1. Megalatractus proboscidifera. Lam. 

 Australian reefs. One of the two largest 

 marine shells in the world. Of a uniform 

 yellow color it attains 20" or more but 

 fine 15 or 16" shells are usually the best 

 color and upper whorls are more apt to 

 be perfect. It is a comparatively light 

 and thin shell for its immense size. The 

 other unusual marine univalve shell is 

 the Fasciolaria gigantea of Florida. The 

 pair shows the highest development of 

 size in univalve shells. It is placed with 

 the Melongenas. 5.00 to 10.00 



2. Nautilus pompileus, L. East Indies. 

 When this shell is polished it is com- 

 monly called the Pearly Nautilus. In 

 the New Hebrides and other island 

 groups of the South Seas the fishing 

 for Nautilus is a regular business of the 

 natives. They fashion a barrel of bam- 

 boo, with a curved inward opening at 

 each end, place a rock inside to make 

 it sink, put in the bait and drop it to 

 the bottom in 30 to 50 ft. of water. 

 Sometimes there will be a long string 

 of these traps connected with ropes and 

 buoys. The Nautilus mollusk crawls 

 along the bottom, goes into the barrel 

 after the bait and seldom knows how 

 to get out. Twenty million years ago 

 there were several hundred species but 

 now there are only two living forms. 

 Oliver Wendell Holmes wrote a poem 

 on the Nautilus which is often read in 

 schools. You will find much informa- 

 tion on this species in the August 1935 

 number of the National Geographic 

 Magazine. The upper cut shows a shell 

 cut in half with the air chambers. Size 

 6 to 9". 3.50 



3. Columbrarium pagoda. Less. Japan. 

 A very odd shell with spire like a Pagoda 

 and long slender basal appendage. There 

 are three forms known. It seems to be 

 allied to the Turris. Is of brownish 

 color. 3" 2.00 



4. Tibia (Rostellaria) curvirostris. Lam. 

 Philippines to Red Sea. This is a strong 

 robust highly polished shell with elon- 

 gated spire and stubby spiral base. A 



brilliant yellowish species which has 

 always been much admired by shell 

 collectors but so often not on the market 

 in sufficient quantity. 6" 2.50 



5. Latirus polygonus, Gmel. Mauritius. 

 A finely marked striking species and one 

 of the largest of the genus. It is yellowish- 

 white and the ridges are splashed with 

 rich dark brown. 2 1 A" 1.00 



6. Latirus craticulatus, L. Mauritius. 

 This species has spiral lines of red color 

 and prominent ridges. I have had it 

 from Philippines. 2" 1.00 



7. Latirus leucozonalis. Lam. West 

 Indies. A comparatively smooth species 

 of a brownish color. Most of the shells 

 of this genus are ridged in all directions. 



1V4" 50c 



8. Latirus smaragdulus. Lam. Philip- 

 pines. A dark blackish shell which is 

 often completely covered with bryozoans 

 of all sorts. Usually must be well cleaned 

 to know what you have found. IWSOc 



9. Latirus nassatulus. Lam. Mauritius. 

 A short stubby species with prominent 

 ridges of a whitish color. The aperture 

 is deep pink. IVz" 50c 



10. Dolium (Tonna) ringens. Swain. 

 Panama. The Cask Shell. Must be fairly 

 common from Lower California south- 

 ward as they used to be sold com- 

 mercially in all sizes from 3 to 8 inch. 

 They are almost perfectly round with 

 flaring aperture. There are 35 species 

 of this genus in the world most of which 

 are comparatively thin shells but this 

 one is a solid fellow. Lives under edges 

 of rock at low tides. 1.00 to 2.00 



11. Dolium (Malea) pomum, L. Philip- 

 pines. A handsome shell of pure white 

 or flesh color. They are round, with a 

 slightly flaring aperture. Burrows in 

 sand bars. 2 to 3" 50c to 1.00
