of the lateral line. Eyes above with green spots. Fins nearly j)lam 

 red ; the dorsal spotted with olive. 



This species is known to us from numerous specimens obtained in the 

 San Francisco market, taken in deep water at Monterey. It is not rare, 

 but it lias been hitherto confouilded with rosaceiis, from which it may be 

 known at once by the green spots and the great height of the dorsal. 



Sebastichthts constellatus sp. nov. 



Body rather robust, heavy forwards, tapering into a rather slender 

 caudal peduncle. Ilead rather pointed in profile, the slope nearly- 

 straight from the tip of the snout to the base of the dorsal. 



Mouth large, oblique, the lower jaw slightly projecting beyond the 

 emarginated tip of the ui)per jaw. A consx)icuous knob just beyond the 

 symphysis of the lower jaw. 



Maxillary very broad, extending to beyond the line of the pupil, its 

 middle part with many small scales; premaxillary in front just below 

 the level of the eye. 



Ridges on top of the head well developed, rather high and narrow, 

 ending in moderate spines. The following pairs are present: Nasaly 

 preocular, supraocular^ postocular^ fytnpanic, and occipital. The inter- 

 orbital area has two prominent ridges covered by the scales, and not 

 ending in spines. Behind these is a deep concavity. The nasal spines 

 are bluntish, the preocular sharp, the supraocular ridge rather short, 

 the postocular and tympanic similar to each other. The occipital ridge 

 is long, curved, enduig in a sharp sjune. Two suprascapular spines. 

 Preopercle with its first and third spines triangular, bluntish, the sec- 

 ond long and sharp, the fourth and fifth reduced to bluntish prominences. 

 Opercle with two strong spines above. Slight spines on the subopercle 

 and interopercle. 



Preorbital wide, its neck about one-thiid the diameter of the orbit, 

 its edge lobed, without spines. 



Eye large, 4.^ in head. 



]\lnzzle and ])reorbital scaled to the tip of the snout more completely 

 than in other species, mandible scaly. 



Gill-rakers short, very thick, compressed, clavate, with a'tuft of spine- 

 like teeth at tip, the longest of them about one-fifth the diameter of the 

 eye, their number o -{- 24 free ones, besides rudiments. Scales strongly 

 ctenoid, the accessory scales largely developed ; 53 transverse series. 



Dorsal spines rather strong, rather low, the fourth the longest, a little 

 more than one-third the length of the head. Twelfth spine rather short, 

 shorter than the first, its membrane joining the thirteenth spine about 

 lialf-way up. 



Soft dorsal rather low, about equal to the spines. 



Anal with the second siniie robust, curved, considerably longer than 

 the third, higher thiui the soft rays. Caudal very slightly emarginate.
