Pliocene of Black River, South Carolina ; Caloosahatchie beds at Shell 

 Creek and Punta Gorda, S. W. Florida, rare. Recent in the West Indies from 

 Jamaica to the northern coast of Brazil, and westward to the Swan Islands. 



This species has been alleged to come from the Coromandel coast, but I 

 have never seen any recent specimens except from the West Indian region. 

 It is much confused by Tryon with quite distinct forms from West America 

 and elsewhere. The idea of uniting it with T. ringens appears absurd. The 

 first binomial appellation referring solely to this species is that of Link. The 

 name Cantharus has no standing in nomenclature, and should not be adopted. 



This species in Pliocene times extended its range as far as South Carolina ; 

 the fossil Floridian specimens are finely grown and larger than the average of 

 recent ones, but have the characteristics of the species unmistakable. I have 

 not seen it from the Floridian Post-Pliocene, and its place in the Post-Pliocene 

 and recent fauna has been filled by the allied, but sufficiently distinct, form 

 named T. tincta by Conrad. The Punta Gorda fossil is noted by Mr. Willcox 

 as from the upper layers of the Pliocene in what has been known to collectors 

 as the Venus cancellata bed. 



Lavibuccinuni prorsum Conrad {+ lineatu7?i Heilprin) of the Eocene of 

 Wood's Bluff, Alabama, is a genuine Pisania of the typical sort, except that 

 the subsutural callus is not drawn into a ridge. It may be considered as the 

 forerunner of the genus. Neptunca constricta Aldrich also belongs in this 

 vicinity. On the other hand, the species doubtfully referred to Pisania with 

 the specific name of -diibia by Mr. Aldrich, would seem to be more nearly re- 

 lated to Urosalpinx, like Fusus trossulus Conrad. Pisania Claibornensis Whit- 

 field (1865), as pointed out by Mr. Aldrich, is not a Pisania, but is the young 

 of Ranella {Ranellind) Maclurei Conrad, of which he gave a figure and name, 

 but no description, in 1835. The young was both described and figured in 

 1841 by H. C. Lea (Sill. Journ. xl. p. 99, pi. i, fig. 16) under the name of 

 Triton pyramidatum. Lea's type is still preserved at Philadelphia. CantJiarus 

 cumberlandianus Gabb is a Corailiopldla, and has nothing to do with Cantha- 

 rus {= Tritonidea).
