article thus — " Je ue sache pas que cette espece ait ete decrite 

 depuis Pepoque k laquelle M. Lesson I'a denominee pour la pre- 

 miere fois; mais il me semble qu'elle peut parfaitement s^isoler 

 des especes connues de Garrulax par le blanc de la partie me- 

 diane de son abdomen." 



Describing as new a previously described species is justly 

 considered inexcusable. Yet^ in this instance, if I have done so, 

 this much may, I think, be urged in palliation : Lesson, who 

 classed it as a Tardus, merely says " tete et cou blancs." In the 

 next place, when, three years later (Bel. Voy. Zool. 1834, p. 258), 

 he founded his genus Garrulax, enumerated the species he classed 

 in it, and described the closely allied form, G. helangeri, he 

 omitted all mention of T. diardi; nor is this species to be found 

 under Garrulax in Lesson's ' Complements de Buffon,' pub- 

 lished in 1840. 



Without actual comparison of the types I cannot positively 

 affirm that the two belong to the same species. M. Pucheran does 

 not mention the existence of a crest ; and this omission, taken 

 together with the difference of oi-igin, makes it possible that the 

 Cochin-Chinese species does differ from the one inhabiting Siam.

 Sir, — An adult female Ciconia nigra, in splendid plumage, 

 was shot last week at Westacre in Norfolk. It had been living 

 at and about the river for a week or more, and might very pos- 

 sibly have stayed longer.
