Compared with L. vevrillii Goode & Beau, therefore, we have in L. kolthofji: 

 The bod\- is more slender, the height over the anus being 4,9—5,2 '7o of the total length (against 



5,5 — 6,2 "/,, in L. verrillii). 

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



(against 31,9—33,3 7o in L. verrillii]. 

 The head is relatively shorter, its length being 14,3— 14,8 "/o of the total length (against 19,3 |in $ 16J % 



in L. verrillii). 

 The dorsal fin begins relatively fnrther forward, its distance from the snout being 18,6—18.9% of the 



total length (against 23,2 — 2^,()'\„n\ 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 ", o in L. verrillii). 



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

 L. verrillii. 



L. kolthofji 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 S, the longitudinal diameter 

 of the eye is 2,9 °,o, the length of the pectoral 7,9" o, the distance of the dorsal fin from the snout 

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

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

 the sides.

The height over the anus is 5,1 "o 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 12,4^0 of the total length. The anterior end of
