ADDENDUM. 
Since the present Memoir went to press, C. Tate Regan, M. A., of the British Museum, 
has published “The Systematic Arrangement of the Fishes of the Family Salmonidae.” ‘ 
The classification of the Salmonidae, according to Regan’s interpretation of skeletal 
characters, consists of the two subfamilies, Salmoninae and Coregoninae, as in the present 
Memoir. 
According to Regan’s arrangement Salmoninae includes the genera Salmo, Salvelinus, 
Hucho, and Brachymystax, the latter being closely related to Hucho. Coregoninae comprises 
Stenodus, Coregonus, Phylogephyra, and Thymallus. 
It is to be noted that Plecoglossus is omitted from the classification and Brachymystax 
is included in Salmoninae. Oncorhynchus is relegated to Salmo and Thymallus, which Gill 
considers as constituting a distinct family (Thymallidae) , is included without stated reasons 
in Coregoninae. Regan’s disposition of Oncorhynchus seems to be based solely upon a few 
anal fin rays of “Salmo (Oncorhynchus) masou.” 
The distinguishing characteristics of Salmoninae and Coregoninae are stated to consist 
mainly of the arrangement of the parietals which he says do not meet in the middle line in the 
former and do so meet in the latter. 
According to Regan the genus Salvelinus comprises three groups essentially conforming 
to the arrangement in the present Memoir, thus: 
“1. S. alpinus group. — Head of vomer with posterior process but little developed. 
Basi-branchial teeth uniserial. No dark spots or markings. Circumpolar. 
“2. S. fontinalis group. — Head of vomer with a well-developed posterior process. 
Basi-branchial teeth absent. Blackish or dark olivaceous spots or markings on back, dorsal, 
and caudal fins. N. America. 
“3. S. namaycush group. — Head of vomer with a long posterior process. Basi-bran- 
chial teeth in a long patch. N. America.” 
After giving diagrams showing the arrangement of the vomerine teeth in Salvelinus perisii, 
S. fontinalis, and S. namaycush, it is stated that S. fontinalis is so exactly intermediate between 
the typical charr and S. namaycush in the form and dentition of the vomer that it is thought 
best to give up the genus Cristivomer. 
Attention should be called to the fact that in the S. alpinus group the basi-branchial 
teeth are not invariably uniserial, but vary from elongate patches to few or no teeth at all. 
This seems to be individual variation rather than a group or specific character.
