388 Mr. Cosmo Melvill on the 



Turbinella striata (Gray), another species unidentified 



by Mr. Tryon, is P. crocea (Reeve and Gray). 



Turbinella sulcata (Gray) is a synonym of P. scabrosa 



(Reeve). 



***** 



Again, Latirus candelabrum (Reeve), merged as a variety 

 of Folygonus (Gmel.) by Mr. Tryon is, in my opinion, a 

 sufficiently good species. 



L. modestus (Anton). It may be difficult to trace Anton's 

 species from mere descriptions, but it is certainly not safe, 

 without more evidence, to place it as equalling L. spadiceus 

 (Reeve), and to sink the latter name as synonymic only. 



Turbinella castanea (Gray). The specimen is a variety 

 of T. cingulifera (Lamarck). 



Latirus tumens (Carpenter) (Fig. 14). If Mr. Tryon had 

 seen the unique specimen in the National Museum, South 

 Kensington, from Mr. H. Cuming's collection, and also 

 examined L. gracilis (Reeve) at the same time, he would 

 never have committed himself in the way he has done in 

 his remarks. 



L. brevicaudatus (Reeve) zxid filamentosus (Koch). Two 

 distinct species, judging by specimens I have examined, in 

 the British Museum. 



Of two species, Latirus annulatus (Bolten) and L, vexil- 

 luluni (Reeve), Tryon makes no mention — he has, therefore, 

 accidentally omitted them. 



Leucozo7iia rudis (Reeve) is, I think, sufficiently distinct 

 from L. cingulifera (Lamarck), though I agree with Mr. 

 Tryon in the other subspecies. Nor do I think Lagena 

 subrostrata (Gray) otherwise than a Cantharus : the den- 

 tition alone will tell for certain. 



Peristernia Forskdlli (T. C.) seems, at all events, a good 

 species, though allied to P. nassatula (Lamarck). 



Mr. Tryon has fallen into strange mistakes too, with 

 regard to the Engina-X<k& forms I have excluded from the
