of the lateral line. Eyes above with green spots. Fins nearly plain 
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 has been hitherto confounded with rosaceus, from which it may be 
known at once by the green spots and the great height of the dorsal. 
SEBASTICHTHYS CONSTELLATUS sp. nov. 
Body rather robust, heavy forwards, tapering into a rather slender 
caudal peduncle. Head 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 upper jaw. A conspicuous 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: Nasal, 
preocular, supraocular, postocular, tympanic, 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, ending in a sharp spine. 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-third the diameter of the orbit, 
its edge lobed, without spines. 
Eye large, 44 in head. 
Muzzle and preorbital 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 3 + 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 
half-way up. 
Soft dorsal rather low, about equal to the spines. 
Anal with the second spine robust, curved, considerably longer than 
the third, higher than the soft rays. Caudal very slightly emarginate.
