TONNA TETltACOTULA, sp. UOV. 



(Plates xlii.-xliii., figs. 4-5.) 



Shell large, ovate-globose, rather solid. Spire conical, rather elevated. 

 Whorls five, plus a three-whorled horny protocouch ; after the second 

 whorl, the suture runs in a continuously deepening trench. 



Colmir. — Ground colour white to pale orange, often uniform but 

 sometimes three spiral bands of hazel brown are more or less developed, 

 the uppermost sometimes ascending the spire, each may cover a rib and 

 one or both of the adjoining furrows, they are apt to be evanescent on the 

 back of the last Avhorl and they may be entirely absent ; when the apex is 

 worn it appears blackish brown. The interior is white stained with 

 cinnamon. The surface of the shell is glossy, the whole corded with 

 nineteen to twenty-one (not counting the interstitial lublets) rather elevated 

 ribs, four or five of which ascend the spire ; those on the base are narrow 

 and closer than the others ; on the fourth and fifth whorls an interstitial 

 riblet appears in each main groove of the upper half of the shell. 



Aperture ample, semilunate ; outer lip simple, inner lip a smeai' of 

 callus. Throat corrugated by the external imprint of the ribs. Columella 

 vertical, smooth, reflected over a nai-i'ow spiral umbilicus. Snout twisted, 

 spiiallv grooved and decussated by growth stria*. Canal notch not 

 ]n'odnced. 



Height (of type;, 198 mm., major diametei-, 150 mm., minor diameter, 

 117 mm. Another specimen, 187 ; 150; 105 mm. Weight eight ounces, 

 ca])acity two pints. 



This species seems to be a i*epresentative of 7'. /Ksrinfa, f i imi which 

 7'. tt'traciitiihi differs by much larger size, more globose form and by the 

 riblet which runs between the major ribs on the shoulder of the shell. 

 Besides in 7'. fnsrintn, the lip is sharply reflected and denticulated and the 

 first adult whorl has a reticulated sculpture caused by radiating threads 

 absent in 7'. fpfrarotxlu. 



Inr. — Off Gi-een Cape, New South Wales, 40 to 80 fathoms.
