MEI.VII.T. : ADDrn'ONS TO THE GENTS l.ATIRUS. 175 



A broad, eight-whorled shell, with elongate spire, regularly convex 

 whorls, covered with uniform spiral lirae, 22 in number on the body 

 whorl. Aperture obliquely oval, outer lip simple, thin, finely crenate, 

 canal abbreviate, surface coloured with curved longitudinal rust- 

 brown streaks on the summit of the ribs. 



Long.: 51.5; diam.: max. ig"5 mm. 



Hab. : Eyres' Sand Patch, West Australia, many dead (R. H. 

 PuUeine and Jos. C. Verco). Larg's Bay, St. Vincent's Gulf, South 

 Australia (D. J. Adcock). Also found sub-fossil in dredgings from 

 Port Adelaide (Dr. Perks). 



Comparison is made by Dr. Verco with L. walke?-i mihi, also an 

 Australian species, but there is not much in common between them. 

 I have discovered three examples of Z. puUeiiiei in my collection, 

 obtained at the sale of Dr. J. C. Cox's collection in London in 1904 : 

 these, though not adult, and the largest only measuring long. 32 mm., 

 are in good condition, and recognizable. 'J'he longitudinal ribs are 

 seen conspicuously on the upper whorls, in two examples being tinged 

 with red-brown, while the longitudinal coloration (as Dr. Verco has 

 well pointed out) is continued on the body whorl, though the ribs 

 have become obsolete and evanescent. On a label with these speci- 

 mens is written, in Dr. Cox's handwriting, " Given me by Mr. 

 Pulleine, said to be from South Australia," so I conjecture these are 

 from Eyres' Sand Patch, as given above. One of them I have placed 

 in the Brit. Mus. (Nat. History). It seems a very good addition to 

 the genus, being one of the most fusoid of all in appearance. Since 

 writing the above, I have obtained another example from Mr. Sowerby 

 of very much the same dimensions. 



17. Latirus (Peristernia) rudolphi Brazier. 

 Feristernia rudolphi J. Brazier, in A. U. Henn., Proc. Linn. Soc, N. 

 S. Wales, vol. ix. , p. 186, fig. (1894). 



A very small and somewhat obscure species. The shell is rightly 

 placed in this genus, in my opinion, though I cannot discern any 

 columellar plication in any of my specimens, which I received direct 

 from Mr. Arnold Umfreville Henn, who was, I believe, its discoverer 

 in company with Mr. Brazier. The nuclear whorls are glossy, luteous, 

 and bulbous, whorls intensely impressed, subangled, ribs few, stout 

 and thick, speaking proportionately, spiral lirations also coarse and 

 conspicuous. Mouth oval, canal abbreviate. 



Long.: 1; diam.: 2 mm. 



LLab. : S. Australia.
