This species is readily distinguished from .1. imbicas Heugl. fouud in Jliddle 

 Egypt, which in size and colour it rather closely resembles, by its much shorter 

 hind legs and feet, and in this respect it resembles the much larger aud more 

 brightly coloured animal from Tokar and Suakim, described in the footnote.* 



23. Hystrix. 



" The porcupine is apparently absent from Shendi, though verbally reported 

 to be there by Europeans. The natives, who know this animal well, call it 'Abou 

 Shok,' i.e. Father of Thorns." >'• C. R. s: A. F. E. w. 



24. Lepus aethiopicus Hempr. & Ehrenb. 



Eight skins, Nos. 2, II, 14, 15, 16, 19, 20, 55. February and March. 



" This hare is common in the desert on the east bank of the Nile, and rare on 

 the west. It occasionally can be put up from the scrub near the river bank, but 

 is always shy and wary. Native name ' Arnab.' " N. c. K. k A. F. E. w. 



ON SOME LEPIDOPTERA. 



By the HON. WALTER ROTHSCHILrD, Ph.D., and KARL JORDAJST, Ph.D. 



(Plates IX. X.) 



ON the plates accompanying this article, we have put together specimens of very 

 different size and colour, with the purpose of trying whether such a motley 

 of forms could be well reproduced by the three-colour process. Though the plates 

 are altogether too red, the larger figures are magnificent, especially those of the 

 Satnrniids. No artist could reproduce the details so exactly as these prints do. 

 The metallic green and blue colours do not come out well ; and the yellow and red 

 tints are not bright enough. The small figures are not so satisfactory as the large 



ones. It would perhaps be better to have only small species on a plate. The 



three-colour process will doubtless become more perfect in the course of time ; but 

 even as it is, tlie productions of the process surpass by far those of hand-work as 

 regards the details of pattern. 



1. Papilio victoriae isabellae subsp. nov. 



S. Differs from rict. tictoriac in the green subapical patch being longer as well 

 as broader. It extends basad to the fork or farther down, and is often connected 



* I take this opportunity of describing a form of Acomys from Suakim, which has lived in tlie gardens 

 of the Zoological Society of London for several years and has been mentioned in their list of animals 

 as A. kuHteri. The name was proposed by the late Dr. J. .\nder8on, who obtained the specimens from 

 Gen. Sir Archibald Hunter, then Governor of Suakim, but unfortunately a description was never published. 

 Acceptini? the name thus proposed, it may be described as of robust form with moderate ears and very 

 short hind feet. General colour above, red fawn, all the underparts pure white. Distinguished from 

 A. liimidiatus Cretzschm. by its shorter cars and hind feet. Measurement of the type from the Plain 

 of Tokar (wild killed), No. 58 3 in Dr. Anderson's collection : head and body 103 mm. : tail, 102 mm. ; 

 forearm and hand, 26 mm. : hind foot, 17'5 mm. ; ear, 16 mm.
