ochraccous-lirowu, the area near posterior angle greyish, the urea beyoucl cell more or less castaneous, 

 preceded by a narrow white linear fascia extending l't oin first suhcosLal to lower median nervale ; this 

 fascia is followed by a series of five white spots, and these by a cluster of four apical spots of the same 

 colour; two dark spots are placed beyond the lower two of the five white spots. Posterior wings beneath 

 with about the upper half castaneous, the remaining area more or less ochrticeous, shaded with eitstuueous, 

 and marked with a series of white spots, most of which are shaded or margined with dark bluish ; thoso 

 epota are thus situate: — two subcostal, four (small) subapieal, four disrul, four (large, and much margined 

 with bluish) on abdominal margin, and a marginal series ■ »f lineato spots: a black spot at anal angle and 

 a smaller black spot between the two lower median nervules. Body above more or less concolorous with 

 wings; body beneath with legs greyish, mottled and streaked with brownish.

Genus NARATHURA ((fitted, p. 259). 



With a much larger accumulation of specimens thmi when I previously enumerated the 

 species of this genus found in the Malay Peninsula, and with more prolonged study and 

 comparison with other species from the surrounding habitats, I am compelled to own that 

 our knowledge of some species is still in the most unsatisfactory condition. Several causes 

 have helped to produce this perplexing confusion, a potent one of which has been the 

 difficulty in properly identifying many of Mr. Huwitson's species, owing to the very indifferent 

 figuring of the under surface of the wings (a difficulty which I have not been altogether 

 unable to overcome with the figures here given), which has led in some instances to the same 

 species being several times redescrihed by different authors, and at the same time not figured. 

 Hence it is almost impossible to verify some identifications without a reference to the typical 

 specimens. Another disturbing element is found in that principal guide to specific differentia- 

 tion, the marking of the under surface of the wings. Here so much variation exists that without 

 breeding it is impossible to say where it either begins ur ends, and the shade of blue on the 

 upper surface is often so different as to lead to only two conclusions, war,, either that we are 

 dealing with the most closely allied species, or with seasonal forms of one species.

Female. Resembling the male in hue p but the anterior wings above with a broad costal and outer 

 marginal dark fuscous fascia ; this dark colour being broadest at the apex. 



I am indebted to Lieut. Goodrich for a specimen of the female sex of this species, which 

 was probably captured at Singapore.* 



* Attitfrttrn has already been drawn to the peculiarity i>f the recurrence of deep blue coloration in different families 

 of the ltlii>i>nWtTn itintfti, p. 'JWJ„ Tin- bright golden-green coloration of N.farquhnri recalls the remarks of frof. Haockel 

 on the prevalence of ihis frtLti in the Eastern tropica. '* Kansonnut had already pointed out how singularly and universally 

 preen prevails in the coloring of Ceylon. Kot only is the greater portion of this ever-green isle clothed with an unfading 

 tapestry of rich verdure t but the animals of the m'ont widely dissimilar classes, which live in its woods, are isonspienous for 

 their green colouring. This is seen in all the commonest birds and lizards, butterflies and beetles, which are of every shade 

 i..f brilliant green. In the same way the innumerable inhabitants of the eea, of all classes, are coloured green, such aw many 

 fishes and cni*t:icc-<i. Worms \Amjihtm>Mc \, and sou anomalies iActitntu ; indeed creuLurcK which elsewhere seldom ^r never 

 appear in green livery wear it here ; for instance, several starfish {Ophiura\, sea* urchin*, sea -cue umbers ; also some enormous 

 bivalves \Truhicnit),\n^ iirachiopoda tLintjulu), and others. An explanation of this phenomenon is to ho found in Darwitt*a 

 principle*, particularly in the law of adaptation by m lection of similar cohmriug or sympathetic affinity of colour, as t have 

 elucidated m my " History of Creation,' vol. i- p. 90*. - * . . . .The green coral banks of Ceyloiu with their preponderance of 

 green inhabitant's, are as instructive as bearing on thin theory as the green land animals are which people the evergreen forests 

 and thickets of the inland; but in purity and hpk-udi-nr of colouring, the sea creatures arc even mure remarkable than the 

 fauna of the forests,"— Ebnbt Hakckkl J A Visit to Ceylon/ pp.
