Palmipes membranaceus, Retz. Two specimens of this 
species were obtained by me while on board a trawler in the 
Moray Firth. They were brought up in the trawl-net from a 
depth of 50 to 60 fathoms. Though apparently a rare 
species on the east coast of Scotland, it is of more frequent 
occurrence on the west, especially within recent years. 
Hippasteria plana (Link.). This appears to be a rather 
common species in the Moray Firth, and is frequently 
captured by trawlers. The Moray Firth specimens differ 
a good deal from two I obtained from the Firth of Forth, 
especially in the length of the arms. (See notes on these, | 
with figures of Moray Firth and Firth of Forth specimens, in 
the Annals of Scottish Natural History for January 1892.) 
Lwidia savignyi, Audouin. This fine specimen of Lwidia 
savignyt was captured by the beam-trawl while I was on 
board a trawler working in the Moray Firth during March 
1889. The specimen remained intact, notwithstanding the 
rough usage it met with, while the trawl-net was being 
hauled on board, and while it was being removed from the 
net, which was rather an unusual circumstance, judging 
from the accounts generally given of the fragility of this 
starfish. After being removed from the net in perfect 
condition an unforunate accident happened to the specimen, 
whereby it was considerably damaged. It has seven arms, 
and measures 174 inches across the arms. Lwidia sarsii, 
Diiben and Koren, a species frequently obtained by us in the 
Firth of Forth between Fidra and the Bass Rock, is much 
smaller, and has usually only five arms. 
ichinocardium flavescens (Miiller). This species is not very 
uncommon in some parts of the Moray Firth. We have on 
one or two occasions obtained several specimens at a time in our 
small beam-trawl—especially when working off Lossiemouth. 
I have a specimen from near May Island, Firth of Forth, which 
is rather larger than those observed in the Moray Firth. 
MOLLUSCA. 
Isocardia cor (Linn.). The two fine specimens of this shell 
now exhibited were obtained by me while on board a trawler 
in the Moray Firth. They were brought up in the trawl-net.
