The head is of similar form as in L. seminudus, but seems to be less broad-snouted. The 



eyes seem relatively a little smaller, their longitudinal diameter being 3,3% of the total length (against 

 3,7% in the above specimen of A. seminudus), and the flap of the gill-cover is not bent upwards. 

 The number of teeth is somewhat less than in L. seminudus ; on the intermaxillary I have counted 

 15 in series, 15 on the palatines, 5 on the vomer, and on the mandible 15 in series (cf. p. 78). 



The dorsal fin begins at a distance from the snout, which is equal to 30",, of the total 

 length. The number of rays in the unpaired fins falls within that in /.. seminudus. The pectorals, 

 on the other hand, show a verv important difference, being of a much greater size, their length 

 being 16, S " ,, of the total length; in none of the [8 specimens of L. seminudus does the length 

 of the pectorals exceed 11,8% of the total length. 



The scales extend further forward than in the most scaled specimen of L.seminudus, namely 

 to a point under the anterior end of the dorsal fin, but at the same time both the belly and anterior 

 portion of the back are naked. 



The colouration agrees on the whole with that in the banded forms of /.. seminudus; that 

 the dark bands are rather indistinct (except on the dorsal fin) comes probably from the advanced size 

 of the specimen. 



The differences mentioned, especially the less slender form of the body, and the large pectorals, 

 seem to me so important, that I., littkcuii Coll. ought to be held distinct from L. seminudus Reinh. 



(Later. L. lutkenii presents even greater resemblance to I., rassi Malmgr., whose appearance 

 in the adult condition is now known. Of important differences I can only mention, that in I., rossi 

 the pectoral fins are shorter (their length being 13,1-13,6",, of the total length) and contain fewer 

 ravs, namely 17—20. All the same, I think it best to keep these forms separate so Ion- as transitional 

 forms are not found).

The height over the anus amounts to 11,3—14,2 ° ,, of the total length. The 

 length of the head in males is 25,1 26,5 " ',,, in females 22,4 24,4 " ,, and the longi- 

 tudinal diameter of the eye 4—2,7 " of the total length. The distance between the 

 snout and the anus in males is 46,7 40,7" ,, of the total length, in females 46,2 47,4 

 The length of the pectoral is 13- 14,2 " ,. of the total length. Young specimens have 

 7 9 dark cross-bands on the trunk and tail, which (all or essentially only the 

 foremost) form network markings in the older; a light band across over the neck
