Hutton. — On New Species of Moas. 11 



Euryapteryx compacta. 



This species is founded on a tibia from Enfield which 

 closely resembles that of E. gravis, but is much smaller. 

 From the tibia of M. didina it is distinguished by its greater 

 robustness, and its greater width at the distal extremity. The 

 distal extremity is, however, not expanded inwards as in 

 Pachyomis, which at once distinguishes this tibia from that 

 of P. pygmaus. Length, 15 - 2in. (386mm.) ; proximal width, 

 4 - 6in. (117mm.) ; width at middle of shaft, T6in. (39mm.) ; 

 at distal end, 2-4in. (61mm.). 



The metatarsus which I place with this tibia much re- 

 sembles that of P. pygmtzus, but has the trochlear considerably 

 more expanded. Its length is 7 - 2in. (183mm.) ; the proximal 

 width, 2-8in. (71mm.) ; middle of shaft, T6in. (41mm.) ; and 

 distal width, 3-4in. (86mm.). The femur, which I have added 

 with great hesitation, resembles that of M. didina, but has a 

 larger head. Length, 9-lin. (231mm.); proximal width. 3*5in. 

 (89mm.) ; width at middle, l-4in. (36mm.) ; distal width, 3-6in. 

 (91mm.). The association of these bones with the tibia is 

 provisional only until further information is obtained ; but the 

 tibia cannot be placed in any previously-described species. 



Pachyornis inhabilis. 



This species is founded on an incomplete individual skele- 

 ton in the Canterbury Museum, the exact locality of which is 

 not known, but probably it was found somewhere in Canter- 

 bury. It consists of the leg-bones, fifteen phalanges, a frag- 

 ment of the pelvis, and six vertebrae. 



The metatarsus has a length of 8-5in, (216mm.) ; the 

 proximal width is 3- Sin. (96mm.) ; width of the shaft, 2-0in. 

 (51mm.) ; and distal width, 4-5in. (114mm.). The inner mar- 

 gin of the entocondylar depression has no median ridge, and 

 the hypotarsal ridges (talon) are equal. The bone much re- 

 sembles the metatarsus of Euryapteryx ponderosa, but is not 

 so robust ; also the posterior surface of the middle trochlea 

 rises abruptly from the shaft, and nearly at right angles with 

 it, while in E. ponderosa it is very oblique, and merges more 

 or less gradually into the shaft. From the metatarsus of 

 E. gravis the present species can be recognised by being more 

 expanded proximally. 



The tibia has a length of about 19-5in. (495mm.) ; the 

 width of the shaft is LSin. (46mm.) ; and the distal width, 

 3;3in. (84mm.). It has the great inward expansion at the 

 distal end, which is one of the characters of Pachyornis, and 

 which distinguishes that genus from Euryapteryx. 



The femur has a length of about ll-5in. (292mm.) ; the 

 proximal width is 4-5in. (114mm.) ; the width of the shaft, 

 2-0in. (51mm.) ; and the distal width is 5-0in. (127mm.). The
