Alfred Bell — Fossils of East Anglian Boxstones. 411 



Mitra cf. fusiformis, Brocchi. 



Mitra fusiformis, Cerulli-Irelli, Pal. ital., vol. xvii, p. 235, pi. xxi, fig. 19, 

 1911. Mus. Pract. Geol., London. 

 [The reference is founded on the cast of a long body and next whorl, 

 60 mm. long, 25 mm. broad, with a nearly straight figure. Mitra 

 Venayssina, Fontannes, Moll. Plioc. Vail, du Rhone, vol. i, p. 79, pi. vi, 

 fig. 1, is closely allied to it.] 



Sipho gregarius (Philippi), pars. 



Fusus gregarms, Beyrich, Zeitsch. deutsch. Geol. Ges., vol. viii, p. 59, 

 pi. v, figs. 7-8, 1856. Mus. Norwich, Ipswich. 



Sipho lineatus (de Koninck). 



Fusus lineatus, de Koninck, Coq. foss. Basele, p. 18, pi. iii, figs. 1, 2, 1837. 

 Mus. Pract. Geol. London, Ipswich, York. 



Sipho muitisulcatus (Nyst). 

 Fusus multisulcatus, Nyst, Coq. foss. Beige, p. 494, pi. xl, fig. 1, 1843. 

 Mus. Pract. Geol. London. 

 [Nyst altered de Koninck's specific name lineatus to multisulcatus, but his 

 figure is not the same as de Koninck's, which shows a shell having a longer 

 spire and canal, and narrower in proportion. They may be varieties of 

 a polymorphous form, but as both varieties occur in the boxstones they 

 are given accordingly for what they are worth.] 



Sipho major, A. Bell. 

 Sipho major, A. Bell, Journ. Ipswich Field Club, vol. iii, p. 9, 1911. 

 Fimis erraticus, var., Harder, Danm. Geol. Underseg., vol. ii, p. 83, pi, vi, 

 fig. 31, 1913. ' 



Mus. Ipswich. 

 [This is a large shell, the three lower whorls measuring 80 mm. in length 

 with a breadth of 35 mm. This and the next species may perhaps represent 

 a new group, intermediate between Sipho and Fasciolaria, as the moulds of 

 the upper whorls show traces of costal ornament. Of this group Ftisus 

 (aff.) Konincki, Ravn, K. Danske Vid. Selsk. Skrift (7), vol. iii, pi. v, fig. 10, 

 might be taken as the type.] 



Sipho Ravni, sp. nov. 



Fusus erraticus, var., Ravn, K. Danske Vid. Selsk. Skrift (7), vol. iii, 

 p. 333, pi. vi, fig. 13, 1907. Mus. Pract. Geol. London, Norwich. 



Fasciolaria (Surcidofusus) erraticus (de Koninck). 



Fusus erraticus, de Koninck, Coq. foss. Basele, p. 19, pi. ii, fig. 5, 1837. 

 Nyst, Coq. foss. Beige, p. 496, pi. xl, fig. 2, 1843. 



Mus. Pract. Geol. London, Ipswich. 



Isiomesus nudum (S. V. Wood). 



Buccinum nudum, S. V. Wood, Mon. Crag Moll., Suppl. 2, p. 1, pi. i, fig. 1, 

 1879. 



Liomesus ventrosus (Beyrich). 



Fusus veyitrosus, Beyrich, Zeitsch. deutsch. Geol. Ges., vol. viii, p. 35, 



pi. ii, figs. 3-5, 1856. 

 Buccinopsis Dalei, Ravn, K. Danske Vid. Selsk. Skrift (7), vol. iii, p. 313, 

 pi. v, fig. 1, 1907. 



Moore and Stanley Coll. 

 [Many of the shells found in the Scaldisien beds in Belgium figured as 

 B. Dalei, Sow., are much nearer to this species than to those in the English 

 Crag. Fig. 4 in Beyrich's plate is an almost exact delineation of some of 

 the Belgian forms.]
