resemblance to the Stos erymanthius of the Pikermi beds, though 

 in its tooth-structure this latter animal was a typical Sus. ^ 



Hylochcerus showed no relationship to Potamochcerus either in 

 the structure of the nasal region or the character of the lower 

 canines, these being of the more primitive shape found in Phaco- 

 chcenos and the Stis verrucosus group, while in Potamoch'xrus they 

 were of the more specialized type characteristic of S'us scrofa and 

 its allies. 



Dr. P. Chalmers Mitchell read a paper on the African 

 Crowned Cranes, giving notes on the distribution and characters 

 of the species. He recorded the extension of the lange of the 

 Cape form, Bcdearica regulorum, to Kavirondo, in Uganda, and 

 he described as new a species founded on specimens obtained by 

 Lady William Cecil at Khartoum and presented to the Society's 

 Gardens : — 



Balearica CECILIA, sp. nov. ^y- 



Similar to P. pavonina, and hitherto confused with it. Smaller 

 and darker, beak shorter and black to the tip ; cheek-patch red 

 below, white above, but the white area very small. 



Mr. J. Lewis Bonhote, F.Z.S., read a paper on the " Mouse- 

 Hares " of the genus Ochotona inhabiting the Palasarctic Region. 

 It was pointed out that the various species might be easily divided 

 into three divisions, from a study of their skulls, the differences 

 lying chiefly in the incisive and palatal foramina. In the first of 

 these, the Ladacensis group, the two sets of foramina were 

 entirely separated by the bony palate; in the next division, 

 called the Eufescens group, there was only one large foramen 

 slightly constricted in the centre ; and in the last division, called 

 the Curzonice group, the large foramen was triangular in shape. 

 The paper dealt fully with the various species, their seasonal 

 changes, and distribution. One new species belonging to the 

 Eufescens group was described under the name 0. wardi, after 

 Col. A. E. Ward, who had collected it in Kashmir. It was of 

 moderate size, and of a uniform iron-grey in winter, becoming red, 

 especially about the head and neck, in summer. Since the paper 

 was written, Mr. Lyon, jun., in a paper on the whole of the 

 Duplicidenta, subdivided the genus Ochotona into three subgenera, 

 \iz. Ochotona, Gonothoa, and PiVca ; these subgenera coincided with 

 the three groups mentioned above, viz. Curzonice, Eufescens, and 

 Ladacensis respectively. 



A communication from Prof. W. Blaxland Benham, F.Z.S., 

 contained descriptions of twelve new species of Eirthworms from 

 the North Island of New Zealand.
