Fossil in the Arctic shell-clay, Fife (Rev. Thos. Brown). 
Living specimens from the Porcupine dredgings in very 
deep water (2090 and 2435 f) were of a reddish-brown 
colour, and enclosed in a membranous case. The genus 
Deni ydium proposed by Prof. Torell for this species seems 
o be unnecessary; at least I cannot detect any characters 
" distinguish it generically from Mytilus phaseolinus. The 
name Dacrydium has been long used in botany.
