OBSERVATIONS.
gating anything at all uncommon. Horribly few of the English provincial museums possess really good collections of the smaller invertebrata : e.g. not one in Suffolk could show you an example of the Bed Bug (Cimex lectularius, Linn.). It was easy, therefore, while cohecting Pliocene Fossils here, and both Eocene and Oligocene ones elsewhere, this year, in pursuance of our article upon another page, to put aside a bycollection. In the case of Fossil Shells the word greed cannot exist, for the strata go back into the earth for untold distances and you not infrequently gaze at a cliff-face thirty feet in height that is füll of them ! The result was that Mr. Elliott, Mr. Doughty, Mr. Engleheart, Mr. Fowler and ourseif have presented no less than 1697 named specimens to the St. Edmundsbury, Thetford and Ipswich museums from the Suffolk Naturalists' Society. Members as a whole would do well to cast their bread upon the waters in this way. MOLLUSCA.—The Fresh-water Snail, Aplexa (Flem. Moll. 1828 nec Aplexus, Gray, Moll. 1840 non Aplecta, Guen. Lepidoptera 1837) hypnorum, Linn., is a very local species in eastern Suffolk and apparently unnoticed in western. Mr. Edward A. Ellis of the Norwich Museum took two or three dead shells at the Latimer Dam in Kessingland during November 1925, but nous autres have searched there in vain. The only other Mollusc of note recorded in the local Press this year is a young Octopus (presumably Sepia officinalis), captured on 18th June while trawling in Holbrook Bay of the River Stour by H. and W. Quantrill, at whose home in Lower Holbrook it was later exhibited. This Cephalopod, though stated to be of rare occurrence there, has been observed from Felixstow to Yarmouth. To this kind of free-swimmer the condition of the bottom seems of small account; but Mr. Doughty is doubtless correct in saying (in lit. 19th Feb., 1930) that the probable scarcity of the larger CRUSTACEA upon this coast is due to the fact that " our sea-bed is all so bare of seaweed and so shifting in its character that such things will not live where they are continually being turned out of house and home, and there are no cosey rock-crannies or holes for them to shelter in." Our own experience goes to show that such is likely to be no less true of smaller Crustacea also. ARACHNIBA.—Last year we announced a False-scorpion seu Chelifer new to Suffolk ; this year we can bring forward a second, equally novel to us, in the species Chthonius orthodactylus, Leach. One example had fallen into a sand-pit at Gisleham on 6th August 1930, and three more were found in the same Situation on 15th September, showing it probably not rare in that district : when alarmed, the creature springs backwards with
