It will form a separate genus very distinct from Rhomhognathus, to 

 be characterized as follows ■.—Simognatlms, g. u. Maxillary palpi 

 dorsal, arranged as in Lejptognathus ; rostrum short and broad. Type 

 PachygnatJius sculptus, Brady. This genus is to Rhomhognathus 

 what Lcptognathus is to Halacarus. 



Another type characterized by Dr. Lohmann, although not found 

 in the Baltic, is the genus Agaue. It is a southern type which 

 makes its appearance first in the Bay of Biscay {Agaue hrevipalpus, 

 gp. n., from the oyster-beds of Arcachon). In the Mediterranean 

 this type seems to replace the genus Halacarus, which there has only 

 two species {H. oculatus and //. levipes, sp. n.), while the genus 

 Agaue has three species, namely A. hirsuta, sp. n., a robust type of 

 considerable size (0-75 millim.), A. microrhyncJia, sp. n., and A. 

 hrevipalpus, which is identical with the species from Arcachon. 

 These three species occur upon the Corsican moss (Spha'rococcus 

 hehninthocorton) and the Corallines which live in the same localities,

To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — 



I enclose you the description of a distinctly new species of Chat 

 which I discovered in the island of Fuerteventura in March 1888. 

 This year I spent some weeks in the island and procured several 

 specimens, also its nest and eggs ; these also are quite distinct, as 

 are the breeding-habits of the bird. 



Yours faithfully, 



E. G. Meade-Waldo,
