ochreous or even lilac tinge) being- spotted with large but un- 

 equal longitudinal patches of black, — those on the shield how- 

 ever being, most of them, both rounder, smaller, and more 

 isolated or better defined. The blotches on the body seem to 

 be brought about by four or five broken-up longitudinal stripes, — 

 which are occasionally subconfluent and suffused, but nearly 

 always more interrupted (or fragmentary) before than posteriorly. 

 It is coarsely sculptured, except on the shield, with a multitude 

 of subconfluent longitudinal grooves or (which amounts to much 

 the same thing) intervening wrinkles ; and its hinder part is 

 acutely carinated for about a third of the length from the tip of 

 the tail to the edge of the shield.

Habitat S. Miguel ; in hortis umbrosis circa Ponta Delegada 

 et Villafranca lectus. 



The European L. flavus, Linn, (or variegatus, Drap.) is 

 said by Morelet to occur 'dans les jardins ombrages,' around 

 Ponta Delgada and Villafranca, in S. Miguel, — where, as is the 

 case with it at Madeira, it has doubtless been naturalised. It is 

 a large species, varying from about an inch to nearly two inches 

 in length ; and its colour is usually of a pale dirty brownish- 

 yellow, but mottled (or coarsely reticulated) with cinereous- 

 brown, — the sides, however, and the foot, being free from 

 markings. Its keel is much abbreviated, extending from the tip 

 of the tail to about a third of the distance to the hinder edge of 

 the shield (the ground-colour of which is often a trifle paler than 

 the rest of the surface, as seen from above).
