altitudes. In the Madeiran Group it is extremely rare, occurring 

 however hoth in Madeira proper and Porto Santo ; but at the Ca- 

 naries where it has been taken in Grand Canary, Teneriffe, Gomera, 

 and Palma it is less scarce (being in some places indeed almost 

 common).

This most interesting little Aepys has been observed only (in two 

 localities) along the edges of the sea-shore in Madeira proper ; and 

 it must therefore be regarded as extremely rare, even though by no 

 means uncommon in the few spots which harbour it. It was detected 

 by myself (during December 1858) in the crevices of a low muddy 

 bank, facing the beach, which terminates the marshy ground at the 

 mouth of the Sao Vicente ravine, in the north of the island, as also 

 from beneath the shingle and stones which must have been submerged 

 at high tides. And the late Mr. Bewicke subsequently obtained it 

 on the opposite side of the island, in the vicinity of Funchal " in 

 wet sea-sand near the Gorgulho, below high-water mark." From 

 which it will be gathered that its habits are precisely similar to those 

 of its more northern ally, the A. marinus (from which, however, 

 specifically, it is most distinct).

Detected hitherto only in Teneriffe and Gomera, of the Canarian 

 Group, in the former of which it was taken by myself (at the edges 

 of a small pool near S ta Cruz), and in the latter (during the summer 

 of 1864) by the Messrs. Crotch. Possibly it may be merely a dark
