is very elongated anteriorly; the first rib is strongly fixed to the side of the presternum ; the 

 spinous process of the anterior thoracic vertebra is very elongated, diminishing in size towards 

 the lumbar vertebrae, and increasing in size again towards the sacral bone; chevron bones 

 very largely developed especially towards the extremity of the tail, being often as long as 

 the caudal vertebra itself; in the pelvis there only is a trace of pectineal tubercle and nearly 

 no sideways expansion of tuberosity of ischium ; marsupial-bones feeble and straight, not 

 very broadened basaly. 



The skeleton présents 13 thoracic, 6 lumbar, 2 sacral and about 18 caudal vertebrae; 

 the mesosternum consists of four segments, xiphisternum rather elongate, as long as the two 

 posterior segments of the mesosternum. 



Phascogale Lorentzii Jentink. 



N°. 329. Young adult Q. Hellwig Mts. (2600 m.), October 24. 1909 (skin and skeleton). With 

 four young ones in pouch. 



This animal, described in „ Notes from the Leyden Muséum", 191 1, p. 234, is characterized 

 by its large size, long fur, shining black colour, white ears, white extremity of tail and very 

 elongated claws. 



The fur is very long and very dense — not adpressed like in other Phascogale- 

 species — longer than in any other Phascogale known to me. Head with thick set black 

 hairs, like the anterior part of back, broadly between the shoulders and like the posterior 

 part of back together with the tail for its three fourth ; the midmost part of back black also, 

 but some hairs hâve a whitish subterminal ring, giving those parts a fine grizzled appearance ; 

 the latter colour dominâtes also on the shoulders and haunches; underparts of a dirty yellow 

 suffused with some brownish red ; feet black, hands sooty; ears exteriorly white haired, inside 

 black haired, margin of ear white; distal part of tail for one fourth pure white haired. Claws 

 stronger and larger than in any other P/iascogale-s-pecies known to me.

Under Nouhuysii a few observations concerning skull and dentition. The skeleton présents 

 7 cervical vertebrae, 13 thoracic, bearing ribs, lumbar 6, sacral 2 and caudal vertebrae 25. 

 Sternum with a squarish presternum, the mesosternum consists of four segments, and the 

 xiphisternum has a spade-form, with a broad cartilaginous expansion posteriorly; the xiphisternum 

 is somewhat longer than the two posterior segments of the mesosternum together; the fourth 

 segment of the latter has not the hour-glass-shape of the other segment, but is posteriorly 

 broadened and sideward eut off for the attaching of the sixth and seventh ribs. The posterior 

 margin of the ischium is very curved, the tuberosity of ischium well developed ; anterior 

 margine of ischium rather concave; marsupial bones strong and straight.
