6. DENDROLASUS. 97 



Fur shorter and softer than in D. wrsinus or D. inustus. TJnder- 

 fiir vefy thin and sparse, pale grey ; face covered with the coarser 

 fur, as in I), inustus. Pur from withers to crown reversed. General 

 colour pale finely grizzled grey. Face black ; a paler band passing 

 across the forehead just in front of the ears, and ending on each 

 side in a white or yellowish spot below the ear. Ears black outside, 

 yellow within, the hair on them short and coarse. Back of neck 

 black, gradually passing into the pale . grizzled grey of the back, 

 where each hair is pale slaty grey for four fifths of its length, and 

 then has a black subterminal and a yellowish or whitish terminal 

 ring. Sides and belly pale yellowish white. Chin black ; chest 

 white or pale grey. Arms to metacarpus, and legs to end of meta^ 

 tarsus, I'lear pale yellow, darker on wrists and ankles ; fingers and 

 toes black. Tail mixed black and pale yellow, its upperside paler 

 than its lower, but with a darker patch just beyond the base. 



Skull of much the same proportions as those of D. ursinus and 

 D. inustus, but rather more delicately built. Nasals short, broad, 

 very much expanded behind, their posterior suture recurved for- 

 wards in the centre. Ascending processes of premaxillse broadened 

 above, the naso-premaxiUary nearly or quite the length of the naso- 

 maxillary suture. Interorbital space rounded, swollen and inflated, 

 its edges smooth, not ridged, but with minute rudimentary post- 

 orbital processes. Foramen magnum broader than high. 



Teeth. Incisors smaller and lighter than those of the last species, 

 cutting-edge of three incisors together only about 10 millim. I.' and 

 i.' shorter, smaller, and less thick transversely than in D. inustas. 

 Canines very small. P.* (PL XIII. fig. 1) broad and strong, difier- 

 ing markedly from that of D. inustus by having an external, as well 

 as an internal ledge and posterior talon, the main crest being there- 

 fore nearly in the centre line of the tooth, instead of on its outer 

 side. Molars as usual, but rather small in proportion.

for that day, and therefore the only information as yet available about it is 

 that it is " more nearly allied to D. dorianus than to B. ImrihoUzV The second 

 species was described under the name of D. fulvus at the October (1887) 

 meeting of the Royal Society of Queensland, and an abstract of its description 

 published in the Brisbane ' Evening Observer ' for Oct. 17, 1887. From the 

 characters there given, I am inclined to suspect that it will turn out to be only 

 an erythristic form of D. lumhoUzi, the differences appearing to consist merely 

 of the presence of rufous or fulvous in the parts ordinarily light grey in D. 

 Iwmholtzi. No definite conclusion, however, can be arrived at until Mr. De 

 Vis's full paper ia published.
