Habitat. The type, with five others from Frederick 

 Henry Bay, two others from Thonin Bay, East Cbast. 

 All the specimens have been taken from the roots of the 

 giant kelp and have much the appearance of young shells. 



It resembles X. ler/randi, Beddome, more than any 

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

 much more strongl}^ sculptured, and has many more spirals.

POLINICES CATENOIDES, sp. nov. 



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

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

 very large, rounded, with a slight depression below the 

 suture. AiDerture roundly lunate, rather produced in 

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

 partly co'vering the umbilicus, and developing into a pad 

 where it joins the lip abovei; the callusi has a distinct 

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

 which latter is of moderate size, deep and perspective. 

 The colour appears to be yellowish-brown, paler 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 15 mm. 



Type with 10 others, mostly small, froiU abont 60 

 fathoms South of Port Arthur and one from 100 fathoms 

 East of Cape Pillar. 



This species is remarkably like P. catena, da Costa, 

 from Northern Europe, so much so, that it is at first diffi- 

 cult to see any differences. 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 

 colour is .different. Compared with F. nulacoglosm, Pils. 

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

 pad over the umbilicus, besides being much smaller. I 

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

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

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

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

 show traces of coloration as above described. It is jdos- 

 sible it reaches a considerably larger size, as none of mine 

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

 from about 50 to 100 fathoms.
