Mexico. It was interesting fioixi the fact that its hoiiis instead 

 of having grown naturally had become crumpled into a mass of 

 spongy matter still covei'ed with the velvet, and exhibited 

 the morbid growths into which the horns of deer often develop 

 when the animal's genitals are injured. In such cases, not only 

 does the deer cease to shed its horns annually, but they often 

 cease to bear horns at all. Sir Henry suggested that some expe- 

 riments might be made to try and discover a little more closely 

 the physiological cause of the aborted horns ; this might perhaps 

 throw some light on the apparently anomalous fact that in the 

 various races of Reindeer both sexes have hoi'ns. 



Mr. R. E. Holding exhibited and made remarks upon the lower 

 jaw of a Highland Ram in which the last molar tooth was re- 

 duplicated on both sides, and called attention to a curious outward 

 deflection of the coronoid process and its projection beyond the 

 condyle, and the consequent alteration of the sigmoid curve and 

 adjacent parts, the last molar being also pushed out of its normal 

 position by the persistent growth of the reduplicated tooth, 

 Mr. Holding was under the impression that these variations in 

 the form of the jaw were attributable to alterations in its move- 

 ment to accommodate the supplementary molars. 



The following extiuct from a letter addressed to the Secretary by 

 the Rev. Francis C. R. Jourdain, of Clifton Yicarage, Ashbourne, 

 Derby shii'e, was read : — 



"In the P. Z. S. for 1901 (vol. ii. p. 216) there appeared an 

 article by Mr. J. G. Millais, F.Z.S., on the ( supposed) second 

 occurrence of Bechstein's Bat in England. 



" This, of course, was an error, as two specimens of this Bat were 

 taken by my friend Mr. E. W. H. Blagg, of Oheadle, Staflford- 

 shire, in the New Forest in 1886, and identified at the British 

 Museum {see 'Zoologist,' 1888, p. 260). How Mr. Lydekker came 

 to overlook this in writing his ' Handbook of British Mammals ' 

 I cannot understand, as Mr. Blagg's specimens passed through 

 the hands of Mr. Oldfield Thomas. I wrote at the time to 

 Mr. Millais, who expressed his intention of making the correction. 

 As he has not done so, I beg to be allowed to point it out." 



Dr. C. W. Andrews, F.Z.S., exhibited specimens and lantern- 

 slides illustrating a collection of fossil vertebrates obtained from 

 the Fayum district of Uj)per Egypt during the last winter. 



The most interesting of the new forms here brought to light 

 was Arsinoitherium zitteli, an extraordinary Ungulate discovered 

 by Mr. H. J. L. Beadnell last year. This animal was chiefly 

 remarkable for the enormous bifid bony horn borne on the nasal 

 region ; there was also a pair of small conical horns over the
