or four very small and slightly developed spines on the outer side.

Messrs. Parry and van Lansberge and in the Paris Museum.

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 without 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. Reiche, who 
divided Burmeister’s 0. alces into two species, sunk 0. camelus as var. minor of his 
O. carinatus, in which he has been followed by Parry and Thomson. The priodont 
form of this doubtful 0. carinatus, auct. (compare Pl. LXXXVLI. fig. 6), is really very 
like Olivier’s figure, so that they might easily have been confounded at that period, 
though the peculiar characters of O. cumelus should have made this impossible. When 
O. camelus was once referred to-O. 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 Jardin 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. Waterhouse, we were both convinced of their 
identity, and he withdrew his name.
