men proved to be the remains of a kangaroo, for it included the 

 characteristic innominate bone. Unfortunately the specimen 

 was very incomplete. There was no trace of the skull, and the 

 only relics of limbs was a broken femur. The rest of the fossil 

 consisted of part of the vertebral column with the remains of 

 about ten ribs, and fragment of a scapula. The bones were 

 brittle and fragile, and they were imbedded in a hard, tough, 

 sandy limestone. Owing to the limited time during which the 

 fossil was exposed above the sea, its complete extraction would 

 have been impossible, even had it been thought worth while to 

 quarry out the whole of the live foot slab of limestone over 

 which the bones were scattered. 



Accordingly we devoted our attention to the pelvis, which was 

 skilfully quarried out by Mr. Spry. We obtained also the best 

 of the vertebrae, a fragment of a scapula, and some parts of ribs. 



That the pelvis belongs to a kangaroo is obvious. The part 

 shewn is the inner surface of the right innominate ; most of the 

 ilium is preserved, but the fore-end is broken off. The hinder- 

 end of the ischium and nearly all the pubis are lost, but enough 

 of the obturator foramen is shewn to enable its outline and size 

 to be approximately determined. A photograph taken by Mr. 

 Fowler some time before our visit showed most of the pectineal 

 process and the outline of the proximal part of the pubis. 



The following dimensions show the relative sizes of the fossil 

 with the largest pelvis of Macropus giganteus, Zimm., in the 

 University Biological Museum, and in the largest Macroptis 

 pelvis in the National Collection, which have been kindly shown 

 me by Mr. T. S. Hall, and Mr. J. A. Kershaw, respectively.
