Alepocephalus tenebrosus, Gilbert 

 Plate II, Figure 1 



Specimens from stations 5682, 5685, 5688 in 491 to 645 fathoms, and 

 two others too imperfect to be determinable with certainty from stations 

 5683 and 5694 in 630 to 640 fathoms. The above stations range from 

 approximate latitudes 28° off Pt. San Bartholome to 23° off Cape San 

 Lucas, Lower California, with the exception of the last named which is 

 farther north, approximate latitude 33°, southwest of the Santa Barbara 

 Islands,. California. 



Color, fresh, entirely black (station 5682). Five specimens, station 

 5688, pebbly bottom, head deep blue-black, body lighter. 



Alepocephalidae 

 Bajacalifornia, new genus 

 Body covered with small thin cycloid scales. Ventrals well developed. Mouth 

 moderately wide, larger than in Alepocephalus. Lower jaw strongly projecting, ending 

 in a pointed knob directed obliquely forward. Edge of jaws with a single row of small 

 teeth. Gill openings wide, membranes joined below, free from isthmus. Dorsal and 

 anal short, of about equal length, anal origin behind middle of dorsal. 



Named for the peninsula of Lower California. Based on the fol- 

 lowing new species. 



Bajacalifornia burragei, new species 



The type and only specimen (No. 8343, American Museum of Natural History) 

 collected by the 'Albatross' Expedition of 191 1 off Todos Santos Bay, Lower California, 

 station 5674, approximate latitude 31°, 590 fathoms, is 4% inches long to base of 

 caudal (which is broken). Head, 3% in length to base of caudal; depth h}{. Eye, 

 3/2 in head; maxillary, 2%; snout, 3; interorbital space, % eye. 



Mandible projecting a distance equal diameter of pupil. Origin of dorsal equi- 

 distant from base of caudal and margin of preopercle. Base of ventral equidistant 

 from base of caudal and center of eye. Origin of anal slightly behind center of dorsal. 

 Greatest depth at back of head. Eye impinging on upper outline of head. A distinct 

 ridge over each eye. Interorbital narrowly concave. Snout rather broad and rounded 

 in cross section, concave in profile. Maxillary wide, barely reaching center of eye. 

 Mandible with a pointed knob at symphasis directed forward and downward. Width 

 of snout % diameter of eye. Width of posterior end of maxillary % eye. Color uni- 

 form black. 



Dorsal, 16; anal, 13; pectoral, 17; ventral, 10 



Named for Commander G. H. Burrage, U. S. N., commanding the
