1. Haliotis cracherodi. Leach. Black 

 Abalone. Oregon to Lower Calif. It has 

 a smooth back, and inside is iridescent. 

 It takes a high polish and the brilliant 

 black markings contrast strongly with 

 the white pearl. 4 to 6". 



Natural 50c Highly polished 1.50 



2. Haliotis fulgens, Phil. Blue Abalone. 

 Southern California. This species attains 

 a larger size than the preceding, interior 

 is more highly colored and the back takes 

 a fine polish, showing up iridescent 

 colors. 6 to 7". 



Natural 1.00 

 Highly polished 3.00 to 5.00 



3. Haliotis rufescens. Swain. Red Aba- 

 lone. California Coast. This is the largest 

 form on the West Coast and like the 

 others, the back takes a high polish, show- 

 ing brilliant patches of fiery red. The 

 Haliotis hide among the rocks and as they 

 grow older settle down to a permanent 

 location. The back is often so fully 

 covered with sea growths, it is hard to 

 detect the shell from the rocks. A solid 

 iron bar is necessary to detach them. 

 Most of the species are now protected by 

 law. 7 to 8".

4. Haliotis, White form. This cut is 

 used to illustrate the species that are 

 naturally white and devoid of other 

 color. The largest come from Japan and 

 others from Mediterranean, etc. Most of 

 the white species are rather thin and for 

 that reason, not so extensively used for 

 commercial purposes. They all take a 

 high polish. 5 to 6". 



Natural 50c Highly polished 2.00 



5. Murex festivus. Hinds. The Festive 

 Rock Shell. San Pedro, Calif. There are 



three frills on each whorl that are re- 

 flexed, alternating with rounded knobs. 

 When cleaned it is a very attractive shell. 

 Prefers the warmer waters of the south 

 coast. 2" 50c 



6. Ceratostoma nuttalli. Con. Nuttalls 

 Hornmouth. Southern California. Has 

 three prominent ridges and a small sharp 

 horn at the base. Of a rusty brown color, 

 if not removed in cleaning. Rather 

 attractive. 2" 50c 



7. Tritonalia poulsoni, Nutt. Poulson's 

 Rock Shell. Southern California. The 

 surface is strongly marked with knobby 

 varices. A fine grayish species that is 

 white inside. 2" 50c 



8. Polinices Lewisii, Gould. Lewis' 

 Bulls eye, Puget Sound, Wash., and most 

 of the West Coast. This is the largest 

 species of the genus and believed to be 

 the largest in the world. It is carnivorous. 

 Has been seen to bore a hole in the um- 

 bones of a bivalve in 30 minutes. Has 

 leathery operculum. Attains 4 to 5". 1.00 



9. Tegula funebralis. Ads. The Black- 

 Top Shell. California Coast. It is jet 

 black and like all others of the genus, 

 clings to the rocks often in the surf where 

 it is hard to collect the specimens. One 

 of the finest of the genus. W2" 25c 



10. Astraea undosa. Wood. Wavy Tur- 

 bine Shell. Southern California. The sur- 

 face is wavy, covered with a thick peri- 

 ostracum, which when removed and the 

 surface buffed, shows a shiny pearl sur- 

 face. One of the largest and heaviest of 

 the genus attaining 5 to 6" but the 

 medium size shells with the attractive 

 periostracum are best.
