Body rather deep, back arched, the anterior profile stiff and nearly straight, the 

 top of head broad and flattish. Interorbital space very broad, with a frontal ridge on 

 each side halfway between the median line and the orbital rim, on either side of which 

 the surface is somewhat concave, most concave along median line. Nasal spine sharp. 

 Preocular spine short and sharp. Supraocular ridge low, its spine inconspicuous but 

 present; postocular similar, but larger; tympanic similar, but still larger. Frontal 

 ridge on either side naked, without spine, but with a short, sharp coronal spine behind 

 it and continuous Avith it under the scales. Occipital ridge sharp, ending in a low 

 spine and sometimes one or two spines on its surface, a low cross-furrow separating 

 it from the short, sharp nuchal spine. A sharj) spine on the orbital rim under the eye 



' A related species, Sebastodes caurinus, was described by Kichardson from specimens taken at 

 Sitka. It had been since Eichardson's time uncertain for which species this description was intended. 

 Ou oar return from Bering Sea in 1896 considerable collections were made by the revenue cutter Bush, 

 under our direction, at Sitka, and Eichardson's species was found in abundance. Fortunately it is the 

 same one for which we had in 1880 adopted provisionally the name caurinus. 



We ijresent herewith (Plate XLIX) a figure of a specimeu taken just south of the village of 

 Sitka, the original locality of Eichardson's collection.
