the parr. It correspond^ to the 6.5-inch female and the 6.4-inch male. The proportions 

 of the 14.7-inch breeding Presumpscot male, the 25.5-inch Sebago male, and the 19.3- 

 inch Grand Lake female are equal to that of the 28.3-inch breeding male Atlantic salmon, 

 which is the highest of the Atlantic salmon length-classes excepting those of the parrs. 

 In this proportion the lake salmon average somewhat higher than do the Atlantic 

 salmon which apparently is the only difference. 



Head. — The proportions of the head of the Presumpscot 12.8-inch non-breeding male, 

 the 21.9-inch non-breeding Sebago male equal only that of the 28.3-inch breeding 

 Atlantic male, which is highest of the Atlantic salmon length-classes. The proportion 

 of the 14.7-inch Presumpscot male equals that of the parrs, the three of which are aUke. 

 The proportion of the 17.6-inch breeding male of Grand Lake is three per cent higher and 

 of the Sebago 25.5-inch breeding male is four per cent higher than that of the breeding 

 male Atlantic sahnon, which is the highest of aU the length classes. 



Snout to Nape. — The proportion of snout to nape in the length classes of the 17.6- 

 inch Grand Lake male and the 25.5-uich Sebago male are equalled by no size-class of 

 Atlantic salmon, the Sebago fish being higher by two per cent than that of the 28.3- 

 inch breeding male Atlantic salmon. The proportions of the 13.2-inch Presumpscot 

 female, the 16.5-inch Sebago female, and the 19.3-inch Grand Lake female are alike and 

 not represented in the Atlantic salmon. The proportion for the 16.5-inch Sebago female 

 is one per cent higher than the 16.3-inch Atlantic female. 



Nape to D. — The proportions for the 12.8-inch Presumpscot non-breeding male, the 

 17.6-inch breeding Grand Lake male, the 21.9-inch non-breeding Sebago male, the 25.5- 

 inch Sebago breeding male, and the 18.9-inch breeding female of Sebago are all equal to 

 the proportion for the 28.3-inch male Atlantic salmon, which is the highest for the 

 Atlantic salmon, excepting that for the 6.5-inch and 8.4-inch male parrs, and which 

 are the same and of course equalled also by the above mentioned lake salmon propor- 

 tions. 



D. to Ad. — In the proportion for this dimension there appears to be a distinct dif- 

 ference between lake salmon and Atlantic salmon, for only one length-class of each has 

 a corresponding proportion, i.e., the 16.5-inch non-breeding female equals the 28.3-inch 

 breeding male Atlantic salmon, which is the lowest for the Atlantic salmon, but is higher 

 than all the other length-classes of lake salmon. The proportions for the 16.5-inch 

 female lake salmon is lower than that for the 16.3-inch female Atlantic salmon by two 

 per cent. The 12.8-inch Presumpscot male equals the 6.5-inch male parr. The 13.2-inch 

 Presumpscot female and the 14.8-inch breeding Presumpscot female equal the 6.5-inch 

 female and the 8.4-inch male parr. The 17.6-inch breeding Grand Lake male equals the 

 6.5-inch male parr. The 19.3-inch Grand Lake breeding female equals the 6.5-inch female 

 and 8.9-inch male parr. The 21.9-inch Sebago male equals the 6.5-inch male parr. The 

 18.9-inch breeding Sebago female equals the 6.5-inch female and the 8.4-inch male parr. 

 The 25.5-inch breeding Sebago male equals the 6.5-inch male parr.
