of the dorsal fin. The spine on the preoperculum is long and bifurcate. 

 The length of the specimens was one and one-half inches. 



The Northern Sculpin, IceHnus iorealis (Giltert), (Fig. 65) has a 

 set of enlarged plates along the lateral line and another series along 

 the back, but the space between these is devoid of scales. There are a 

 number of processes on the preoperculum. No filamentous spines are 

 developed in connection with the dorsal fln. The length is 4 inches. 



The Reindeer Sculpin, Tarandichthys fllamentosus (Gilbert), is so 

 named from the antler-like processes on the preopercular spine, which 

 suggest the horns of the reindeer. Another striking feature is the 

 development of the anterior spines of the dorsal fin which are length- 

 ened and filamentous. This species is three and one-half inches in 

 length. 



The Star-topped Sculpin, Astrolytes fenestralis (Jordan and Gil- 

 bert), is about five inches in length, and is distinguished by the pres- 

 ence of a number of star-shaped scales on the top of the head. The 

 lateral line is unarmed and the preopercular spine is provided with a 

 single hooked process. None of the dorsal spines are filamentous in 

 form. 



Harrington's Sculpin, Axyrias harringtoni (Starks), (Pig. 68) was 

 first taken at Port Ludlow, Washington, in 1895 and was named in 

 honor of Dr. Mark W. Harrington, who was at that time President of 

 the University of Washington. It was later found in the San Juan 

 Islands by Mr. Starks. It is about four inches long and has a consider- 

 able development of short cirri on the top of the head. The space 

 between the eyes is concave. The ground color is olive with five bars 

 of brown on the back. 



Artedi's Sculpin, Artedius lateralis (Girard), is another of the 

 small sculpins. It is similar to Axyrias but is five inches in length, 

 the cirri are absent from the top of the head, and the space between 

 the eyes is flat. In color it is richly mottled with olive, red and black. 



The Red Sculpin or Irish Lord, Hemilepidotus Uemilepidotus (Tile- 

 sius), (Pig. 67) is one of our larger species, extending over IS inches. 

 The back and sides have two separate bands of rough scales and the 

 spinous dorsal is notched. 



The Great Sculpin or Kalog, Myxocephalus polyacantliocephalus 

 (Pallas), (Pig. 74) is a species which attains a length of two feet. The 

 top of the head is covered with small warty protuberances. The pre- 

 opercle has three strong straight spines. The dorsal fins are- barely in 

 contact. 



The Buffalo Sculpin, Enophrys hison (Girard), (Pig. 71) is one of 

 our common species. It is about a foot in length and has a long simple 

 spine on the preopercle. The body is without scales, but along the 

 lateral line there is a band of coarse bony plates.
