It would be supposed from the above description that the ground- 

 colour of the wings in this species was pure white ; the fact that a 

 pure white form does exist in the N.E. Himalayas would convince 

 any Lepidopterist living in India that such was the case. I believe, 

 however, that had Westwood been describing the Darjiling type ho 

 would have said " alis niveis " rather than the more vague " albis." 



The typo of E. connmilis, which is now in the collection of the 

 British Museum, is of a yellowish cream-colour, not deep enough for 

 " straw-coloured ;" it differs from the white form represented by 

 Wood-Mason in nothing but its yellower colour, in which character 

 it i)erfectly agrees with its male ( E. halliroihins). I suspect it to be 

 a dimorphic species ; and if so, it would be a mistake to regard the 

 snow-white variety as a local race and give it a distinctive name. 

 In the case of E. meridionalis, however, the pattern as well as the 

 colouring (" straw-coloured," W.-M.) differs not a little ; and 

 therefore his name Avill stand for this race. 



The yellow colour of Westwood's type is not due to age, but is the 

 tint most j)revalent in specimens of Earij^iis ; were it caused by 

 time it would be rather stramineous than of the pale creamy-sulphur 

 tint which it is. Moreover, of all the examples which I have seen 

 of this species, in both sexes (and I have seen a good many besides 

 the four yellowish ones in our collection), only one female, obtained 

 from Dr. Lidderdale's series, is, as Mr. Wood-Mason says, " pure 

 and dazzling white." 



Descriptions of Spirostreptus from Marlagascar. 

 By A. G. Butler, F.L.8., F.Z.S., &c. 



By a singular lapsus calami^ I iind that I have used the term 

 "nuchal plate" in place of "first dorsal segment" in all three de- 

 scriptions (' Annals,' April 1882). The " nuchal plate " is a convex 

 and usually elliptical shield between the head and the first dorsal 

 segment, and is present in all the species of ZqJironia and Sp)luvro- 

 theriam. It is the part naturally described next to the head ; and 

 this may perhaps account for my blunder. 



The Alcyonaria of the Bay of Marseilles. By M. A. F. Maeion. 



The investigation of the Alcyonaria collected by the ' Travailleur ' 

 during the expeditions of 1880 and 1881 has led me to prepare a 

 summaiy of tlie Coelenterata of this group, observed by me during 

 the last twelve years upon the shores of Marseilles. The species 

 are numerous ; and it seemed to me that the indication of their 

 distribution at the various depths would be an important document
