404 REVISION OF SEBASTINJE—EIGENMANN AND BEESON. vol. xvii. 



Sehastichthys chrysomelas purpureas, Eigenmann and Eigexmann. Notes San 



Diego Biol. Lab. I, p. 8, 1879 (Cortes Bank). 

 Habitat. — San Diego to San Francisco. Abundant and variable. 



The specimens examined are from San Francisco. 



X. Genus AUCTOSPINA (Eigenmann and Beeson). 



Auctospina, Eigenmann and Beeson, Amer. Nat., July, 1893 (auricnlatus). 

 Type. — Sehastes aurieulatus, Girard. 



This g-enus is now known from two species. One of these inhabits 

 the shallow bays and generally shallow waters not frequented by other 

 species of this group. The other is as yet known from deep water only, 

 260 fathoms. 



The genus seems to us to be well characterized by the presence of 

 coronal spines, a pair of spines on the frontals anterior to the origin of 

 the parietal ridges. In auricnlatus there is a blunt knob on the fron- 

 tals between the coronal spines and the parietal ridges. 



ANALYSIS OF THE SPECIES OF AUCTOSPINA. 



a. Peritoneum black; maxillary nearly reacbiug vertical from posterior margin of 

 orbit, 2;^ in head; eye large, 3 J- in head, much longer than snout or interor- 

 bital width; interorbital with a pair of strong ridges. Preopercular spines 

 radiating; highest dorsal spine, 2i iu head; mandible scaled; scales very rough 

 ctenoid, those on breast, branchiostegal rays, and mandible rough. Uniform 

 light below, a narrow black streak along edge of spinous dorsal, the trian- 

 gular incised portion of membrane above it white Cf). Depth, 2f ; head, 2|;
