many parts of the Indian Islands. The 

 male measures five feet six or eight inches 

 from the beak to the tip of the tail ; and the 

 whole of the plumage is remarkable for 

 variety and elegance. The wings consist o f 

 very large feathers, nearly three feet long, 

 the'outer webs being adorned with a row of 

 large eyes (ocelli), arranged parallel to the 

 shaft -, the tail is composed of twelve feathers,

the two middle ones being about four feet in 

 length, the next scarcely two, and gradually 

 shortening to the outer ones. The whole 

 plumage is, indeed, so varied, that to attempt 

 to describe it fully in our limits would be 

 vain. Its voice is rather plaintive, and not 

 harsh as in the peacock. It is considered a 

 very shy bird, but one was kept alive a con- 

 siderable time in the aviary of the Zoological 

 Gardens, where the pleasing variety of its 

 plumage and the beautifully coloured skin 

 of its head were much admired.

ARGYNNIS. A genus of diurnal Lepi- 

 doptera. We here describe two beautiful 

 British species of Butterflies belonging to this 

 division. 



ARGYNNIS PAPHIA, or SILVER 

 STREAK BUTTERFLY. There are few of 

 the Lepidoptera more abundant in the woods 

 and meadows of the South of England 

 than the Silver Streak, which is known to

delight in settling on the bramble-bl 

 In the male the wings above are fulvous, in 

 the female virescent, with numerous longi- 

 tudinal and transverse black lines and bars, 

 and three rows of marginal black spots ; an- 

 terior wings beneath, paler and less spotted ; 

 the posterior wings are greenish beneath, 

 with four irregular narrow pale silvery- 

 waved bands ; between the two last is a 

 series of ocelli, with a green iris and pale 

 pupil, and on the margin is a row of green 

 crescents : the cilia of all the wings above 

 are fulvous and black, paler and ferruginous 

 beneath: the body fulvous above, grayish 

 beneath : the antenna are brownish, with 

 the club black. 



ARGYNNIS LATHONIA, or QUEEN 

 OF SPAIN FRITILLARY. This exceed- 

 ingly beautiful species, though rare in this 

 country, appears to be very common on 



the Continent. The upper surface in general 

 markings resembles that of the allied species, 

 but it may be at once known by the beau- 

 tiful and well-defined silver marks on the 

 under surface of the lower wings. British 

 specimens of it are much prized by the col- 

 lector. Our cuts will give a very good idea 

 of this insect, as we have figured both the 

 upper and under sides. 



ARICIA. A genus of Dorsibranchiate 

 Annelidas. They have neither teeth nor 

 tentacles. The body, which is lengthened, 

 bears two ranges of lamelliform cirrhi along 

 the back ; and the anterior feet are furnished 

 with dentelated crests, that do not occur on 

 the other feet. 



ARMADILLO. (JDos7/p?M.) A genus of 

 mammiferous quadrupeds, belonging to the 

 order Edentata, readily distinguished from 

 all others by the singular covering with which 

 Nature has protected them. This is a com- 

 plete suit of armour; consisting of a triangu- 

 lar or oval plate on the top of the head, a 

 large buckler over the shoulders, and a simi-
