tuous, filiform vas deferens or epididymis, like that of Buc- 
cinum undatum (our Murex undatus) ; it is at least 24 mches 
long, or three times the length of the shell. The tongue is 
also of extraordinary length, flat, strap-shaped, and without a 
spinous armature. There is a single branchial plume in the 
usual place ; it is small, narrow, of twelve to fifteen short coarse 
strands, with an arterial or branchial vein in the centre; 
indeed we are not quite sure that the plume is not double; 
the colour is pale drab. We have not observed an incipient 
fold of the mantle, but whether it be there or not, we have 
sufficient evidence of an approach to the Muricidal tribes ; 
and after we have given some notes on Scalaria, Llanthina, 
Natica, Lamellaria, and Velutina, our scheme of natural 
order from the Bullide to the Muricidal families will be 
sufficiently developed. 
It is scarcely doubtful that the H#. nitida is a mere variety 
of the type, EL. polita, and the two varieties of H. distorta are 
the young. The £. polita is lively, not at all shy, and inha- 
bits the coralline zone at Exmouth in abundance. The other 
acknowledged British species are the KH. subulata and LE. bi- 
lineata, but their distinctness admits of doubt.

We have considered this arcuated shell as the young of 
E. polita, but having obtained some living examples, we offer 
a description, that naturalists may judge for themselves. 
Animal inhabiting a glabrous, transparent, arcuated or 
distorted shell of 8-10 volutions ; the ground colour is flake 
or pure white, and the anterior part of the body is marked 
irregularly with 15-20 distinct minute red dots. The liver in 
our various examples, as seen through the shell, is yellow, red, 
pink, light green and white, and the same variations, with the 
addition of purple, occur in E. polita. The tentacula are 
pure or frosted white, and appear proportionately rather 
longer, flatter and less conical, than in LE. polita ; their termini 
have the characteristic flake-white tips or minute lobes of
