188 HIALMAR RENDAHL 



except the hindmost one are easily recognized by having their 

 tips sHghtly bilobed. The posterior part of the lateral line occu- 

 pies the 14 posterior scales on the median line, also these sca- 

 les are slightly bilobed. 



The color of the specimens preserved in alcohol is an indif- 

 ferent hght brownish. Along the middle of the sides, there is, 

 however, on the posterior half of the body, a bluish-silvery 

 longitudinal stripe. The fins are transparent, save for the mem- 

 brane between the second and third spines of the first dorsal fin, 

 which is black pigmented. 



The measurements of the type-specimen are: total length 

 (s. c.) 49, height 20, head 17,5, postocular part of head 7,6, snout 

 and interorbital space 3,7, eye 5,5, second spine of first dorsal 

 15,5, third spine of the same fin 13, second spine of the anal 

 fin 9, third spine of the same 10 mm. 



The description above refers to the largest of the three pre- 

 sent specimens. The two smaller ones of course show some 

 smaller differences according to age and size. I will state them 

 here and indicate the specimens in accordance with their length 

 as 38 and 35. Height in length 2,3 (38), 2,4 (35); head in length 

 2,6 (38), 2,7 (35). In specimen 38, the dorsal and anal spines 

 have partly been injured, in specimen 35, the relations between 

 the second anal spine and the total length is as in the type- 

 specimen. In the anal fin, the second and third spines are about 

 subequal, not fully reaching Vi of the length of the third dorsal 

 spine. The serrations of the praeorbital bone and the opercles 

 are as in the type. The development of the lateral line shows 

 the most striking differences. Unfortunately, a part of the scales 

 has been rubbed off in the small specimens; in both of them, 

 however, the lateral line makes a still more rudimentary impression 

 than in the type. In specimen 38, one can recognize traces of 

 the two parts of the lateral line; the scales, however, lack the 

 bilobed specialisation stated in the large specimen. In specimen 

 35, there are also traces of the upper-anterior portion of the
