undescribed, or manuscript speciea, or any curious varieties ; the entire

 stones on the north coast. This varies from reddish brown to pale 

 yello.vish. 



Genus Eurvlepta, Ehrenb.

Genus Planarta, Mviller, 

 P. vulgaris, Montagu, MSS. p. 230—31, t. 30, f. 7. Brown, the 

 front auricled, with numerous minute black punctures round the mar- 

 gin of the head and neck. Body oblong, slightly contracted behind 

 the head, posterior end obtuse, a dusk}' line running down the back; 

 the dots on the anterior margin extend to behind the ears in a single 

 line, seen but when the 'creature is in motion. It is an extremely 

 variable species as regards colour, varying from brown to dusky gray, 

 rufous-brown and yellowish; in some very much like P. fusca {torva, 

 Miill.), but the marginal punctures and the want of two approximate 

 eyes on the back of the head distinguish it from that species. 

 A common species in some parts of Devon in spring, in slow streams.
