HALIOTIDAE 93 



holes are open. Fished commercially below 20 feet, especially between Mon- 

 terey and Point Conception. The legal minimum size for sportsmen is 7 

 inches, and the catch is limited to 5 specimens per person per day. This is 

 a popular food and, when polished on the outside, makes an attractive mantel 

 piece. 



Haliotis corrugata Gray Pink Abalone 



Plate 2C 



Monterey, California, to Lower California. 



5 to 7 inches in length, almost round, fairly deep, with a scalloped edge 

 and strong corrugations on the outer surface. 3 to 4 large tubular holes are 

 open. Exterior dull-green to reddish brown. Interior brilliant iridescent. The 

 variety diegoensis Orcutt is the same. Abundant in its southern range. The 

 legal minimum collecting size is 6 inches. 



Haliotis fulgens Philippi Green Abalone 



Plate 2b 



Farallon Islands, California, to the Gulf of California. 



7 to 8 inches in length, almost round, moderately deep, and sculptured 

 with 30 or 40 raised, coarse spiral threads. Exterior dull reddish brown; 

 interior iridescent blues and greens. 5 to 6 holes are open. Fished commer- 

 cially in southern California. The legal minimum size is 6^ inches. H. 

 splendens Reeve, H. revea Bartsch, and H. turveri Bartsch are the same spe- 

 cies in all likelihood. 



Haliotis walallefisis Stearns Northern Green Abalone 



Westport, Washington, to Point Conception, California. 



4 to 5 inches in length, elongate, flattened, with numerous spiral threads. 

 Exterior dark brick-red, mottled with pale bluish green. 5 to 6 holes are 

 open, and their edges are not elevated. This is a small, relatively scarce 

 species. 



Haliotis assimilis Dall Threaded Abalone 



Plate 2d 



Farallon Islands to San Diego, CaHfomia. 



4 to 5 inches in length, oval, fairly deep, with weak corrugations and 

 weak to strong spiral threads. 4 to 5 holes open, tubular. Outer color mot- 

 tled with brick-red, greenish blue and gray. H. aiilaea Bartsch is a little more 

 corrugated than usual, and it may be this species. H. smithsont Bartsch and 

 H. sorenseni Bartsch appear to be giant specimens of assimilis Dall.
