( Taken as read before the Royal Microscopical Society, June 5, 1872.) 
Plates XXV., XXVI , and XXVII. 
OctopopiDjE. Octopus, No. 18. — Not common; seems identical 
with Oct. vulgaris. 
Palate, formula, 3.1.3. The teeth do not agree with those 
drawn in Mr. Hogg’s paper, ‘ M. M. J.,’ March, 1868. The central 
tooth has two lateral denticles. 1st lateral is much smaller. The 
3rd is not so large. The bases of the teeth are also different. 
Sepiatle. Sepia, No. 43. — Common. Shell and animal seem 
identical with Sepia officinalis. 
Palate, 3.1.3. The teeth are all very much alike. The 3rd 
lateral wants the expanded base which Mr. Hogg gives it, and in

Sir, — Having made a collection of the palates of Mollusca while resident on 
the sea-side of our harbour, and having been in correspondence with Mr. S. J. 
Mclntire on the subject, at his suggestion I beg to forward you by this mail (as 
a registered packet) drawings of the same, together with some notes on them, 
that may be of interest, and deemed suitable for the pages of the ‘ Monthly 
Microscopical Journal.’ The drawings are a first attempt with a pen, and I trust 
they will be found capable of reproduction without much difficulty. 
I have made the notes as concise as possible, perhaps too much so, and have 
arranged them according to the Families, as far as I am able. I have throughout 
retained the numbers that I gave them in the order of collection, as my slides and 
shells are so numbered ; but of course if they are inserted in the Journal it will be 
better to substitute those of the figures of the plates in the order in which they 
may appear. I will forward the shells to you, and will advise you of the means 
by which I do so before closing this, hoping you will be enabled to place them in 
the hands of some one who will be kind enough to name them correctly, and 
which names may I ask you to insert in their places, and to send me a list witli 
my numbers added, so that I may with certainty know the proper names. 
Although I have not drawn the palates, I send also some fresh-water shells, of 
which No. 48 is one that I can find no genus in Woodward that I can include it
