Odontolahis Celehensis has been imperfectly known to 

 Dr. Leuthner ; the female , which remained unknown to 

 him , has been captured in South Celebes by Mr. Ribbe 

 and was shortly afterwards described by Mr. Albers. Be- 

 sides specimens obtained by this collector I received also 

 a teledont Odontolabis captured at Tomboegoe (East Cele- 

 bes) by his companion Mr. Kuhn. At first this specimen 

 puzzled me very much , but after a most careful examination 

 I was happy enough to recognize it to be the true teledont 

 form of 0. Celehensis. Now I do not well understand why 

 Dr. Leuthner , who has called the largest form of 0. Dal- 

 mani Hope known to him, the forma amphiodonta, 

 has taken without any hesitation the same development of 0. 

 Celehensis with mandibles exactly similar to those of Dal- 

 mani for the forma teledont a. The knowledge of the 

 true teledont form proves that the teledont form of Leuthner 

 is the large amphiodont form and moreover that 0. Cele- 

 hensis is a very distinct species and not at all, as sug- 

 gested by Dr. Leuthner »a well-marked local form of 0. 

 hellicosus'\ The teledont form of Celehensis is just inter- 

 mediate between that of hellicosus Cast, and alces F. ; the 

 mandibles with basal teeth placing it near hellicosus, whilst 

 the downwards curved mandibles and the head with rai- 

 sed crest approach it towards alces.
