considerable angle from the central spire ; this movement, in consequence 

 of the size of the animal itself, caused the outer wall of the body-whorl 

 also to leave its normal course and to bulge out to the extent of twice its 

 usual diameter. Judging by the appearance of the new departure, the 

 animal was healthy and vigorous, and had it been allowed to grow to its 

 full size would have evidently developed into a most remarkable specimen, 

 the extraneous cause of its curious growth having apparently disappeared. 

 The shell is altogether an exceedingly interesting one. —Edward Lovett 

 (Addiscombe, Croydon). 



CRUSTACEA. 



Scyllarus arctus at the Land's End. — I have received from Mr. 

 Stephen Bond, of Sennen Cove, a specimen of Scyllarus arctus, which was 

 captured off the Land's End. It is a small specimen with nothing special 

 to note about it except that it comes from a new locality. — Thomas 

 Cornish (Penzance). 



[This more or less uncommon species is figured in ' The Zoologist' for 

 1879, p. 473.— Ed.] 



Abnormal Colour of Common Lobster. — Messrs. Sinel & Co., marine 

 zoologists, of Jersey, have sent me a specimen of the Common Lobster, 

 Homarus marinus, the colour of which is a pale lavender ; upon the back of 

 the cephalo-thorax, however, there is a patch of mauve, and the large claws 

 are of a bright pale blue ; the usual mottled marking of the sides of the 

 thorax are rather indistinct. This specimen reached me alive, so that I can 

 vouch for the colours being quite natural. It was a full-grown female, 

 carrying ova which was nearly mature. I remember having observed a 

 mottled variety, and another which was a dull pink, both alive at the time 

 I noted them ; the pale blue variety is, however, less rare, I believe, though 

 my specimen is particularly beautiful in tint. — Edward Lovett (Addis- 

 combe, Croydon). 



SCIENTIFIC SOCIETIES. 



Linnean Society of London. 



November 6, 1884. — Sir John Lubbock, Bart., M.P., F.R.S., President,

A letter was read intimating that the late President, Mr. George
