SIMPSON — CONTRIBUTIONS TO THE MOLLUSCA OF FLORIDA. 49 



I have no doubt that there are errors in this catalogue. It has 

 been prepared in haste, in the odd moments of a very busy life. I 

 have but little literature on the subject, and have never had any oppor- 

 tunity to examine extensive libraries or collections; — in fact, a por- 

 tion of my Florida species I have not yet had time to unpack and 

 compare. My work has been mostly done in the field. I thought it 

 better, however, to do something than to wait for leisure and oppor- 

 tunities which might never come. I therefore ask the kindly consider- 

 ation of all into whose hands it may fall.

CATALOGUE. 



[In the following catalogue, such species as have been obtained only from other collectors 

 are designated by an asterisk (*). All others have been collected by myself.] 



Octopus vulgaris L. Washed up on Long Key. 



Octopus rugosus Bosc. ? Florida Keys. 



Ommatostrephes ? A specimen washed up on Long Key, the pen 

 of which is referred by Mr. Dall to this genus with doubt. The animal 

 was partly decayed when found. 



Spirula per onii Lam. Florida Keys; not rare. 



Hyalea trispinosa D'Orb. One shell found washed up on the lower 

 end of Anna Maria Key. 



Murex pomum Gm. West coast. Very abundant at Sannibel Island 

 and southward. 



*Murex adustus Lam. A single fine specimen was received from 

 Mr. Isaiah Greegor, of Jacksonville, who reports it from the east coast. 

 Tryon gives its locality as Indian Ocean, Phillipines, and Japan ; but 

 Dall, in his catalogue of West Indian shells, reports it from Cuba, on 

 the authority of Pfeiffer. 



Murex recurvirostris Brod. Anna Maria Key, one specimen; San- 

 nibel Island; Marco, and vicinity. 



Murex brevifrons Lam. Two slightly worn specimens, found at 

 Key West, are referred to this species. 



Murex chrysostomus Gray. One young shell from Sannibel Island. 

 I have seen a fine full-grown shell, belonging to Mr. R. C. Stuart, of 

 Tampa, found on the west coast, which is probably this species. 



Murex salleanus A. Ad. West coast; more abundant at Sannibel 

 Island and southward. 



Murex nuceus Morch. Tampa Bay; Tortugas. A number of speci- 

 mens were dredged, living, in eight fathoms of water, in Tampa Bay. 



Murex intermedins C. B. Ad. Worn specimens were found at Key 

 West. I have this shell from the Bermudas and Honduras, east coast.
