BULLA SEMILEVIS Seguenza (Vol. xv, p. 339). 



Canon Norman, in Ann. Mag. Nat. Hist. (6), vi, 1890, p. 67, 

 states that this is the same as the later Bulla guernei Dautz. (see 

 Manual xv, p, 336), and further " it is clear also, I think, that 

 B.eburnea Dall [Manual xv, p. 339] is the same thing." The local- 

 ities quoted in Vol. xv for these synonyms, should be added to the 

 range of B. semilevis, with the following : off the south of Ireland, 

 1000 fms. (' Flying Fox ' 1889, E. A. Smith). 



Bulla diaphana Montagu, Test. Brit., p. 225, is said by Jeffreys 

 to be the young of Cyprcea europcea (Ann. Mag. N. H. [4], vii, p. 

 245, 1871).

TORNATINA PARVIPLICA Dall. Frontispiece, fig. 7. 



This species resembles T. recta Orb. in a general way, especially 

 when young, and is distinguished from it by its more rounded sur- 

 face between the sutures of the spire, and by the obsolete plait on 

 the pillar ; the adult is a much thinner yet wider shell than T. recta, 

 and reaches a length of 6'5 and a width of 3*25 mill., with five 

 whorls, beside the projecting sinistral nucleus. The spire is moder- 

 ately elevated, the top of the last whorl flattish, but without canali- 

 culation ; the surface is faintly marked with lines of growth, not 

 polished and entirely without spiral sculpture. The umbilicus is 

 not perforate, and the plait is formed by the twisting of the thick- 

 ened pillar, not superimposed upon the pillar. It is only known 

 from the lagoons. (Dall).
