PROCEEDINGS OF THE SOCIETY. 277 



formed the subject of a beautiful set of slides shown by Mr. 

 Reoch ; while various other interesting topographical views were 

 submitted by Messrs. Herriot, M'Lean, Somerville, and Wilson. 



29th January, 1907. 



Mr. J. Ballantyne, Vice-President, in the chair. 



Dr. T. Beath Henderson exhibited a specimen of Gecko 

 verticillatus, Laurens, and described the striking peculiarities 

 in the structure of the toes, which are characteristic of the 

 Geckinida?. The majority of the species have these organs 

 dilated into various club forms, in the lower surface of which 

 are symmetrical plates. These serve as a means of adhesive 

 progression. He also submitted for exhibition a specimen of 

 Aristelliger prcesignis, Hallow, from Jamaica, sent to him by 

 Mr. Thomas Wishart. 



Mr. John Robertson exhibited a number of eggs of the Tree- 

 Sparrow (Passer montanus, L.) from Bute. He stated that 

 the species had formerly been considered a rare bird in the 

 West of Scotland, but he had discovered a small colony of them 

 recently on the south coast of Bute, and he had no doubt that 

 they would be found plentifully in other places. 



Mr. Robert Henderson showed some specimens of Diptera 

 from Bute, amongst which were Tabanus sudeticus, Zeller, 

 T. autumnalis, L., Gyrtoma spuria, Fin., Medeterus apicalis, 

 Ztt., Ghilosia grossa, Fin., Melanophora roralis, L., Hydrotcea 

 albipuncta, Ztt., Drymia hamata, Fin., and Fucellia fucorum, 

 Fin. 



Mr. Alexander Ross, for Mr. John E. Murphy, exhibited 

 Piezodorus lituratus, Fab., from Bute, which, he stated, had 

 been captured by Mr. Murphy at Port-Bannatyne on 28th 

 September last. The species is not included in the List of 

 Hemiptera contained in the British Association Handbook, 

 and thus becomes an addition to local records. It is generally 

 distributed in England and Ireland, and is chiefly found 

 feeding upon broom and furze. Several other entomological 

 specimens were also submitted by Mr. Ross. 



Mr. Peter Ewing, F.L.S., read a paper on " Some New or 

 Little-known Forms of the Genus Gar ex" and exhibited a 

 series of illustrative specimens.
