Habitat Maderenses (Mad.), in lauretis humidis editioribus sub lapi- 

 dibus lignoque putrido rarissimum. 



Apparently peculiar to the damp sylvan districts of Madeira 

 proper, at a rather high elevation, especially in the north of the 

 island. It is however extremely rare, occurring beneath stones and 

 moist logs of wood.

Habitat Canarienses (Ten.), in sylvaticis humidis editioribus praecipue 

 degens. 



A large 'Plinthus which has been observed only at intermediate 

 and lofty elevations in Teneriffe, particularly however within the 

 sylvan districts. From about 2000 to 4000 feet above the sea is its

 Cumbre above the Agua Mansa.

Habitat Canarienses (Ten.), in montibus excelsis usque ad 8000' s. m., 

 vel etiam ultra, ascendens. 



Likewise a Teneriffan Plinthus, but one which seems to ascend to 

 a still higher altitude than the musicus or, at any rate, which 

 never descends so completely into the sylvan districts. The few
