apiculate) is occasionally marbled (rather than spotted) with 

 larger black blotches. The body, which is much roughened by 

 longitudinal sulci, has four or five (occasionally ill-defined, and 

 often subcontinent) interrupted stripes of black, which are 

 broken anteriorly into still more isolated spots or patches ; and 

 the keel extends scarcely more than a quarter of the length 

 from the tip of the tail to the hinder edge of the shield.

Likewise a European Limax, and one which occurs also in 

 the Azores. In Madeira it is widely distributed, and is found 

 occasionally around Funchal (where I have taken it at the Val), 

 at the Praia Bay, in the Curral das Freiras, &c. ; and it has 

 been met with by Mr. Watson in the north of the island. Its 

 average length is from about an inch to an inch and a half ; and 

 its colour above is a pale dirty- or brownish-yellow (slightly 

 brighter on the shield), but coarsely reticulated, or mottled, 

 except at the sides and at the edge of the foot (which are 

 immaculate), with dusky cinereous-brown. The keel, as in 

 the L. maximus, is short, — reaching scarcely a third of the 

 distance from the tip of the tail to the posterior margin of the 

 shield (which last is transversely, or subconcentrically wrinkled, 

 and appears often, when the slug is contracted, to be somewhat 

 mucronato-rotundate behind or apiculate.
