OF INSECTS AND REPTILES. 371 



with three wreaths ; the operculum large, and oval ; the apex very 

 fmall, and more obtufe than the lafl; of a yellowifli-brown, 

 fometimes tinged with white, and pellucid. The horns of the 

 Umax inhabiting it are fhort, broad, and mucronated. 



46. I met with the depreffed, orbicular, frefh-ivater Cochlea, with 

 four 'wreaths (<v), in great numbers, in a fmall piece of water, 



in a meadow on the banks of North-Tyne, called Brome-Haugh, 

 near Chipchace. It hath four elegant wreaths or convolutions, of 

 a blackifh-brown. The Umax inhabiting it is of a tawney black> 

 with two reddifh horns. In warm, pleafant weather, it fails 

 about on the furface of the water with its fhell erect, very much 

 refembling the Sea-Nautilus in its motion. It is the only one of the 

 aquatic Cochlea that will yield a fluid on an injection of a grain of 

 fait, pepper, or ginger, into its mouth, or by laceration, or pierc- 

 ing. The fluid it gives is a fine fcarlet, but of fo fugitive a na- 

 ture, that no acid or aftringent has hitherto been found fufficient 

 to preferve the elegancy of its tincl, and from turning to an un- 

 pleafant rufty hue. 



Naked amphibeous reptiles, whofe lungs are fo formed that 

 they can live for fome time under water, as well as upon land, 

 are lefs common with us than in the fouthern counties. 



47. The Viper (-w) is fometimes obferved at the roots of trees 

 in woods, and among rocks on warm heaths, and under hedges.
