* Prof. Eobert Collett (Christiania Vidensk. Selsk. Forh., 1879, No. 1, 42), defines the chief 

 color varieties of this species as seen in Norway, as follows : 

 Var. a. assimilis, Collett: uniform light reddish gray, the dots microscopic. Christiania, 



Bukn, Sravanger, Lofoten ; scarce. 

 Var. b. stellatus, Malm: uniform light gray brown, the fins with vertical dark cross 



bands; dots larger. Christiania, Vadso, etc. Liparis stellatus, Malm, Fb'rh. Skand. 



Nat., 9, 1863, 412. 

 Var. c. subfuscus, Collett: almost uniform ground color, with dark points; light red cross 



bands on fins; body faintly marbled. Christiania, Farsund, Varanger. 

 Var. d. scorpioides, Collett: color pale, with large, irregular, dark spots. Varanger. 

 Var. e. mixtus, Collett : spotted and striped ; dark spots on fins ; along sides and on fins 



interrupted dark stripes : ring-like lines on head. Lofoten. 

 Var. f. decorus, Collett: striped and spotted; fins spotted; notable stripes on sides. 



Christiansund and Lofoten. 

 Var. g. scriptus, Collett : striped, the dark stripes larger and more conspicuous, the 



streaks of ground color fainter. Bukn, Christiania.

A.S noticed under Neoliparis montagui, these variations seem to have no taxonomic 

 value, being products of the immediate surroundings.
