large canine which measures 38 mm. in length by about 30 mm. 

 in width. Behind the canine on the left side are portions of 

 three small molars. There have certainly been four, and vei-y 

 probably there have been five. Those preserved are relatively 

 small. The second measures about tlie base of tlie crown 

 8 mm. X 7 mm. These molars are ari'ange<l as shown in text- 

 lig. 17. On the right side the molar arrangement is diflerent. 

 There is preserved only one molar, which is close to the canine, 

 and this is larger than any of the molars of the left side. The 

 section of the tooth measures 11 mm.xlO mm. Possibly the 

 first molar on the left side belongs to an earlier set. On the right 

 .side I can find no trace of other )nolars. 



A considerable part of the posterior ))orti()n of the deutary is 

 preserved, which shows that while the j:i.\v is broiuler than in

T'danoaitchus or ])ino2^honeus, it is also relatively shorter. The 

 measurement across outside the canines is about 215 mm., and 

 with its huge canines and short jaw this new form miist have 

 been a much more lion-like carnivore than any of the jaeviously 

 known types. 



I have named this giant carnivore after Mr. Frederick P. ^^ 

 Struben, the pi-oprietor of Abraham's Kraal, who for years has 

 taken a keen interest in palaeontology, and as the result of whose 

 interest Abraham's Kraal has become the most important palaion- 

 tological centre in the Karroo. As Abraham's Kraal adjoins the 

 classical localities Jan Willem's Fontein and Vers Fontein, 

 whei'e the first South African Dinocephalians weie ol)tained, it 

 is likely tliat ere long, with Mr. Struben's .assistance, Ave will bo 

 able to clear up tlie confusion f)f tlie early ty[i('S and specimens.
