bastodes clavilatns, though between hxrge individuals little difference 

 can be ap])reciated in this character, as well as in the character of the 

 s\in])h\sial knob, or ihc notch in the front of the i)remaxillaries. 

 The maxillary reaches back to under the middle of the eye, or in the 

 largest specimens a little past the middle; its length is from 2.25 to 

 2.33 in the head. The eye is as long as the snout, including the pro- 

 jecting mandible; its diameter is contained from 3.25 to 3.50 in the 

 head. The interorbital width is three-fourths of the diameter of the 

 e\"e. It is less uniformly con\ex than in Sebastodes clavilatns owing 

 to the orbital ridge being a little more prominent, so that there is a 

 slight depression between the raised orbital rim and the convex middle 

 portion of the interorbital space. With this exception, and with the 

 exception that the occipital ridges are a little closer together, the 

 cranial ridges and spines are alike in the tw^o species, as well as the 

 preopercular spines. The slender gill-rakers are half the length of 

 the eye, or a little longer, and number from twenty-six to twenty-eight 

 on the lower limb of the arch. 



The scales are a little larger than in Sebastodes clavilatns, particularly 

 abo\-e the lateral line, but are otherwise similar and cover the same 

 areas. They number from forty-one to forty-five in the lateral line 

 or in the obliciue series afjove the line. The pectoral is not so narrow 

 and pointed, and does not reach so far back. The caudal peduncle 

 is wider and not so abruptly expanded at the caudal fin; its depth is 

 contained from 3.4 to 3.6 in the length of the head; the notch in the 

 caudal is not more than half as deep. The second anal spine is con- 

 i siderably longer and stouter than the third, and much stouter than in 

 Sebastodes clavilatns. It sometimes reaches almost to the tips of the 

 soft rays, but usually is somewhat shorter; its length varies from 1.6 

 to 1 .8 in the head. The anal fin is a little farther forward than in Sebas- 

 todes clavilatus. There are seven anal rays, and fifteen dorsal rays. The 

 lowest spine at the dorsal notch is from one-half to three-fifths of the 

 length of the fourth spine, which is 2.4 to 2.5 in the head or usually 

 equal in length to the anterior dorsal rays, but sometimesa little shorter. 

 In females with the abdomen swollen with eggs the ventrals do not 

 nearly reach to the vent, but they do reach to it in the males. 



The color of specimens taken in life is coppery-red with indefinite, 

 broken, greenish-brown cross-bars or blotches. Greenish bands run 

 back from the eye. Spinous dorsal dark green, with bright red towards 

 tips of spines; the outer half of the soft dorsal bright red, the base
