 * Maxillarj' to below anterior part or middle of eye, 2 i to 2 1 in 

 head ; lower limb of praeoperculum J or less than i as long 

 as head . . . . . . . .21. scapha. 



** Maxillary nearly to below middle of eye (in an example of 156 

 mm.), 2\ in head ; lower limb of praeoperculum rather 

 more than J as long as head . . . . .22. boops. 



2. About 110 scales in lateral line ; width of curve of lateral line 1% 

 in head ; upper profile of head markedly convex above and behind 

 eyes ; dorsal 106, anal 84 .... 23. microphthalmiis. 



B. Eyes separated by a concave space, its width J to J eye ; gill-rakers 

 palmate (short, strongly spinulate), about as broad as long ; 45 to 50 

 scales in lateral line ....... 24. intertnediiis . 



The genus Arnoglossus still remains a somewhat heterogeneous group, but I am 

 imable to find any valid reasons for its further subdivision. Apart from the two species 

 placed at the end of the genus, microphthalmiis and intermedins, which might perhaps 

 be regarded as representing distinct genera, the species seem to form a natural group. 

 Those species with canine teeth anteriorly in the jaws should perhaps rank as a 

 subgenus, for which the name Anticithams is available.
