Figure 7. — Simrad tracing of a concentration 110 fathoms deep, presumed to be a school of Engraulis 

 mordax. The recording, from left to right, is nearly continuous — the two vertical white lines were 

 caused by brief intervals when the machine was not inking the paper. The vertical black line on 

 the left is the reference mark indicating start of the tow at depth. John N. Cobb station 93.29, 

 cruise C6208.

These specimens differ in certain respects from 

 the original description of the holotype by Parr 

 (1960 : 42), but further study is necessary to eval- 

 uate these differences (R. J. Lavenberg, personal 

 communciation). The Cobb Mark-II pelagic 

 trawl took this species in relatively large numbers 

 (52 in one tow and 28 in another) and at larger 

 sizes (up to 252 mm.) than were previously re- 

 corded. 



9. PeUisolus facilis Parr. 



Figure 6D. 

 90.120, H6204 (1) 56.5 mm. 



This specimen represents an appreciable range 

 extension from the type locality south of Panama 

 given by Parr (1960 : 97) . 



10. Mirorhctus taaningi Parr. 



Figure 6D. 

 120.70, H6204, (1) 120 mm. 



The jaw morphology and mechanism in this and 

 another specimen examined are like that of all 

 other alepocephalids and most other fishes and not 

 like that described for the apparently distorted 

 holotype by Parr (1960: 30). This fish and a 

 specimen in the collection of Scripps Institution of 

 Oceanography from near Guadalupe Island ex- 

 tend the recorded range of the species from the 

 type locality in the Gulf of Panama.

 mm. 



These specimens are questionably identified, be- 

 cause slight differences suggest that they may be 

 specifically distinct from the species described 

 from off Madeira by Maul (1957: 11) (R. J. 

 Lavenberg, personal communication). This 

 species was placed in a new subgenus, Krefftia, by 

 Parr (1960:71).
