Although this species may be easily recognized by its large head, small curved 

 mandibles, and short prothorax, and was briefly but recognizably described and figured 

 by Olivier (though unfortunately witliont any indication of locality), it has always been 

 misunderstood and unrecognized by authors. Burmeister is chiefly responsible for the 

 error, as he included this species also among the varieties of 0. alces. Eeiche, who 

 divided Burraeister's 0. alces into two species, sunk 0. camelus as var. minor of his 

 0. carinattis, in which he has been followed by Parry and Thomson. The priodont 

 form of this doubtful 0. carinatus, auct. (compare PI. LXXXVI. fig. G), is really very 

 like Olivier's figure, so that they might easily have been confounded at that period, 

 though the peculiar characters of 0. camelus should have made this impossible. When 

 0. camelus was once referred to C. carinatus, auct., it was long considered as such, 

 and was at length erroneously redescribed by C. O. Waterhouse, on the authority of 

 Parry and Deyrolle, as 0. gouberti. Under this name I found it in the Museum of 

 the J;irdin des Plantes and in various other European collections. A small specimen, 

 from Mindoro, in Herr van Lansberge's collection, had a narrow prothorax (fig. 8), 

 and I was involuntarily reminded of Olivier's figure. It agreed precisely with his 

 description, and when I afterwards examined the type of 0. gouberti in Major Parry's 

 collection, in company with Mr. A^'aterhouse, we were both convinced of their 

 identity, and he withdrew his name.
