Burmeister' S description of this species is not altogether in agreement with my 

 observations. Neither in this, nor in either of the other known species of Taeniocerus , 



' Borneo is the locality given by Kaup, who mentions 19 specimens in the British Museum. Lewis, 

 however, speaks of "A. platypus, Kaup, from Tibet, of which there is a series in the National 

 Collection " of Britain. The other locaHties given here are those of specimens in Berlin, which I did not 

 see in time to include any account of them in part 4 of this paper. 



* This record is based on a pair of specimens in the Oxford Museum. 



2 Percheron gives Guérin-Méneville as the author of this and other names, without giving a reference. 

 In the case of Passalus {Episphenus) neelgherriensis, where he gives as reference " Rev. Zool.", a search 

 through all possible volumes of that publication has failed to reveal any mention of the species ; and as 

 Guérin-Méneville himself wrote (1843, p. 50) two years after the publication of Percheron's paper 

 "Cette espèce a été découverte par M. Ad. Delessert sur le plateau des Neelgheries. Nous l'avons 

 communiqué à M. Percheron, qui l'a fait entrer en notre nom, dans sa Monographie . ..." it is 

 evident that Percheron was the first to publish both the name and the description. Consequently in all 

 such cases I have attributed the species to him, giving in the synonymy, however, also the name of 

 the author to whom he attributed it.
