of its geographical distribution, and partly because a range of 

 variation of two inches in the metatarsus is much more than 

 what has been allowed for the species of Syomis and Cela. 

 It will be seen also that there are three types of skull m 

 Euryapteryx. 



Euryapteryx gravis.

Breadth of the skull at temporal fossas, l-85in. to 

 l-75in. ; at post-frontal processes, 4-lin. to 3-lin. Length 

 of lower jaw% 4-4iu. to 4-3in. Total length of the head, 

 5in. The temporal fossae are broader than in the other 

 species, being about one-half of that of the orbits. Length 

 of the ilium, 12in.; breadth of the sacrum, 6in. ; depth of 

 the pelvis, 5in. 



Distribution.— The type is from Kakanui, near Oamaru. 

 It was common in the peat-beds at Hamilton and Glenmark, 

 and in the Pleistocene deposits at Motunau. It also occurs at 

 the jMaori cooking-places at Shag Point. No. 1 is from 

 Hamilton.
