104 THE NAUTILUS. 



Octopus rngosus Bosc. A few which are evidently this species, 

 one large specimen is preserved in alcohol. 



Argonauta argo L. Occasionally a shell is found after a storm. 



Loligo pealii Lesueur. Quite common. 



Ommastrephes bartramii Lesueur. One specimen, probably this 

 species, is preserved in alcohol in a private collection. 



Spirilla peronii Lam. The internal spiral shells are common 

 among the debris after storms. 



Murex ■•<pinicosfata Valenc. Living examples are rare. I have 

 seen but three. By tlie numbers found in the shell mounds and 

 fields it seems to have formally been quite plentiful and a special 

 object of capture among the aborigines. 



Urosalpinx cinereus Say. Common on oysters. 



Eapleura caudata Say. A few specimens. 



Purpura hcemastoma L. var. floridana Cour. Common on the old 

 light-house rocks. It varies greatly in form. I have specimens 

 varying from those without a shoulder or tubercles on the body- 

 whorl, to those that are shouldered and bearing two prominent rows 

 of tubercles. 



Purpura hcemastoina L. var. undata Lam. A few specimens found 

 with the above. 



Fasciolaria distans Lam. I think that this- is distinct from F. 

 tulipa L. The specimens collected here show no intermediate form. 

 It seems to have a more limited distribution. I do not remember 

 seeing any in the southern part of Florida, and among the quantities 

 of shells brought from the Bahamas I never observed one, though F. 

 tulipa L., is quite common. A color variety is occasionally found 

 here in which the maculations and revolving lines are reddish-yellow 

 to pink. 



Fasciolaria tulipa Linn. Not common. 



Fascio/aria gigantea Kien. Several specimens. I found a living 

 .specimen in the harbor nearly two feet in length. 



Fulgur earica Gmel. Common and quite destructive to the 

 oysters. 



Fulgur earica Gmel. var. eliceans Mont. Thick and gibbous, with 

 fewer and larger spines, occasionally a double row of spines on the 

 shoulder of the whorls. More plentiful than the typical. 



Fulgur perversa Linn. Common and some unusually large 

 specimens.
