]44 PLIOCENE MOLLUSCA. 



Pliocene : Iceland. 



BemarJcs. — I have a dozen specimens from Oakley of about the same size, and 

 Mr. Ogden has found another at Ramsholt, which, although belonging to the 

 ;S^. costhfer group, are smaller than the type form of that shell, and otherwise seem 

 to deserve specific distinction. 



They are specially interesting, because among some of Morch's fossils from the 

 Crag of Iceland which Dr. Ravn sent for my inspection, there are several under the 

 undescribed name of TJrosalpinx Lundgrenii which correspond with those from 

 Oakley. I have similar shells in my collection from the fossiliferous drift of the 

 Isle of Man which I received from Prof. Kendall some years ago, and there are 

 others from the same locality in the Jermyn Street Museum. 



They differ from /''. Forbesi in form and sculpture and in the greater convexit}- 

 of the whorls. In the latter species, as stated above, the outer lip is thickened, and 

 is bevelled and denticulate within. In specimens of 8. Lundr/renii, on the contrary, 

 whether from Oakley or Iceland, it is thin and not denticulate, and the sculpture 

 is finer. They are easily distinguished from the typical Crag forms of L. costlfer, 

 differing from them in size, in spiral sculpture and general appearance, and in the 

 occasional tuberculation of the longitudinal costfB — a feature which is clearly shown 

 in some of the Crag specimens and less so in the examples from Iceland and the 

 Isle of Man ; they are still more unlike the shell recognised by Morcli as repre- 

 senting 8. costlfer in the Icelandic deposits. The specimens here figured from 

 different localities belong, I think, to the same species, and I group them, therefore, 

 under Morch's name of *S'. Lundgrenii.

1894. Fusus Forhesi, Kendall, Jouru. Isle of Man Nat. Hist. Soc, vol. i, p. 419, pi. i, fig. 9. 



Specific Characters. — Shell fusiform, conical; whorls nearly flat, regularly 

 diminishing towards the apex ; ornamented by numerous distinctly marked spiral 

 ridges and by rather inconspicuous longitudinal costa; giving the sculpture a 

 finely reticulate appearance ; suture indistinct ; mouth oval, ending in a short, 

 open canal which turns to the left ; outer lip thin, not expanded ; inner lip 

 forming a slight glaze on the pillar. 



Dimensions. — L. 20 mm. B. 9 mm. 



Distribution. — Not known living. 



Fossil : Isle of Man. 



Remarks. — But one example is known of this charming little shell which was 

 discovered many years ago by the Rev. S. N. Harrison and is now at Jermyn Street. 

 It was grouped in 1894 by Prof. Kendall as a variety of 8. Forhesi, but Mr. A. 

 Bell regards it, as I do, as worthy of specific distinction. The specimen in
