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 localities 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. 



•' Percheron gives Guerin-Meneville as the author of this and other names, without giving a reference. 

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

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

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

 "Cette espC-ce a ete dccouverte par M. Ad. Delessert sur le plateau des Neelgheries. Nous I'avons 

 communique a M. Percheron, qui I'a fait eutrer en notre nom, dans sa Moiiographie . ..." 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.
