A REVIEW OF VOLUTIDAE 



conspeclflc. Cotton and Godfrey used Cox's 

 name and placed the species under Alcithoe , 

 but the typical species of that genus Is 

 smaller, the shell more solid, the outer 

 lip strong, and has a very small, persist- 

 ent apex, a character of great importance. 

 Compared with the Rottnest shell, the pres- 

 ent species is comparatively narrower, the 

 nodules stronger, and it should be kept 

 separate until more Western shells are 

 available. These may be related to such 

 fossils as Valuta ai ticostata Tate and V. 

 heptaional is Tate.

Alt. 125-163 mm., holotype 125 x 80 



mm. 



Hab. Cox's type locality: Rottnest Island, 

 Western Australia, dead shell from an 

 excavation; Verco's locality: 77-105 

 fathoms 90 miles West of the meridian 

 of Eucla, Great Australian Bight; New- 

 land Head, rare. 



Shell rather large, fusiformly 

 ovate, rather thin, of a uniformly yellow 

 cream color, without any trace of color 

 markings; whorls? (spire broken); body- 

 whorl ovate, rather inflated, exhibiting at 

 the upper part eleven moderately prominent 

 rounded plicae, which are nodose about half 

 an inch from the suture, and gradually be- 

 come obsolete about the middle of the whorl; 

 above the tubercles, which are dark colored, 

 the whorl is slightly concave, so that a 

 rounded angulation is formed by the tuber- 

 cular prominences; the surface exhibits 

 fine lines of growth, which are most dis- 

 tinct near the suture and between the pli- 

 cae; columellar folds three in number, well 

 defined, but not conspicuously prominent, 

 the anterior forming the lower columellar 

 margin; outer lip not thickened (immature) 



showing only a broad shallow anterior notch 

 or sinus. Length (of last two whorls) I25, 

 diam. 80 mm. 



The holotype, long a unique speci- 

 men, was procured from excavations raised 

 during the construction of a pier on Rott- 

 nest Island, twelve miles northwest of 

 Fremantle. Sir Verco's figure shows a 

 specimen which also lacks the nucleus and 

 has an equally thin lip, the color being 

 apparently iron-rust brown.
