SUTER : NEW ZEALAND TROCHID.l':. 271 



According: to Pilsbiy, the T.p^qnllus, Gould, is undoiibtedly a species 

 from the west coast of North America, and belongs to the genus 

 Margarita. 



Shell conical, imperforate, shining, solid, of very variable colour 

 and markings. Specimens from the North Island are cinereous or 

 white, with broad red spots on the upper whorls and below the suture 

 on the last whorl, the remainder being adorned with red spots ; some- 

 times the whole shell is pink, with broad obliqiic white bands running- 

 down the two last whorls to the periphery. The South Island 

 specimens are much duller, the first three or four whorls are mottled 

 with dark-grey and purple, whilst near the sutures white spots are 

 found at regular intervals, 6-7 on a whorl, forming longitiulinal bands

on the second and third whorl. The last whorls are dark-purple or 

 greenish-brown, with longitudinal, narrow streaks of yellow or 

 yellowish- grey. The whorls, 5-6, are slightly convex, mostly a little 

 shouldered, the last whorl angled at the periphery ; all the whorls arc 

 cingulate, the cinguli being broad and flat, and the interstices narrow, 

 5-6 on the penultimate whorl, about 1 3 on the body-whorl, crosscid by 

 fine obli(iue striae of growth. Below the sutures and on the periphery 

 of the last whorl two cinguli are usually fused together ; base convex ; 

 sutures impressed. Aperture oblique, subrhomboidal ; outer lip thick, 

 white inside, columella oblique, arched, slightly straightened in the 

 middle, its reflection covering the umbilicus entirely, or leaving only 

 a very narrow fissure. Alt. 8, diam. 7 mm. 



Hdb. — Heads of Manukau Harbour ; Lyttclton ; Banks' Peninsula 

 to Duuedin. On seaweeds ; not common. 



Captain Hutton rightly remarks that this is a very vaiiable shell. 

 The character and number of the cinguli I found to be constant. 

 North Island specimens especially are lovely shells; hardly two are 

 alike in colour and pattei'u.
