The Irish Naturalists 



[ July, 



Varietates. 



Var. I. rufa, Phil. 



Melania ru/a, Philippi, 1836, En. Moll. Sic, I. p. 156, pi. ix., fig. 7. 

 This has flattened whorls and is of a uniform reddish colour. I find our 

 few specimens quite similar in every way to Mediterranean types 

 which I owe to the kindness of the Marquis of Monterosato. 



Var. 2. crenata, Brown. 



[Pyrajfiis crenatus. Brown, 111, Rec. Conch. Gt. Br. and I., 1827, pi. ix., fig. 



53 (no description, figure too small to show sculpture)]. 

 P. crenatus. Brown, 1857, 111., etc., 2nd Ed., p. 14, pi. ix., fig. 53. 

 I see no reason for refusing to admit Brown's name at an}' rate so far 

 as the second edition of his work is concerned. The description is 

 far better than others which have been accepted without question, 

 and is unmistakable. The form differs from the var, rufa in its 

 "pellucid white colour" (Brown). We obtained a few live examples. 

 Various forms intermediate between the type and the varieties were 

 also noticed. 



Liostomia clavula, Lov. {Odosto^nia clavula). — Of this species, which 

 in our former dredgings was found only in the dead state, one live 

 specimen turned up this time. 



Pulsellum lofotense, Sars. (^Sipho^iodentaliuvi). — A small dead example. 



Neolepton obliquatum, Monterosato, Nuova Rivista, p. 12. This 

 species, the most interesting of our finds, is represented by eleven 

 valves. That shells measuring, as our larger ones do, 2-4 mm. by 

 I -8 mm. should have escaped observation will be surprising only 

 to those who have not attentively studied the smaller marine Pele- 

 cypoda, amongst which the separation of immature forms from adult 

 niinutiora is a matter of very great difficulty. As the species has never 

 been figured, I give a sketch of one shell (Fig. 2) and an outline of 

 another of slightly different contour (Fig. i). It will be found quite

unlike any other British form. The outer surface is covered with 



fine and close-set concentric striae, which are however so strong as to 



give the shell a rough appearance. 

 Its distribution is Palermo (Monterosato), Livorno (Uzielli), Eleusis, 



Greece (G. W. C.) 

 My examples from different localities differ slightly in form, but all are 



easily recognizable as belonging to the same species.
