This fine Eunectes, the distinctive characters of which are fiilly 

 pointed out in my diagnosis above referred to, was taken by myself 

 in the pools at El Charco, in the extreme south of Grand Canary, 

 during my visit to that remote spot, mth the Rev. E,. T. Lowe, on

The 6r. striatus (remarkable, inter alia, for the deep and pale striae 

 of its elytra, greatly raised outer interstices, distinctly punctulated 

 surface, and yellow margin) is tolerably common at the Canaries, 

 thoiigh somewhat local. I have taken it in profusion, however, in 

 the pools at El Charco, in the south of Grand Canary ; as also at 

 the Agua Mansa, &c., of Tenerifte. From the latter island it has 

 likewise been communicated (together with the following two species) 

 by the Barao do Castello de Paiva. It occurs throughout central and 

 southern Europe and the north of Africa; and has been recorded 

 even from Madagascar, the Isle of France, and New Holland.
