less than an orbital diameter; the soft rays 3 in the head. 

 Anal spines graduated, the second not much more than 

 half the length of the soft rays. 



Peritoneum black. 



Body scarlet, shading into madder brown or blackish- 

 red above lateral line. Fins vermilion, the first dorsal with 

 its membranes narrowly black edged. All other fins more 

 or less black on posterior half, the caudal most so. Head 

 vermilion, tinged with black. Inside of mouth and gill 

 cavity almost wholly black. Upper posterior portion of 

 gill membranes black. A black bar above opercle. 



16. Sebastodes eos sp. nov. 



A single specimen, .54 m., was taken off Point Loma 

 in 100 fathoms, November 14, 1889. Many others have 

 since been observed. 



This species is evidently closely related to vS". chlorostic- 

 ins and rJiodocJiloris. It reaches a much larger size than 

 either of those species has been known to attain. The 

 scaly mandible serves at once to distinguish it from chlo- 

 rostictus, while this character and the short second anal 

 spine distinguish it from rhodochloris. 



Head 2^^, (3-33^ in the total length); depth 3 (3>^- 

 334 ) ; D. XIII, i3>^ ; A. Ill, 6% ; lat. 1. 37. 



Oblong. Lower jaw included, its symphyseal knob 

 strong. Maxillary reaching beyond eye, 2 in the head. 

 Orbit I in snout, little more than four times in head, 

 greater than interorbital width. 



Interorbital deeply concave, grooved medially, 55^ in 

 head. 



Cranial ridges very high and narrow, ending in promi- 

 nent spines; preocular, supraocular and tympanic spines 

 directed outward and backward ; postocular upward and 

 backward. Occipital ridges in largest specimens 6 mm.
