1. Pterocera lambis. L. Spider Shell. 

 Pacific generally. One of the most com- 

 mon shells of the genus and has been 

 sold commercially for many years. 

 Somewhat variable in shape but the 

 general pattern is the same. Usually 

 marked with blotches of dark color on 

 back. Aperture white. 5 to 6" 50c to 1.00 



2. Pterocera rugosa. Lam. Scorpion 

 Shell. East Indies. It is a very common 

 shell and usually shape of cut. Has 

 been and is sold commercially. The six 

 hooks in the form indicated usually 

 identify the shell, but there is another 

 shell very similar with reddish aper- 

 ture that attains twice the size of this 

 shell. 5 to 6" 1.00 



3. Pterocera violacea. Swain. Philip- 

 pines. This is a lovely white shell with 

 rich violet aperture and must be fairly 

 rare as none of my P. I. collectors 

 have ever sent me a specimen. The nu- 

 merous fingers along the edge differ from 

 all other known forms. 3Vfe". Rare. 



4. Pterocera elongata. Swain. Mauri- 

 tius. The stubby spines, flat lip and 

 rich aperture with two spikes at top, 

 will always easily identify this shell 

 wherever found. I suspect it is fairly 

 common but never seen on our market 

 as yet in any quantity. 3V2" 2.00 



5. Pterocera scorpio, L. Philippines. A 

 highly colored Scorpion Shell which is 

 sold commercially but not always on 

 the market. The aperture is a rich violet 

 color and the 6 or 7 arms make it a very 

 attractive shell. 4" 1.50 



6. Pterocera aurantia. Lam. Philip- 

 pines. The yellow Scorpion is a slender 

 shell, more so than any of the other forms 

 of the genus. Unique in having real 

 hooked fingers. The aperture is a bril- 

 liant yellow, fairly common. 1.00 



7. Pterocera millepeda, L. Philippines. 

 I had a large number of these shells 

 sent me from Sulu Sea, P. L, and while 

 the fingers were stubby as shown in 

 cut they were usually slightly curved 

 upwards. The back is lined with brown 

 and aperture same. There are usually 

 10 or more spikes. 3V2" 1.25 



8. Strombus luhuanus, L. Japan Sea 

 and Pacific generally. A very pretty 2" 

 shell with a brilliant red aperture bor- 

 dered with black on the body opposite 

 the lip. Quite common. 2" 25c 



9. Strombus gracilior. Sow. West Mex- 

 ico. Of similar shape and habits to the 

 very common pugilis of Florida waters. 

 This shell is almost invariably a light 

 yellow with fuzzy periostracum. 



2 to 3" 50c 



10. Turbo tesselatus, Kien. Lower Cal- 

 ifornia. The shell is of a grayish-brown 

 color with dots and waves of darker 

 color over entire surface. The base of 

 the shell has a greenish cast. Fairly 

 common. 2 to 3" 75c 



11. Turbo undulatus, Chem. Tasma- 

 nia. The entire surface is covered with 

 zigzag markings over a fine green color, 

 it seems to be a hard shell to clean so as 

 to show all of its very attractive features. 

 This is true of many of the shells of this 

 great genus. 2 to 3" 1.00
