L. verrilUi Goode & Bean: 



Total length in mm. 



Length of head 



Distance between end of snout and anus 



Height above anus 



Distance of dorsal fin from end of snout 



Length of pectoral 



Horizontal diameter of eye 



Compared with L. verrillii Goode & Bean L. kolthoffi has: 



The body more slender, as the height above anus amounts to 



4.9 — 5.2 °/o of the total length (in L. verrillii the corresponding 



numbers are 5.5 — 6.2 %). 

 Anus situated more to the front, its distance from the end 



of the snout amounting to 27.8 — 28.4 % of the total-length 



(in L. verrillii 31.9—33.3%). 

 The head comparatively shorter, its length amounting to 14.3 — 

 14.8% of the total length {in L. verrillii \ д. д [in ? 16] %). 

 The dorsal fin starting comparatively farther to the front, as its 



distance from the end of the snout amounts to 18.6 — 18.9% 



of the total-length (in L. verrillii 23.2 — 25.9 '^/o). 

 The pectoral fins larger, as their length amounts to 10.3 — 11.3 % 



of the total-length (in L. verrillii 8.3 — 8.9 %). 

 The eyes comparatively smaller, as their horizontal diameter 



amounts to 2.5 % of the total-length (in L. verrillii 3.7 — 



4 %). 

 Moreover the dark markings form a marble-pattern in L. 

 kolthoffi^ but in L. verrillii regular transverse bands. 



L. kolthoffi is much closer related to L. sarsii Coll., from 

 which species it is however easily distinguished by its eyes 

 being comparatively a little smaller, its pectoral fins larger, and
