Neiv Species of Victorian Mollusca. 183 



Haliotis granti, sp. nov. (PL X.), 



Shell strong, l)roadly ovate. 



Dofsal aspect. — Spiral portion of the whorls well detined and 

 elevated. Body whorl somewhat flatly convex, and from the 

 outer lip, for about one-half of the whorl, radiately ruggedly 

 ridged ; ridges following the contour of the lip, and being six or 

 seven in number ; these are crossed by numerous irregular, 

 comparatively fine, spiral ridges, which are closely scaled. 

 Perforations strongly produced, tubiform ; five open, and another 

 half formed on the lip. The perforated ridge is followed 

 outwai'dly by a broad concave area, then there is a well defined 

 ridge, having on its under side two minor ridges ; base sharply 

 angled. 



The spire is white, with irregular radiating bands of brown, 

 with green shading, which gradually coalesce ; the outer portion 

 of the body whorl being of a uniform dull olive brown. 



Basal aspect. — -The inner lip is somewhat broad and concave ; 

 and from about its centre to the outward termination gradually 

 tapers off in width. 



The iridescence of the nacre is richly tinted, the predominating 

 colours being rose and green. 



Dimensions. — Greatest diameter, 140 mm.; smallest diameter, 

 110 mm.; altitude, 43 mm. 



Locality. — Shoreham Beach, Western Port (J. H. GatlifF). 



Observatcons. — This species in broadness of form and tubular 

 production of the perforations is allied to H. cunninghamii. Gray, 

 but is more rugged in sculpture, excepting in the spiral ridges, 

 which are finer. It is nearly related to H. nae\'0sa, Martyn, 

 but is much broader, the spiral whorls are more elevated, the 

 body whorl flatter and the projections of the perforations are 

 much larger ; the base of the inner lip tapers more gradually, 

 and it is broader from the columella outwards ; and the coil of 

 the shell is more circular ; the iridescent coloration is very 

 much richer. 



Type in Mr. Gatliff's collection. 



We have much pleasure in naming this shell after Mr. F. E. 

 Grant, who has assisted us in our work by his skilful drawings 

 of many of our new species.
