13a. Preopercular spine simple, very long and strong, longer 

 than eye; body robust, its greatest depth less than 4 

 times in standard length ; gill membranes broadly united 

 to isthmus; dorsal rays VIII, 9; anal rays 9. Range: 

 Alaska to Pt. Conception, California. Marine. Abun- 

 dant. 

 Buffalo Sculpin 227. Aspicottus bison Girard 



13b. Preopercular spine bifid (sometimes simple) shorter than 

 eye; body long and slender, its greatest depth about 8 

 to 9 in the standard length; dorsal VIII to X, 21 or 22; 

 anal 23 or 24. 



14a. Eye small 3^3 in head ; interorbital space scaly. Range : 

 Puget Sound to Santa Catalina Island. Marine. Rare. 

 228. Radulinus boleoides Gilbert 



14b. Eye larger 2.6 to 3.3 in head; interorbital space naked. 

 Range : Puget Sound to Farallon Islands, California. 

 Marine. Common. 

 229. Radulinus asprellus Gilbert 



12b. Vomer with teeth; palatines with teeth. 



15a. Body with 2 separate bands of coarse rough scales, 

 the dorsal band meeting its fellow in front of spinous 

 dorsal ; last gill arch with distinct slit or pore behind 

 it ; lateral line without bony plates ; spinous dorsal 

 notched; preopercular spine shorter than eye. 



16a. Gill membranes not wholly free from isthmus, there 

 being only a broad fold across it, which is not at- 

 tached ; upper band of scales in about 4 rows ; skin 

 in interspace firm and thick. Range : Kamchatka to 

 Monterey Bay, California. Marine. Common. 



Red Irish Lord 



230. Hemilepidotus hemilepidotus (Tilesius) 



16b. Gill membranes wholly united to isthmus, not form- 

 ing a free fold across it (sometimes the skin is 

 shriveled and forced forward artificially making it 

 appear like a fold on poorly preserved fish) ; upper 

 band of scales in about 7 rows at its widest part; 

 skin in interspace thin and lax. Range : Cape John- 

 son, Washington to Santa Barbara Islands, Califor- 

 nia. Marine. Common. 



Yellow Irish Lord 



231. Calycilepidotus spinosus Ayres 



15b. If 2 or fewer rows or bands of scales occur on the 

 body, the dorsal band does not meet its fellow in front 

 of the spinous dorsal fin ; last gill arch without slit or 

 pore behind it (a minute pore may occur in Astro- 

 lytcs) ; gill membranes united but free from the isth- 

 mus. 



17a. Preopecular spine with 1 to 5 enlarged hooks or ant- 

 ler-like processes above, besides the 2 on the tip.
