HARDWICKE'S SCIENCE-GOSSIP.

Hegotiate his shells with some old Indian who 

 happens to have gold or greenbacks. Americans 

 speculate in it here and there to advantage, working 

 upon the clinging love the aged savages retain for 

 the wealth of their youth. These old men save all 

 of it they can possibly acquire, and hoard it like 

 veritable misers, only on great occasions letting 

 their women folks wear any as jewelry. This hoarding 

 is not so much miserly greed, however, as it is a 

 religious notion, since to their minds the shell-money 

 is the only thing worthy to be offered upon the 

 funeral pyre of any famous chief or departed friend, 

 or sent along with their own soul into the Spirit- 

 world.

T TELIX NEMORAL1S, var. libellula, ground- 

 J. A colour yellow. 



00000 is not rare at Minster, but less common at 

 Chislehurst, 00300 is found at Dartford, Minster, 

 Ealing, and near Southall, 12345 at Minster, 

 Chislehurst, Monkton, etc., the specimen from 

 the last-named locality being unusually large. 

 I found a single specimen of 00305 in the rejecta- 

 menta of the Stour at Richborough ; it is not 

 3. common form, but has been recorded from 

 Sark and also, as var. bmguieria, from France. 

 10345 and 12045 are found near Chislehurst 

 IS. C. C), but the latter specimen is immature, 

 and would possibly have developed into 12345. 



pale yellow when the animal is extracted, may 



be called var. fallax, a sub-variety of libellula. 



I have recently had a specimen from Cabourg, in 



the north of France. 



In some specimens the black pigment is wanting 



in the shell, and the result is a pale lip and coloured 



bands. When this happens, as it sometimes does, in 



//. hortensis, the bands only are affected, the lip 



being naturally white. 



Those I have seen of this kind are : H. nemoralis, 

 var. roseozonata-albolabiata. Bands pink, lip 

 white. Blagdon, near Bristol (F. M. Hele), 

 with formulae 12345 and 023(45). H. nemoralis, 

 var. citrinozo7iata-albolabiata. Bands pale brown 

 colour, lip white. Worthing (B. M. Oakshott), 

 formula 1 2545. H. hortensis, var. roseozonata. 

 Bands pink. Acton Green and Bickley. 

 H. hortensis var. viridizonata has been found in the 

 Spanish peninsula,
