it could not have belonged to the usual I>. giganteum, as you may judge from the 

 following dimensions : 



A.ntero-posterior diameter meters. . 0.12 



Transverse " " . . 0.12 



Height of the crown " .. 0.08 



Height of the root " .. 0.14 



Distance between the hills of the crown " . . 0.05 



Thickness of the hills at their basis " .. 0.05 



These uncommon dimensions should lead us to look at these remains as belonging 

 to another species than the usual I>. giganteum, winch may be named I>. gigantissi- 

 mum. 



I went then immediately to Gaiceana for the purpose of studying the bed yield- 

 ingthe remains. Itconsists of a micaceous yellowish-gray sand, with small sheets 

 and concretions of sandstone of different sizes. This sandstone must have been 

 formed from calcareb-siliceous infiltrations evidently posterior to the imbedding of 

 the Dinotherium remains, as the tooth Avas deeply impressed in one of the concre- 

 tions, which had to be broken in order to take the molar away, and in which it left 

 a beautiful impression. The dip of the strata is low. and the strike is northwest- 

 southeast; they belong to the middle Miocene. I found there other and smaller. 

 molars, a part of the lower jaw. and the incurved symphyses, with small incisors

Twelve years later (in 1890) I became aware that at another point. /'. e., Manzati, 

 in the judet of Tutova, in a bluff which had been eroded by the rains, many hones 

 of a huge animal had been uncovered. I went there immediately, and found that 

 several persons had already taken parts of the head of a Dinotherium. The first 

 excavation which I made uncovered a portion of a jaw with two molars; but as it 

 was winter and the weather was very inclement. I postponed the investigation 

 until spring. 



The fragments which I found on this occasion are very important, viz : 



1. Tlie right branch of the lower jaw, with its five molars. This is almost com- 

 plete; only the symphysis and the ascending branch are deficient, and nevertheless 

 the length reaches 0.80m., its height at the second premolar is 0.30m., and it is 

 0.16m. thick. 



2. A portion of the left branch of the lower jaw, with the two posterior molars. 



■';. A fragment of the right branch of the upper jaw. with a portion of the palatal 

 bone and three molars.
