96 LAGENA. 



L. ciNGULATA, Lam. PI. TO, fig. 180. 



Chestnut, with distant, flat, somewhat raised, revolving bands 

 of dark chocolate ; aperture white. Length, 1*5-2 inches. 



Panama to Mazatlan ; soxhtliern extremity of Florida, 



W. W. Calkins. 



Mr. Calkins is the only authority for the occurrence of this 

 common West Coast species in the Atlantic waters ; his locality, 

 however, is not to be doubted : — besides, several other Pacific 

 species have been discovered recently on the Florida coast. 



Subgenus Lagena, Schuin. 



L. suBROSTRATA, Gray. PI. 70, figs. 181, 182. 



Yellowish brown, white within the aperture. 



Length, 1*6 inches. 

 Bay of Montija, W. Columbia (^in sandy mud, 13 fathoms— Cuming). 



L. agrestis, Anton (fig. 182), is founded on younger specimens 

 of this species. Its generic position is very doubtful ; Reeve 

 considers it a Pyruia (= Mdongena), and H. and A. Adams 

 have put it in Clavella ; it is also allied to Cantharus distortus. 

 The columella plaits are sometimes obsolete. 



L. LEUcozoNALis, Lam. PI. 70, figs. 183, 184. 



Brown, with a white raised band below the periphery, ter- 

 minating in a tooth on the lip ; upper part of whorls sub- 

 nodulous. Length, l-l-.'j inches. 



West Indies ; Honduras. 



Different as this species appears at first sight in its form and 

 want of distinct shoulder and tubercles, there is almost sufficient 

 evidence to justify its being made a synon3-m of L. cingulifera. 



L. SMARAGDULA, Linn. Ph 70, figs. 185, 18G. 



Chestnut-brown, closely encircled by numerous, narrow, equi- 

 distant white lines ; aperture white. Length, 1-2 inches. 



Philippines ; Viti Isles. 



Undetermined Species of Peristerniinse. 



None of the following species have been figured, nor have they 

 been identified by the monographers of the Turhinellse. 



TURBINELLA STRIATA, Gra}'. No locaUty.
