1. Leucozonia (latirus) cingulifera, 



Lam. The Knobby Cingula. Florida to 

 West Indies. There are many types of 

 this genus found throughout the world 

 and this is one of the fine larger forms.

2. Aporrhais occidentalis. Beck. The 

 Duck Foot, Gulf of St. Lawrence to No. 

 Carolina, usually in 50 to 550 fathoms. 

 Rarely found to any extent on the 

 beaches but the fishermen bring them 

 up in their nets. More are found in the 

 stomachs of fishes. Fairly rare.

3. Bulla striata, Brug. Spotted Bub- 

 ble Shell. Clearwater, Florida. This 

 seems to be a iavorite locality but it 

 does not seem to be very common with 

 the shell trade. A smooth, neat solid 

 species, that has been reported only from 

 this locality. \V\" 20c 



4. Buccinum undatum, L. Common 

 Whelk. Labrador to N. J. Circumboreal. 

 The shells of this genus are usually un- 

 colored and common in cold water. Many 

 wonderful forms have been dredged in 

 the northland, but rarely seen in collec- 

 tions. 2 to 2Y2" 50c 



5. Dolium (Tontia) galea, L. Chan- 

 nelled Cask Shell. N. C. to West Indies. 

 A large thin shell, with round aperture. 

 Very rarely found on the beaches and 

 does not seem to be very common any- 

 where. Attains 4 to 8". Smaller shells 

 are better marked than larger specimens.

6. Argonauta argo, L. The Paper 

 Nautilus. Mass, to Florida. The Argo- 

 nauta belong to the great class Cephla- 

 poda, which includes Octapus, Squids, 

 etc. They are, however, closely allied to, 

 if not true mollusca. The female Argo- 

 nauta is much larger than the male, and 

 constructs this very thin glass-like shell 

 in which to lay its eggs. When full of 

 eggs, she clasps it to her body and re- 

 tains same until the young are hatched, 

 when the shell is discarded and finds its 

 way to the shores. The mollusk never 

 lives in the shell, like other mollusks, 

 and is never attached to it. There are 

 some 20 species scattered over the tropi- 

 cal world. 2V2 to 12". 2.00 per inch. 



7. Nerita peleronta, L. Bleeding Tooth. 

 St. Augustine, Florida to West Indies. 

 This is one of the handsomest and finest 

 of the some 200 forms scattered over the 

 world. It attains nearly 2", often of most 

 brilliant colors, and an operculum that 

 perfectly lits the toothed aperture. 5 for 

 25c. 



8. Anomia simplex. Orb. (ephippium) 

 Big Saddle Shell. Nova Scotia to West 

 Indies. One of the largest species of the 

 east coast, one side flat and other con- 

 vex, the flat valve being much the thin- 

 nest, as it is so often attached to some 

 other shell. Of a horn-color. IVfe" 25c 



9. Calliostoma canaliculatum. Mart. 

 The Channelled Top Shell. California 

 coast. A conical ridged shell of a grayish 

 color. Underneath it is an iridescent 

 pearl. One of the two finest species on 

 the West Coast. (Not found on East 

 Coast). 11/2" 35c 



10. Thais floridana. Con. The Com- 

 mon Purpura. N. C. to West Indies. 

 There are a number of variety forms in 

 its wide range. Of a brownish color, 

 some shells are twice as large as the type.

11. Zirfaea crispata, L. The Great 

 Piddock. Labrador to South Carolina. 

 Usual specimens are 3", white and the 

 two valves only touch at one spot. The 

 shell is very thin and fragile and they 

 burrow in the sand for protection. Also 

 found on West Coast. 1.00 



12. Pholas costata, L. Angel Wing 

 Shell, Massachusetts to West Indies. A 

 thin, white shell, fond of burrowing in 

 the sea sand. This is one of the finest 

 and largest species in the genus in the 

 world, attaining as much as 7". The shell 

 has no hinge, and there are two interior 

 plates which hold the viscera of the mol- 

 lusk in place.

13. Martesia cuneiformis. Say. Little 

 Piddock. Connecticut to West Indies. 

 The cut is much enlarged, as the shell 

 is seldom over one inch and you will 

 find them usually burrowing in colonies 

 in a wooden plank along the sea shore. 

 There are four species on the east coast.

14. Cuspidaria costellata, Desh. Little 

 Dipper Shell. North Carolina to West 

 Indies. It is usually white and of the 

 peculiar shape shown in illustration. 

 Most of the 28 species on our coast are 

 from deep water and seldom seen in col- 

 lections. This little fellow ranges from 

 1/2 to 1". 50c 



15. Terebratulina caput-serpentis, L. 



Northern Lamp Shell. Maine. The illus- 

 tration shows the interior of the shell 

 and its peculiar structure. This interior 

 structure separates the Brachiapods 

 from true mollusca. The shell is of a 

 gray color and is usually found in clus- 

 ters attached to some object, such as 

 stone or wood. 50c
