Breadth of skull at temporal fossae, 2in. to l-9in. ; at post- 

 frontal processes, 3-75in. to 3'55in. ; length of lower jaw, 

 4'5in. ; total length of head, 5in. Temporal fossae narrow, the 

 breadth about one-thkd that of the orbits. Length of the 

 ilium, 17"5in. to 16in. ; of the ischium, 8-7in. to Tin. ; breadth 

 of the sacrum, Sin. to 7in. ; depth of the pelvis, 6-2in. to 5-6in. 

 Length of the middle toe. Gin. 



Distribution. — Found in both Islands, but rare in the 

 North and common in the South. The type is from Wai- 

 kouaiti, in Otago. No. 1 is a specimen in the Otago Museum 

 found at Dunedin ;'■' No. 2 is a specimen in the Wellington 

 Museum, the locality unknown. It was very abundant in the 

 peat-beds of Glenmark and Hamilton, and occurs also in the 

 Maori cooking-places at Shag Point. A few bones were found 

 in the Te Ante Swamp, and it also occurs in the Maori cook- 

 ing-places at Wanganui and Whangarei. 



The North Island birds agree with those from Glenmark 

 Swamp in having a rather shorter tibia than the birds from 

 Otago ; while the rather older birds from Motunau agree in 

 size with the southern variety. This difference is sufficient to 

 distinguish two varieties, but is not of specific importance. 

 In Otago the length of the tibia is between 18'25in. and 

 17in., while in Glenmark and the North Island it is between 

 17*8in. and 16in. 



A sternum in the Wellington Museum from Waipawa, 

 Haw^ke's Bay, enables us to identify the sterna found in 

 the South Island. The cranium figured in Ext. Birds of 

 N.Z., pi. liii., fig. 6, may belong here, but is rather large. 

 The femora are difficult to distinguish from those of E. 

 gravis.
