RAPHITOMA NEVROPLBURA. 383 



Dimensions. L. 20 mm. B 8 mm. 

 Distribution. — Not known Living. 



Fossil: Coralline Crag: Sutton, Gedgrave. Newbournian : 

 Waldringfield. 



Remarks. — The fossils from the Coralline Crag, one belonging to the Jermyn 

 Street Collection, the other to the Sedgwick Museum, Cambridge, and here 

 described as Raphitoma concinnata, seem to correspond with one of those figured 

 by Wood in 1848 (pp. n't., fig. 11 a) under that specific name. There is another 

 from Waldringfield in the Ipswich Museum, somewhat worn, which may be the 

 same. Wood's fig. 11 b is possibly a different species. 



In 1871 Jeffreys identified this shell with Pleitrotoma decussation, Philippi, but 

 Wood did not accept this view, nor can I ; our Crag shell does not appear to me to 

 agree, even remotely, with Philippi's figure. 



In 1872, in his first Supplement, Wood figured a Crag fossil as P. hispidvla 

 {op. cit., p. 42) which I have referred on p. 259 to the Belgian Raphitoma similis, 

 Nyst, giving on my PI. XXIX, figs. 27 — 29, verified examples of both species. In 

 the paragraph quoted, Wood suggested that R. concinnata might be regarded as a 

 variety of 1'. hupidula. A review of all the facts, however, leads me to consider 

 it distinct and to revert to my old friend's original name of R. concinnata for it, as 

 the brothers Bell did in 1872 (op. cit.).

Specific Characters. — Shell slender, fusiform ; whorls 8 or 9, but little convex, 

 somewhat depressed below the suture ; ornamented by thick, rounded, sinuous 

 costas and by very fine transverse striations ; spire elongato-conical ; suture slight ; 

 mouth oblong, narrow, angulate above ; labial sinus indistinct ; outer lip gentiy 

 curved, nearly continuous with the canal. 



Dimensions. — L. 14 mm. B. 5 mm. 



1 As stated on p. 256 of the present Memoir, and for the reason there given, I retain the feminine 

 termination for the specific names of the present group of shells.
