Habitat. The type, with five others from Frederick 

 Henrv Bay, two others from Thouin Bay, East Ooast. 

 All the specimens have been taken from the roots of the 

 giant kelp and have much the appearance of young shells. 



It resembles X. /rf/raiif/i, Beddonie, more than any 

 other, but is entirely distinct from that species, which is 

 much more strongly sculptitred, and has many move spirals.

POLINICES CATENOIDES, SJO. UOV. 



Shell of moderate size, rotund, with a small but sharp 

 spire; umbilicate. Whorls nve, rapidly increasing, the last 

 very large, rounded, with a slight depression below the 

 suture. Aperture roundly lunate, rather produced in 

 front, lip thin. Columella a little coiuave, with a callus 

 partlv covering the umbilicus, and developing into a pad 

 where it joins the lip above ; the calluii has a distinct 

 groove crossing it, at the upper edge of the umbilicus, 

 which latter is of moderate size, deep and perspective. 

 Tha colour appears to be yellowish-brown, pahr below the 

 suture, and on the base, and there are indications of chest- 

 nut flames crossing the sutural band, and patches of the 

 same colour on the bodv whorl. Diameter and height, 

 each lo mm. 



Typo with 10 othcr<, mostly small, froji about 60 

 fathoms South of Port Arthur and one from 100 fathoms 

 East of Cape Pillar. 



This species is reniarkaVjly like /'. mtriin, da Costa, 

 from Northern Europe, sc much ^o, that it is at first diffi- 

 cult to se3 anv diftcrcnces. However, the umbilicus is 

 rather smaller, and the front of the columella more pro- 

 duced ; it is rather broader, has a depression below the 

 suture, a furrow on the columella, and probably the 

 (flour is different. Compared with /'. nitfttn/i/hisya, Pils. 

 and Van., it is a mucn rounder shell, and lacks the heavy 

 pad over the umbilicu?, besides bting rniich smaller. I 

 have known this species for a considerable time, but hesi- 

 tated to describe it, hoping for better examples ; such, 

 however, have not yet ccme to hand. All my specimens 

 are "dead, and most have lost their colour, but some 

 i^how traces of coloration as above described. It is pos- 

 i^ible it reaches a considerably larger size, as none of mine 

 appear to be quite adult. Its station would apnear to be 

 fi-oni about .50 to 100 fathoms.
