LOCAL OBSERVATION 35 



" Decetnber \^th, 1889. 



" Did you shoot any of the Hierro ravens ? And do 

 they in any way differ from the ordinary type ? 



" I presume that Hierro is the least-known island of 

 the Canarian group ; from your account it would not be 

 a very eligible residence for any length of time, but in 

 my younger days I would have made acquaintance with 

 those big Hzards,* or known the reason why." ' 



I To E. G. B. Meade-Waldo, Esq. 



* Laceria simoni. Simony's Lizard. — A very large lizard that is 

 confined to a small rocky island — little more than a rock — off the 

 coast of Hierro. There are two of these rocks, the Zalmones, on 

 only one of which the lizard lives — viz., that farthest from the shore. 

 Owing to almost continuous surf it is rarely possible to land. This 

 lizard feeds on crabs. 



The Hierro raven i.s C. tingiianus, the Tangier raven. —
