Habitat Maderenses (Mad.), in cisterna quadam supra urbem Fun- 

 chalensem a Dom. Bewicke parcissime captus. 



Detected by the late Mr. Bewicke near Funchal in Madeira proper, 

 and apparently quite as rare in the Madeiran Group as the preceding 

 species is at the Canaries. Although, I believe, truly distinct from it, 

 they are both of them closely allied to the widely spread E. sticticus.

This common European Gyrinus is widely spread over the Cana-
