128 TRANSACTIONS OF THE WAGNER FREE 



F. caloosaensis were transposed so that the latter appears on the Blake plates 

 instead of the former. I now add the figure of F. tirnessus (Plate 7, figure 6), 

 which will be useful for comparison. The nucleus oi F. caloosaensis is exactly 

 like that of some Fasciolarias and is elegantly sculptured. Both the spire 

 and canal seem to have been more than usually subject to injury and conse- 

 quent distoi'tion. 



Fusus sp. indet. 



A small, elegantly sculptured species of F?tsits, something like F. Meyeri 

 Aldrich, but with the whorls not keeled at the periphery and the ribs elevated 

 at the shoulder, was noticed among the shells represented in the molds con- 

 tained in the " Cerithium rock " of the Hillsboro River, Tampa. Only part 

 of the lower whorl and the canal were preserved, so I have not thought it best 

 to do more than note its presence there. 



Pusus mississippiensis Conrad. 

 F. ftiississippiensis Conrad, Journ. Acad. Nat. Sci. Phila. i., 2d series, p. 117, pi. 11, fig. 



34, 1S48. 



A silicified specimen of this species is included in a piece of rock collected 

 by Mr. Willcox at Martin's Station, Marion Co., Florida. 



Fusus? quinquespinus n. s. 



Shell bearing a singular resemblance in many of its characters to Papil- 

 Una duinosa and the young of the spiny form of Meloyigena scnlptiirata, and 

 best described by comparison with them. It has not the apical whorls and 

 large nucleus of Papillina ; the whorls are not appressed at the suture as in 

 P. diunosa ; it has five spines instead of seven on the last whorl; the pillar 

 wants the thick layer of callus, and it has a wider, shorter and more curved 

 canal than P. dmnosa ; the peripheral spines are continued to the tip, which, 

 in my best specimen, has lost the nucleus, which, however, was small. What 

 remains has three and a half whorls, and there were originally at least five. It 

 measures, including the spines, 35 x 21 mm. In other respects it closely re- 

 sembles P. diunosa, and also the young of Melongena sadpturata, except in 

 the slope of the upper part of the whorls. I am much puzzled by this singu- 

 lar fragment, which seems distinct from anything else, and for the present will 

 call it Fnsiis, though I am not certain that mature specimens would indicate 

 its place to be with Fusus proper. 



It was collected by me at Ballast Point from the marl of the silex-beds, 

 and impressions in the Cerithmm limerock described by Heilprin, though not 

 conclusive, indicate that it is represented also in that fauna. 



Fusus (Chrysodomus ?) nexilis n. s. 

 Plate 8, figure 4. 

 Shell small, with two nuclear and six subsequent whorls, transversely ribbed 

 and spirally threaded ; nuclear whorls at first smooth, normally coiled, the sec-
