378 PEOF. T. JEITEKY PAKKEK ON THE CEANIAL OSTEOLOGY, 



2. Mesoptertx, species a. 



A cranium and mandible from Te Ante, near Napier. (Coll. A. Hamilton.) 



This skull was referred by Prof. Hutton to Cela geranoides, but the evidence for 

 the determination appears to me to be insufficient, and I think it best to leave the 

 name in abeyance ^ 



Figured in outline, Plate LXI. figs. 28 & 41, Plate LXII. fig. 52. 



3. Mesoptertx, species j3. 



An entire skull found by Mr. A. M'Kay in a limestone fissure on Salisbury Tableland, 

 Nelson. (Col. Mus., Wellington.) 



This skull, which was found associated with the cervical vertebrae, is one of the 

 most perfect ever discovered. It does not correspond with any of the figures or 

 descriptions I have met with and appears to belong to a species the skull of which 

 has not hitherto been described. 



Figured on Plate LX. figs. 20 & 21. 



4. Mesoptertx, species -y. 



The skuU on a mounted skeleton of M. didina, from Hamilton Swamp. (Otago Univ. 

 Mus.) 



This skull difiiers from the Enfield specimens of M. casuarina in the form of the 

 orbit, which is right-angled as in Binornis. 



Figured in outline, Plate LXI. figs. 30 & 44, and Plate LXII. fig. 54. 



Genus Anomaloptertx, Reichenbach. 



1. Anomalopteetx didiformis, Owen. 

 a. Three perfect crania with premaxillae, niaxillo-jugal arches, quadrates, and mandibles; 

 all found in the same cave (with the skeletons) at Castle Rocks, Southland. 

 (Mr. A. Hamilton's collection.) 

 h. One perfect and several imperfect immature crania, from the same locality. (Coll. 



A. Hamilton.) 

 c. A cranium MitU ((associated) premaxillae; locality unknown. (Colonial Museum, 

 Wellington.) 



These skulls are assigned to this species in accordance with Prof. Hutton's 

 researches (9, p. 123), confirmed by Mr. Hamilton's discoveries at Castle Rocks. 

 The skull referred by Lydekker (12, p. 275) to this species is apparently that of 

 Mesopteryx didina. 



The most perfect of the immature crania referred to above is figured on 

 Plate LVIIl. figs. 12 & 13. 



' Since writing the above, Captain Hutton has lent me tor examination a cranium which he considers to 

 he that of Megdlapteryce tenuipes, since it was found in a cave associated with bones of that species. The 

 skull was a good deal damaged, but appears to agree very closely with that of Mesoptcry.v, species a. — 

 June 1896.
