32 SMITT, ON THE GENUS LYCODES. 



N:o R. 16. Spitzberg, Ice-firth, Coal-bay: depth 100 m.; rocky bottom; 

 June U) — 20, 1900; KOLTHOFF-expeditiou. 



Dark (reddish-blue) variety, with narrow white crossmarks. 

 Nucbal white crossband incompletely 4-partite. Caudal dark cross- 

 marks G (7, if the dark tip of the tail-fin be counted); anal 

 opening below the front part of the first. Scalcs thin, from the 

 first to the fifth dark caudal crossmarks. Length of intermaxillar 

 series of teeth 6.i mm., of palatiue 6.7 mm. 



Adn. Vd % very fricfidus-Wke, hut lateral lines median and 

 dorsal. Cfr. N:o R. 19, below. 



N:o R. 17. Same locality as N:o V. 13. 



Rather light variety, with narrow white crossmarks but light 

 interiör of the dark ones. Nuchal light crossband undivided. 

 Caudal dark crossmarks 6, besides a dark spöt on the tip of 

 the tail, united with the last dark crossband in the white-edged 

 anal fin. Tip of tail-fin white. Belly light livid. Anal opening 

 below the interspace between the second abdominal and the first 

 caudal saddle-marks. Scales of seminudus. Length of the inter- 

 maxillar series of teeth lO.e mm., of the palatine 9.2 mm. 



X:o R. 18. Same locality as N:o R. 14. 



Very similar to N:o R. 14, but caudal dark crossmarks 6. 

 The white-edged anal lin reddish livid. White nuchal crossband 

 as N:o R. 14. Scales as semimidus. Length of intermaxillar 

 series of teeth 10.6 mm., of palatine 9.6 mm. 



N:o R. 19. Sibiria, Chatanga-bay; specimen figured in Smitt, Scand. 

 Fisk, ed. 2, p. 612. 



Length of the intermaxillar series of teeth 8 mm., of the 

 palatine 11.7 mm. This specimen together with N:o R. 16, above, 

 may perhaps be marked as a separate form, characterized by 

 short head (b; b^; &<,), rather forward advanced veutral fins 

 (r; ?'j) and long abdoraen (tr); although it seems to be the most 

 natural to hold them as merely iudividual variations. 



N:o R. 20. Same locality as N:o R. 14. 



Colour mostly as N:o R. 18, livid and reddish, the three 

 foremost (two abdominal and one caudal) white interspaces being 

 saddle-marks, the four hindmost (the white tip of the tail-fin 

 inclusive) being crossbands, but the last of these having its lower 

 part dusky and united with the dark colour of the anal fin. 

 Form of the tail with fins acute, dagger-like. Caudal dark cross- 

 bands 5 (or 6, if the dusky, lower part of the tail-fin be counted). 

 Anal opening below the usual interspace. Scales as seminudus. 

 Median lateral line most conspicuous, dorsal and ventral lines 

 thin and irregular. Length of intermaxillar series of teeth 11.9 

 mm., of palatine 12 mm. 



X:o R. 21. Greenland; 74°52'n.; 17°16'w.; depth 350 m.; mud 

 with sand and pebbles; July 4, 1899; NATHORST-expedition. 



Colour as preceding, but more uniformly red on the body. 

 Form of the tail as preceding. Caudal dark crossmarks 7, the 

 dark tip of the tail-fin inclusive. Scaly covering as seminudus,
