The percentage of carbonate of magnesia is higher than might 

 be expected, but this may be due to some impurity in the 

 sample. Such a sand would be worthy of a thorough test as a 

 fertilizer for the acid soils which prevail in many of the basaltic 

 areas of Victoria. 



ON A NEW VARIETY (VAR. BAKERI) OF THE MARINE 

 SHELL FASCIOLARIA AUSTRALASIA, Perry. 



By J. H. Gatliff and C. J. Gabriel. 



(With two Plates.) 



(^Read before the Field Naturalists' Club of Victoria, loth June, 191 2.) 



The following is the original description in " Conchology, or 

 the Natural History of Shells," by George Perry (London, 

 igii). of Pyrula aiistralasia, pi. 54, f. 4 : — " Shell of an 

 olive green, the mouth of a dark brown, rounded, streaked 

 within. A native of New Holland and Van Diemen's Land." 

 The figure is a good one, and depicts the front asjiect of the 

 non-coronate variety of Fasciolaria, which is not common on 

 our coast. 



In 1822 Lamarck, in " Anim. Sans Vert.," vol. vii., p. 120, 

 described Fasciolaria coronata. His work had no figures ; but 

 in 1840 Reeve, in " Conchologia Iconica," vol. ix., i^l. 6, 

 ff. 14 (fl), [b], (c), {d), gave excellent figures of the mature and 

 young forms, and thus described the species : — " Shell fusi- 

 form, sometimes abbreviated, sometimes elongated, whorls 

 spirally obtusely ridged throughout, concavely slanting round 

 the upjier ]:)art, nodose at the angle, nodules rather swollen, 

 fawn or ashy-grey, encircled with two more or less obscure 

 whitish narrow zones." 



Habitat. — New Holland. 



Kiener, in " Cofpiilles Vivanlcs," vol. ii., p. i;;, jil. iv., 

 fig. 2, described and figured Fasciolaria fiisiformis, Valen- 

 ciennes. The figure resembles that given by Perry, but the 

 only longitudinal ])lirations d('i)i("(c(l ar<' on the early sjiiral
