Fasciolaria papillosa reevei Jonas in Philippi PI. 48, fig. 287 



Alt. to ISO mm. General character of F. papillosa, smaller, 

 thinner; early whorls with nodulous shoulder similar to the species, 

 body whorl with smooth shoulder, not ribbed nor nodulous. 



Found on the Gulf Coast of Florida with F. papillosa. 



Fasciolaria tulipa^o^ (Linne) PI. 35, figs. 237a, b 



Alt. to ISO mm. Shell fusiform, seven to nine convex whorls; 

 well-defined sutures; ground color light with interrupted spirals 

 of brown, more or less maculated with brown or amber color; thin 

 periostracum; revolving sculpture of flat ridges and shallow grooves, 

 strong and wrinkled below sutures; regularly spaced growth lines; 

 aperture long-oval, outer lip simple, finely lirate within; columella 

 inflected, with two oblique folds below; canal short, open, oblique. 



From littoral zone to five fathoms. 



Fasciolaria tulipa "scheepmakeri (Dunker) Melvill" corre- 

 sponds with the typical form in all general characters. Its surface 

 is rugosely sculptured with spiral ribs and ridges. 



Egg capsule of Fasciolaria tulipa (Linne) PI. 53, figs. 353a, b, c 



Egg capsules of Fasciolaria tulipa and F. hunteria resemble 

 those of F. papillosa in their vase shape but are smaller, of smooth 

 texture, and always fixed to a firm base. F. tulipa usually selects 

 a dead shell for support, while F. hunteria- is satisfied with an old 

 wood piling or another egg case if a suitable shell is not at hand. 

 She continues her egg laying even when left dry between tides. 



Individual capsules of F. tulipa are from 2S to 30 mm. in height, 

 with finely fluted edges at the top, and like others of the genus, have 

 a small round central opening in top of capsule closed by a thin 

 disc. From 20 to 75 capsules compose a compact rosette, with 8 to 

 20 embryos in each capsule. Development of embryos is unequal, 

 some in the same capsule being far more advanced than others. 

 This is also true of others of the genus.
