THE ENTOMOLOGIST. 268 
portion of 1857; Mr. Walker visiting Calais, Rouen, Paris, 
Strasbourg, Baden-Baden, Heidelberg, Wiesbaden, Frank- 
fort, Mayence, Cologne, Brussels, Aix-la-Chapelle, and 
Antwerp. During the journey he collected in the Black 
Forest; and this is the only scene of his scientific labours, 
during the tour, of which I have any intelligence. 
The summer of 1860 was devoted to a thorough exploration 
of the Channel Islands. Dr. Bowerbank was his companion 
during a portion of the time; and, as a consequence, the 
sponges of these islands, were a main object of research,— 
the Gouliot caves in Sark, so celebrated for their marine 
productions,—were a great attraction to both naturalists. 
In 1861 Mr. Walker’s excursions were chiefly confined to 
North Devon; he visited Linton, Clovelly, Ilfracombe, Bide- 
ford, and Barnstaple: and now his attention seems to have 
been again chiefly occupied with Lepidoptera, at the scarcity 
of which he was greatly disappointed, having expected, from 
the extensive woods, to have found moths particularly 
abundant. 
In 1863 he toured the English lakes; and, in the spring of 
1865, North Wales and Ireland; and in the autumn he again 
visited Paris, Geneva, Lucerne, Interlachen, and Altdorf, 
ascending the Righi, Mont Pilatus and the Miirren, and 
proceeding to Kandersteg, the Oeschinen See, and the 
Gemmi Pass. . 
In 1867 we find him again in France and Switzerland, 
ascending the Col de Voza, and examining the Jardin of the 
Mer de Glace; thence over the Téte Noir to Martigny, Sion, 
and the Great St. Bernard; returning by St. Maurice and the 
Villeneuve to Geneva. 
In 1869 he made the tour of the Isle of Man, and returned 
by Holyhead ; in 1870 he paid another visit to Llanberis, as 
well as to all the more beautiful scenery in North Wales, 
crossing over to Ireland, and touring that island from south 
to north; and in 1871 he examined entomologically the Scilly 
Islands, and the districts of the Lizard and the Land’s End. 
In 1872 he turned his attention to Italy, visiting Rome, 
Pisa, Lucca, Florence, Naples, Sorrento, Capri, Milan, and 
Venice, as well as the Lakes of Como and Maggiore. 
And, finally, in the present year, he had again proceeded 
as far as Aberystwith, on his way to Ireland, when his 
intention was frustrated by illness, which terminated fatally
