in abundance, but also to meet with this little Helix and the 

 Lucasius which is here described. My rediscovery of the 

 H. tiarella ally led to its description by Mr. Johnson under 

 the name Helix Watsoni. 



Metoponorihus sexfasciatus, Budde-Lund. 



I procured two specimens, which Dollfus, from their im- 

 perfect condition, doubtfully refers to this species, which had 

 been previously found in Madeira by Dr. H. Bronniche. 



Porcellio maculipes, Budde-Lund. 



This has been taken twice in Madeira, and is unknown 

 elsewhere. I did not meet with it. 



Porcellio Icevis, Latreille. 



Very abundant in the neighbourhood of Funchal, especially 

 in gardens and among bananas. 



Porcellio dilatatus, Brandt. 



Specimens are in Dollfus's collection which were found by 

 Dr. Nodier. 



Eluma purpurascens, Budde-Lund. 



This species is remarkable on account of its simple eye- 

 lenses. I met with it up to heights of between 2000 and 

 iiOOO feet. Its range extends throughout the Madeiran 

 province, it having been found both in the Canaries and 

 Azores. It has also been met with in Portugal and Spain, 

 and at Charente, France ; but of this last locality Dollfus 

 writes : — " ou il a 6t4> certainement introduit." 



Armadillidium vulgare, Latreille. 

 Very abundant round Funchal. 



Armadillidium tigris, Budde-Lund. 



Taken by Metschnikoff in Madeira and not known else- 

 where (Budde-Lund). 



Armadillidium granulatum, Brandt. 



A specimen taken by Dr. H. Bronniche (Budde-Lund).
