Compared with L. verrillii Goode & Bean, therefore, we have in L. kolthoffi: 

 The body is more slender, the height over the anus being 4,9—5,2% of the total length (against 



5,5 — 6,2 % m L. verrillii). 

 The anus lies further forward, its distance from the snout being 27,8—28,4% of the total length 



(against 31,9—33,3 % in L. verrillii). 

 The head is relatively shorter, its length being 14,3—14,8% of the total length (against 19,3 [in % 16J % 



in L. verrillii). 

 The dorsal fin begins relatively further forward, its distance from the snout being 18,6—18,9% of the 



total length (against 23,2 — 25,9 o in L. verrillii). 

 The pectorals are larger, their length being 10,3—11,3% of the total length (against 8,3— 8,9 % in 



L. verrillii]. 

 The eyes are relatively smaller, their longitudinal diameter being 2,5 % of the total length (against 



3,7 — 4 % in L. verrillii). 



In addition, the dark colouration is marbled in L. kolthoffi, but in regular cross-bands in 

 L. verrillii. 



L. kolthoffi stands much nearer to L. sarsii Coll., from which however it can be easily 

 distinguished in that the eyes are relatively a little smaller, that the pectorals are larger, and that 

 the dorsal fin begins further forward; thus in a 140 mm. long L. sarsii $, the longitudinal diameter 

 of the eye is 2,9%, the length of the pectoral 7,9%, the distance of the dorsal fin from the snout 

 22,2% of the total length. In addition, the colouration is quite different; the present species is 

 strongly spotted, whilst adult L. sarsii are more uniform, with only indistinct shadings down on 

 the sides.

The height over the anus is 5,1 % of the total length. The head tolerably 

 broad, the body almost round, the tail gradually compressed and losing very slowly 

 in height. The length of the head is 12,4% of the total length. The anterior end of
