 L. Stejueger. D. XIX, 24; A. 25. L. lat. 93 (87 pores). A young 

 specimen, 54 mm. long. 



This specimen shows a most remarkable abnormality in the develop- 

 ment of the lateral lines. The upper line on each side extends to the 

 middle of the soft dorsal; the second line on the left side does not 

 quite reach to below the end of the soft dorsal, while on the right 

 side the corresponding line extends to tlie caudal; on the left side the 

 line appears to start from a point nearly above the end of the ventral 

 and extends upward and backward to about opposite the ninth ray of 

 the anal; there is no corresponding line on the right side. The two 

 lines running along the base of the anal, and extending to the caudal, 

 converge in the usual way just behind the ventrals, and ai-e continued 

 forward in a single line to the root of the ventrals. 



Gill membranes united very narrowly to the isthmus.

No. 33SG8, U.S.N.M. (1950). Bering Island, March 13, 1883, L. Stej- 

 neger. Length of specimen, 120 mm.; D. XXII, 22; A. 23. 



The upper lateral line extends to below the end of the second dor- 

 sal; the second line to the upper edge of the caudal; the third to the 

 middle of the caudal base; the fourth starts from the throat, i^asses 

 close to the root of the ventral, and is continued backward to a little 

 beyond the middle of the anal. The two lines running along the anal 

 base to the tail converge about at the middle of the length of the ven- 

 trals, and are continued forward on the ridge of the abdomen almost 

 to the isthmus. There is no trace of the branch characteristic of H. 

 ordinatus, which begins a little in advance of the ventral origin and 

 extends upward and backward to a point below the middle of the pec- 

 toral and sometimes farther back.
