LEEDS CONCHOLOGISTS AND THE WAR. 



Of the Leeds Conchological Club, which consists of about a 

 score of members, three are, or have been, in the Army on active 

 service or in training — Private Walter Withell, Leeds, 15th 

 Battalion West Yorkshire Regiment, was wounded and dis- 

 abled on the first day of the Battle of the Somme, when he 

 was in the leading company of the leading battalion of his 

 division. Has collected shells in Egypt and at Serre, in France, 

 as well as in camp in Wiltshire, and in hospital at Dorchester 

 after his war services. Second Lieutenant C. Theodore Cribb, 

 of Shipley, was in the Army Service Corps as Andriencq in the 

 Dep. Pas de Calais ; made large collections of the shells of 

 that district. His list will appear in the Journal of Con- 

 chology and will be a notable contribution to the malacology 

 of France. He is now in Sussex, training for the Royal Field 

 Artillery, is using his spare moments in working at Sussex 

 mollusca, and has already sent an addition to the recorded 

 fauna. 



IRISH SHELLS. 



Signaller Ernest Stainton, B.Sc, of Doncaster, of the 2nd 

 Sixth Battalion Scottish Rifles, is in training at Kilworth Camp, 

 near Fermoy, County Cork. He is at present utilizing his 

 spare time to great advantage, investigating the mollusca of 

 the Fermoy district, and has already sent a large number to 

 Mr. W. Denison Roebuck for record, who will probably draw 

 up and publish a report of his work for The Irish Naturalist. 

 This is not a bad record for a little society, when all its service 

 members do good work and utilize the scanty opportunities 

 they have. 



MOSQUITOES, BUGS AND SPIDERS. 



The British Museum (Natural History) has recently issued 

 three of its ' Economic Series ' of publications, which are 

 especially valuable at the present time. One, dealing with 

 ' Mosquitoes and their Relation to Disease : their Life History, 

 Habits and Control,' is by F. W. Edwards. Another, by 

 B. F. Cummings, refers to ' The Bed-Bug : its Habits and 

 Life-History and how to deal with it.' Like the preceding, 

 this is sold at one penny. A more substantial pamphlet 

 describes ' Species of Arachnida and Myriopoda (Scorpions,
