478 THE ZOOLOGIST. 



Mr. Oldfield Thomas read a paper " On Further Collections from Nyasa- 

 land," being a continuation of three previous papers on the Mammals of that 

 country. The specimens referred to had been collected and sent home by 

 Sir Harry Johnston, Consul Alfred Sharpe, Dr. Percy Rendall, and Mr. 

 Alexander Whyte. Two species were described as new : a peculiar hoary- 

 coloured Baboon from Fort Johnston, proposed to be called Papio 

 pruinosus, and a Steinbok with white streaks in its fur characteristic of the 

 Grysbok. The latter had been obtained by Mr. Sharpe in Southern Angoni- 

 land, and was proposed to be called Raphiceros sharpei. 



Mr. W. E. de Winton read a paper on some Rodents from Mashonaland 

 and Matabeleland, British South Africa, collected by Mr. J. Ffolliott Darling 

 and Mr. F. C. Selous. This memoir contained descriptions of six species and 

 two subspecies of rodents new to science. Amongst these were a Dormouse 

 very much smaller than Graphiurus murinus, to which the name G. nanus 

 was given; a Pouched Rat, which was called Saccostomus mashonce ; and a 

 Mole-rat, proposed to be called Georychus nimrodi. 



A communication was read from Mr. Alfred E. Pease containing notes 

 on the Antelopes of the Aures and Eastern Algerian Sahara. 



Communications were read from Dr. A. G. Butler on two collections of 

 Lepidoptera made by Mr. R. Crawshay in Nyasaland; and on a collection 

 of Lepidoptera from Nyasaland, collected by Mr. J. B. Yule. 



A communication was read from Mr. Joseph I. S. Whitaker, containing 

 field-notes on the Gazelles of Tunisia. — P. L. Sclater, Secretary.

Mr. McLachlan exhibited a collection of the cast nymph-skins of more 

 than one-third of the species of European dragon flies from the Departe- 

 ment de l'lndre, France, sent to him by Mons. Rene Martin. Two or 

 three of the species had been reared in an aquarium, but most of them 

 were identified by finding the imago drying its wings near the cast skin. 



Mr. R. Adkin exhibited a series of Acidalia marginepunctata taken on 

 the coast at Eastbourne, during the past eight summers. The series 

 included a bone-coloured form with pale transverse markings; others much 

 dusted with black scales, giving a deep grey tone with well-developed 

 markings; and sundry forms intermediate between the two; also three 

 taken this year, in which the whole of the wings, with the exception of a 

 pale submarginal line, are densely covered with black scales, presenting a 

 similar appearance to the so-called " black " forms of Boarmia and 

 Tephrosia. 



Mr. Donisthorpe exhibited a female specimen of Dytiscus circum-
