Mollusks — Insects.

and Caliban suddenly vanishes in the bush, but speedily returns both 

 hands filled with beetles. Thus we are mutually understood by the 

 use of three words only. 



From my elevated position in the fir-clearing I now look down upon 

 the land-locked harbour. To the right is Desima and to the left is 

 Pappenberg, down whose steep sides it is said fifteen thousand Chris- 

 tians were once precipitated. All around green-wooded hills, check- 

 ered with fields of yellow wheat, rise up from the water's edge ; the 

 dark smooth surface of the harbour is dotted with strange-fashioned 

 craft ; the monotonous loud cries of the boatmen, " ush-shia, ush-shia," 

 faintly reach my ear, as bending to their powerful sculls these semi- 

 nude Athletae urge their sharp-pro wed boats swiftly through the water. 

 Parties of women sing gaily as they voyage from shore to shore, fishing 

 boats are casting their nets, clean unpainted trading junks spread their 

 white sails to the favouring breeze, and the dark banner-bearing barge 

 of the Japanese Governor, propelled by many oars, and looking like a 

 galley of old Rome, moves with slow and solemn state to the sound of 

 music.

Cyclas pallida, Gray : Sphcerium ovale, Ferussac. — Mr. Jeffreys, in his excellent 

 and interesting * Manual of the British Mollusca,' at page 9, says, " Mr. Daniel found 

 this species in the Grand Surrey Canal," &c. It was in the year 1851 I found a single 

 example, in company with C. rivicola and C. cornea : it was my first year of entering 

 on the study of Conchology, and I was in London for only a few days ; and after that 

 a long absence from England prevented my again searching for it. However, on my 

 return this summer I have had the satisfaction of finding it in great abundance in the 

 same and another near locality, always in company with C. caliculata, var. Broctonia- 

 num. They are precisely similar to those from the Regent's Canal, but a little paler 

 and brighter than from the Leeds and Liverpool Canal. — John E. Daniel ; 10, Trigon 

 Terrace, Clapham Road, S., November 11, 1862. 



Mutation of Species. — Most of your readers will have perused the admirable paper 

 of Mr. Edwin Brown (Zool. 8249) on the mutability of species. This subject has so 

 much interest for me that I hope I may be pardoned for retouching a subject already 

 so ably handled. During the spring of this year, which was spent in an entomolo- 

 gical excursion to the Canary Islands, I have captured about 340 species of Coleoptera, 

 120 species of Hemiptera, and 130 species of Lepidoptera. Of course, since my 

 return my attention has been largely given to the arrangement and nomenclature of 

 these specimens. Many of them differ very slightly from European forms, e.g., 

 Dasytes subaeneus, WolL, and D. flavipes, Fab. In these and analogous cases may
