The Smooth Sculpin, or Cabezon, Leptocottus armatus (Girard), 

 (Pig. 70) is abundant everywhere throughout the Sound region. The 

 skin is smooth and the head is oblong. No cirri are developed. The 

 preopercular spine is strong, with two or three points hooked upwards. 

 The dorsal fins are separate. It attains a length of 12 inches. 



The Marbled Sculpin, Scorpaenichthys marmoratus (Girard), is 

 the largest of our cottoid fishes since it attains a length of 30 inches 

 and a weight of 20 to 25 pounds. It is used for food but the fiesh is 

 coarse. Vhe skin is smooth and the ventral fin has one spine and five 

 rays. 



The Round-headed Sculpin, Blennicottus gloMceps (Girard), is a 

 species with a perfectly smooth skin lacking both scales and prickles. 

 The preopercular spine is short and blunt with the point turned up- 

 wards. The snout is very blunt. It reaches a size of 4 to 7 inches. 



The Moss-dwelling Sculpin, Oxycottiis emhryum (Jordan and Gil- 

 bert), (Pig. 73) is a small species found living among the rocks and 

 seaweeds along the shore. In its structure it is very similar to the 

 following species, the main difference being in the form of the spine 

 on the preoperculum. In Oxycottus it is simple while in Oligocoitus 

 it is forked. This species varies greatly in color, ranging from green 

 to maroon. It is less than three Inches in length and is quite rare. 



The Johnny or Tide-pool Sculpin, OUgocottus maculosus (Girard), 

 (Pig. 72) exists in countless numbers along our shores, and every pool 

 left by the retreating tide has its quota. It is one of our smallest 

 species, seldom measuring as much as three inches. The skin is smooth 

 and the color ranges widely from green to gray or crimson, the darker 

 mottling being also highly variable. The fins are prettily barred. The 

 preopercular spine is slender and forked. 



The Wooly Sculpin, Dasycottus setiger (B6an), (Pig. 69) is a 

 species having a very large head with numerous bony tubercles over 

 its surface. The skin covering the head supports a large number of 

 filamentous growths which suggest the common name. The skin is 

 without scales and the preoperculum bears two spines at its angle. The 

 tail fin is rounded in outline. It attains dimensions of 8 inches. 



Kincaid's Sculpin, Malacottus kincaidi (Gilbert), is related to the 

 two preceding species. It is entirely devoid of scales and the spinous 

 dorsal is separated from the posterior part of the fin by a deep notch. 

 The preoperculum is armed with three slender diverging spines. A 

 series of mucous pores is arranged along the lateral line and similar 

 pores are scattered over the surface of the head. All of the fins are 

 more or less barred and mottled. The back and sides are gray with a 

 number of irregular dark blotches. 



The Sailor-fish, Nautichthys oculofasciatus (Girard), (Pig. 75) is a 

 species of such unusual appearance one would hardly take it to be of
