Another from the same station, 29 inches long, has whip-like caudal 

 region and very narrow caudal equaling % snout. One from station 

 5685, in 645 fathoms, 23K inches long, has wide and heavy caudal and 

 much the broadest caudal region, caudal l}{ times snout. 



Serrivomer sector Garman 

 A specimen nineteen inches long from station 5674 ; approximate 

 latitude 31°, off Todos Santos Bay,. 590 fathoms, and a second somewhat 

 imperfect one from station 5683 ; off Cape San Lucas, approximate 

 latitude 23°, 630 fathoms, are obviously this species of Garman, which, as 

 Gilbert suggests ('Deep Sea Fishes of the Hawaiian Islands/ p. 586), 

 may be identical with S. beani of the Atlantic. 



Nemichthys fronto Garman 

 One from station 5685 southwest of Balenas Bay, approximate 

 latitude 26° in 284 fathoms, and one from station 5687 off Pt. San 

 Bartholome, approximate latitude 28°, in 480 fathoms. 



Cyema atrum Giinther 



One specimen from station 5691, 868 fathoms (approximate latitude 

 31°, off Todos Santos Bay, Lower California). 



Color, fresh, entirely black. 



This is the first record of the occurrence of this genus in eastern 

 Pacific waters. 



Plectromus [Melamphses] maxillaris Garman 

 A specimen from station 5695 (near the Santa Barbara Islands, 

 California, approximate latitude 34°) in 534 fathoms, and one from 

 station 5692 (west of San Diego, California, approximate latitude 31°) 

 in 1076 fathoms. A third specimen of this genus from station 5675 is too 

 mutilated for specific determination. 

 Color, fresh, black (station 5692) .
